Indico 3.3

We're happy to announce the deployment of Indico 3.3! This release brings a lot of new features and improvements, including a new Check-in app, accessibility improvements (a11y), document generation and a whole lot more.

The full change log can be found here.

♿️ Accessibility improvements (a11y)

The accessibility of Indico has been improved in this release, in-line with the WCAG 2.1. This means that Indico is now easier to use by people with disabilities, including those who are blind, deaf, or have limited mobility. Notable improvements include:

  • Making language selection, timezone selection and search functionalities more accessible to those using screen readers
  • Improving accessibility of registration form fields
  • Preventing icons from being read out by screen readers
  • Including the selected language in the page metadata (for screen readers)
  • More screen reader-friendly CAPTCHA when registering for events and creating an Indico account

📱 Check-in app

The existing Indico check-in mobile application has been completely rewritten. Instead of a native app released on two separate platforms (Google Play Store and Apple App Store), it is now a progressive web app (PWA) which can be easily installed on the two major phone OSs (Android and iOS) and used offline. The new app is compatible with any Indico instances running version 3.3 (currently that's only the CERN instance and the JACoW instance) - you can access the app here.

🧾 Document generation

A long-awaited feature: Indico now supports the generation of fully customizable PDF documents. You can create receipts, certificates of attendance or any other document you might need. Once generated, participants can download their documents from the registration page.


Note that creating document templates requires knowledge of HTML and CSS and for security reasons is restricted to Indico admins. Document templates are created at the category level and are available to all events within that category (and its subcategories).

📅 “By Weekday” Recurring Bookings

The Room Booking module now supports recurring bookings that repeat on specific weekdays. For example, you can now create a recurring booking that repeats every Monday, Wednesday, and Friday over a set period of time.

⚖️ Privacy improvements (GDPR compliance)

Users can now export a copy of all their personal data stored in Indico.

🔗 Auto-linker for minutes

This feature allows Indico administrators to define specific text patterns which will be automatically linked when the patterns are used in minutes. This will save you time when adding links to e.g. ticketing systems, issue trackers or any other external systems. This feature is available for both the Markdown and HTML editor.

🔐 ACLs for menu entries

When adding custom menu entries to an event, event organizers can now restrict who can view those entries. For example, you can configure a custom event page to be visible only to participants registered with a specific registration form.

🇮🇹 Ciao Indico!

Italian has been added as a new language in Indico. This was done thanks to a team of volunteer translators who worked hard to make Indico even more familiar to the more than 65 million italian speakers around the world. We promise the translation is pineapple-free.

Want to help us translate Indico into your language? Learn more here.

📈 Other improvements and small features

  • Paper Editors are now allowed to edit their review comments
  • The number of future months shown in a category is now configurable
  • Support for generating tickets and badges for each of the registrant’s accompanying persons (this includes CERN visitor badges!)

We hope you enjoy using Indico 3.3!

Adding images to minutes

Do you often need to add an image to the minutes, and always found it annoying that you first have to upload it as a material and then link to it? There's an easier option now!


You can simply drag-and-drop an image file into the editor, or paste it from your clipboard. When doing so it will be automatically uploaded as material and inserted in the text - no more going to the Material Editor manually for this.


This also works when editing the description of your event.

Indico 3.2

We're happy to announce the deployment of Indico 3.2! This release is the result of about six months of development, and it includes many new privacy features that will make it easier for Indico events to be compliant with data privacy laws (e.g. GDPR or CERN's OC11). In addition, there has been work on modernizing some parts of the user interface, we’ve added a useful integration with OwnCloud, and the ability to favorite events along with some other features which we detail further below.

The full change log can be found here.

Privacy features ⚖️

One big set of features arriving in version 3.2 are those related to privacy. We’ve added a new privacy dashboard in the event management page, which enables managers to designate a data controller and to set a custom privacy notice.

That privacy information will be clearly visible in all events: meetings will show it in a popup in the top right corner of the title —as shown in the left image below—, and conferences in a separate page with its menu entry (right image).

Another addition is configurable participant visibility. This allows event managers to fine-tune who can see the participant list. It can be configured to show all participants, none, or only those that consent, and it can be applied independently to event participants and to all other users. It can be set up in registration forms, and when adding participants to a meeting. Event managers can also hide specific people.

If managers set the explicit consent request, registrants will be shown the different options in the form.

Retention periods have been added in multiple places: registration form, registration form fields and participant lists. This enables data to be forgotten at a certain time after an event has taken place.

Favorite events ★

Users can now have favorite events! This was a missing feature that completes users being able to set favorite categories.

To add an event to your favorites, just click on the star in the top button bar of the event’s page.

Favorite events are now visible in the dashboard as well as in the favorites section of the user settings.

New registration forms 🎟️

The registration form has been completely reworked and modernized, making it much easier to use by registrants and customise by the event managers. Many of the previous registration form limitations and bugs are now resolved, like the handling of long labels and titles.

All the fields which were available before are still there, but with improved looks and extended configuration options (including the retention period previously discussed in the privacy features).

Accompanying persons field

Along the old fields, a new one for accompanying persons has been added. This field lets registrants add people who will attend the event as their guests.


Another upside of the new registration form is plug-ins are now able to extend it in a much more neat way, hooking into it as well as adding custom field types.

CERNBox integration

Cloud storage and online collaboration tools are widely used. Some times, event managers who have been working in one of these services want to upload files straight away to their meetings or conferences. To help in this task, we’ve integrated CERNBox into Indico. Event and category managers are now able to pick up files directly from their CERNBox space and attach them as materials.

For this, a new button has been added to the materials management page of both events and categories.

It will open a dialog with a browser to select the files they wish to attach from their personal CERNBox storage.

Other improvements and small features

  • It is now possible to add extra images to badges and posters in the designer
  • Speaker-only menu entries can now be added from the event customisation section
  • Basic markdown formatting (e.g. for clickable links) is now supported in the registration section & field description
  • The person selector, widely used throughout Indico (to select speakers, chairpersons, etc.), has also been modernized
  • The editables list filter has been improved and now includes many more useful types of filters in a easy to use interface
  • There is a new setting to notify contributors via email when a new comment is made on their abstract. This will help improve the communication flow between reviewers and contributors. You can find it in the reviewing settings dialog, inside the call for abstracts management page.

We hope you will enjoy using Indico 3.2!

Indico 3.1

We are very happy to announce the deployment of Indico 3.1! This release includes some interesting new features which will enable users to better organise their events and keep categories clutter-free and tidy.

The full change log can be found here.

Category moderation 👩‍⚖️

The first big feature included in version 3.1 adds a new way to manage categories: moderation. When you enable moderation in a category, only users with creation rights will be able to create events in it. Other users who want to move events into that category require approval from the category managers.

Category moderators are presented with a list of requests and they can approve or reject them one by one or in batches; providing a reason if they think it will help the requester.

Event moderation can be enabled in the protection settings of a category.

Unlisted events 🙈

Users are now able to create events without listing them in a particular category. These events will only be visible and accessible to the creator and anybody they actively grant access to.

The idea behind this is to allow event managers to work on preparing their event away from public view until it is ready to go. This is especially useful when the target category is moderated using the previously mentioned feature.

Unlisted events can run their entire lifetime without being listed in a category, but this should typically be done only for very ad-hoc events not worth archiving; many Indico instances are in fact used to preserve the history of events and meetings, and this of course implies categorizing them properly.

Keeping an event unlisted may also come in handy for a quick test event which does not require a category.

To create an unlisted event, a new option has been added to the new event form.

Event managers can later on publish the event into a category from the management page.

There is a list of unlisted events in the user’s dashboard.

Category logging 📖

There is now a log of all the changes that happen in a category, similar to the event log. The log will show any changes to the protection settings of a category, as well as event move requests and approvals/rejections. This makes the log a useful companion to the new moderation and listing features.

Custom registration tags 🏷️

Event organizers can now add custom registration status tags to help them categorize their registrants. They are useful to filter registrants when doing repetitive tasks, like mailing. The tags are associated with an event and can be created on the registration management page.

Using these tags, an organizer can also filter the registrations for an event. This can help in tasks like contacting the registrants and other similarly repetitive chores.

Other improvements and small features

  • Reminder emails are now sent individually with the recipient in the To field instead of using BCC
  • Event managers can now import registration invitations from a CSV file
  • It is now possible to display the videoconference join button on the home page of a conference

  • Event labels are now shown in category overview tables and iCal event titles
  • Event managers can now see the end-user view of the timetable even while in draft mode
  • Event/category role members can now be exported to a CSV file

We hope you will like this new release of Indico!

Indico 3.0 🔍

It’s with great pleasure that we announce the deployment of Indico 3.0. It is a very important milestone in the history of the Project. Two ground-breaking developments happened during these last months, one of them very visible, while the other one not directly noticeable but nonetheless of vital importance. But lets get to it!

A brand-new Search

For many years, Indico used a proprietary solution based on Sharepoint Search. This was very useful in the past, as it allowed us to save resources and focus on other parts of the product. It had, however, the inconvenience of not providing an out-of-the-box solution to other Indico users around the world. Those had to find their own solutions or just conform to using Indico without a proper “search” option.

But that will no longer be the case. Thanks to a collective community effort spearheaded by CERN but which also included colleagues from Fermilab and BNL, we managed to produce a new reusable search module for Indico, backed by Elasticsearch. The backend of this module is based on Citadel, an Invenio-based microservice which is made possible by our colleagues in IT-CDA-WF and IT-CDA-DR. Many thanks to them for this cross-section collaboration which will greatly benefit the community as a whole!

The main advantages of this new search interface, from the user’s point of view, are:

  • New Indico-native interface - an interface which is integrated with Indico in a tighter way (as opposed to the previous one, which was “embedded” into the tool);
  • New text-based search options - you can search by based on a specific field, by prefixing your keyword with field:. For instance, to look for all events named “Indico developers review meeting”, you would write title:"Indico developers review meeting";
  • You can now search within Notes/Minutes - this is a long-awaited feature which is now made possible by this new search engine.

Smaller Indico instances that may not need such a powerful search engine and prefer the simplicity of not deploying a separate microservice will also benefit from a basic integrated search.

User avatars in more places

Back in Indico 2.3 we first allowed you to set your own profile photo/gravatar/identicon. We are now extending its usage to more parts of the application:

  • Lists of participants in Meetings;
  • Reviewing timelines;
  • Event logs;
  • User menu in newer interfaces.

Mixed categories

In the past categories were restricted to contain either events or subcategories. This is no longer the case; any category may now contain a mix of both events and subcategories. To ease the transition for category managers, the update restricts event creation in all categories that have subcategories, so by default only category managers will be able to create events in those categories.

Other nice things

  • We now allow adding groups/roles as “authorized abstract submitters”;
  • Paper peer reviewing and Editing data can now be exported to JSON;
  • Contribution duration fields now use a widget similar to the time picker that makes selecting durations easier;
  • iCal/ICS files can now be automatically attached to registration confirmation and event reminder emails;
  • Lots of fixes in iCal support - ICS files now include contact data, event logo URL and, when exporting sessions/contributions, the UID of the corresponding event;
  • When cloning events, surveys may now be cloned as well;
  • There are new meeting themes with numbered entries (standard_numbered and standard_numbered_inline_minutes).

Python 3 🐍

Although this is an important change, it is one which is practically invisible to regular users. Indico is now using Python 3.9, abandoning the deprecated 2.7 version. In order to celebrate this transition, we decided to increase Indico’s major version number to 3.

We hope you will enjoy Indico 3!

Indico 2.3 - "Made at home"

We are very proud to announce version 2.3 of Indico. This is the product of many months of development effort which encompassed, among others, the greatest world-wide lockdown ever seen. But even during the peak of the pandemic, Indico development never ceased, thanks to the resilience of the team and the help of the community.

The result is one of the richest Indico updates seen to date, with the new Paper Editing workflow representing the bulk of the effort but also including a plethora of improvements and fixes in various parts of the application, in great part thanks to contributions from the Community. In this regard, we would like to thank in particular the team managing Indico at the United Nations Office at Geneva for their contributions back to the Indico code base, as well as IEEE for having funded some of the developments.

You will find below a list of the most relevant features. The release changelog provides a full account of all improvements and bug fixes. You can also read this article in the Indico Project Blog.

Editing Module

The flagship feature of this Indico release is the brand-new Editing module. It is meant to augment the features offered by the already existing Peer reviewing module (previously called Paper Reviewing), by providing an integrated and customizable workflow for Academic Paper Editing, as well as associated materials (posters and slides).

Choose what to review

You may choose which files in your contribution you would like to be reviewed - would you like to review the slides of all presentations? No problem.

Decide which files are accepted

The new Editing module introduces the concept of File type. Not only can you decide which file extensions are accepted and which naming conventions have to be followed, you can also decide which files are necessary for reviewing to be possible.

Wait for the files to arrive

Indico will enforce the file extensions and name format defined above.

Review the submitted material

Whether it’s papers, posters or slides, you will be able to request and suggest changes, as well as accept or reject the submission.


Registration Status in Contribution List

Thanks to this feature, it is now easy to see whether your speakers have already registered or not.

Reset Registration Approval

Event managers now can reset the approval state of an event registrant.

Contributions and Timetable

“Draft” state for Contribution List

The Contribution List of new events will from now on be, by default, in “Draft” state. This ensures that contributions and all related menu items (e.g. Contribution List, Author List, Speaker List, Timetable) will be hidden from visitors. Whenever you are ready to publish your timetable, you can switch it to “Published” state.

Attention: This is only valid for newly-created events. Old events will remain in “Published” state unless changed.

Programme Codes

Indico can now generate programme codes for (sub-)contributions, session and session blocks, based on pre-configured sequences. These codes can be bulk-assigned and used to identify the corresponding event structures.

Protection and ACLs

Limit access to Registrants

A highly requested feature since some time, events can now be set as accessible to registrants/participants only. It is now also possible to restrict invididual materials and custom conference menu items (links and pages) to registered users.

Category Roles

Category-specific groups of users (Category Roles) can now be created. They can be used across the category, allowing for more efficient protection of your events.

These list of roles can also be imported from CSV files.

Import Roles from CSV file

User lists for roles (including new “Category Roles”) can now be imported from CSV files.

“Add myself” button

You can now easily add yourself to any author list (abstracts/contributions).

Clearer display of implicit permissions

Some roles may imply, by definition, having access to the event. Indico now displays those in a clear way.


Editing Permissions

A recurring problem with some events was that allowing all (co-authors) to edit an abstract was undesirable. This behaviour can now be fine-tuned. You get to choose you can edit an abstract and later get submission rights over the resulting contribution.

Affiliation checks

When assigning papers to reviewers/judges managers are now shown the affiliation of the person in question, as well as a warning in case it overlaps with that of the paper.

Download Book of Abstracts in LaTeX

If you need to make changes to your Book of Abstracts before having it published/printed, you now can extract the LaTeX source code directly from Indico!

Track Groups

You can now group tracks together. “Track groups” allow you to have more fine-grained control over your abstracts while keeping things organized.

Room Booking

“Quick Cancel”

Booking reminder e-mails now include a link to a “quick cancel” dialog.


Profile Photo

You can now set a photo/avatar on your Indico profile. We plan to slowly start using this image in places where your name shows up.

Note: This is obviously opt-in and there is no synchronization with the photo CERN has on file for your access card.

Improved Profile Layout

Still recognizable, but more spacious and more usable!

Download Events in ICS/iCal

You can now download an ICS feed with the events on your profile. This allows you to keep track of your Indico events on your mobile phone on favourite desktop Calendaring application.


Override Map URL

You can now override the Map URL which will show up on your event’s display page. Before you could only have a map URL for rooms managed by Indico.

Filter Event Log

The event log now allows filtering by related entries. This only applies to new log entries.

UI Improvements

“Navigate” Button

The new Navigate button allows you to quickly search for categories and access them directly.

Better time picker

We regularly get feedback from users who have issues with their browser’s default time picker widget (most often on Microsoft Edge). This could result in some users being locked in to AM/PM instead of 24h, or even “buggy” behaviour.

In order to save some of our users from that frustration, we have decided to use an Indico-specific time picker widget. We still believe general-purpose browser-based widgets are the way to go, but unfortunately not all browsers are fully there yet.

Mar 23, 2020

Do you need to cancel your event?

During the current times, it’s unfortunately very common that events need to be cancelled or postponed.

To avoid having to edit the title of the event with a (somewhat ugly) "CANCELLED" message, event managers can now add a label to their event, which shows up on both the event page itself and also in the list of events in the category.

To do so, go to the management area of your event and edit the last block of general settings:

There you can select a label, and optionally enter a message that will show up in a tooltip when hovering the label:

It will look like this when viewing the category/event:

🚗 Coming to CERN by car?

Visitors registering via Indico for events taking place at CERN can now request access to the Organization’s premises with a car.

In addition to your personal data, you will be able to specify as well your license plate number. Upon sending you the newly-crated badge, Indico will send your vehicle’s plate to CERN’s Access Management System (ADAMS). As a result, you should be able to enter the site using the license plate-scanning gates located in entrances A and B.

Please note that you will still have to go through badge control . That means that all occupants must be in possession of a valid visitor or employee badge.

If you are organizing an event, you can learn more here on how to use Indico to streamline access to CERN.

Aug 21, 2019

New URL shortener available

While Indico always allowed event managers to create a shortcut like<something>, those URLs are still somewhat long and thus not particularly great to include on posters or slides with limited space.

Because of this we just launched our own URL shortening service,, which lets you create very short URLs for any Indico link.

As a normal Indico user, you can generate a random five-character short URL for the current event using the button in the event header:

If you are an event manager, you also have the option to create a custom, more descriptive, shorturl, such as This is also done by using the button in the event header:

If you want to shorten the URL to any other Indico page, use the “URL Shortener” link in the footer:

Jun 13, 2019

Changes in Assistance workflows

With the latest Indico deployment, we have also slightly changed the workflows for requesting assistance with videoconference and setting up a room. While in the past these were requested while making a room booking, they are now instead associated to the respective Indico event.

  • From your event, click on Services → Logistics;
  • You will find the options Videoconference Assistance and Room Assistance.

New Room Booking Interface

We are happy to announce the deployment of Indico 2.2, which includes, among other things, a brand new Room Booking User Interface. If you use Indico mainly to reserve rooms, we are sure you will appreciate this release, since it solves many known issues with the previous User Interface while making it faster and much simpler to use.

Some examples of common complaints about the Room Booking system were:

  • The UI was not forgiving enough - changing your mind or looking for an alternative meant a lot of extra work;
  • There was a lack of flexibility in some options - for instance, it wasn't possible to create bi-weekly bookings;
  • It was impossible to focus on the rooms you really care about - since not all rooms in the Organization are necessarily of interest to you.

The new Room Booking Interface solves these and many other issues.

Among others, this user interface introduces:

  • Easy filtering of results;
  • Easy switching between views;
  • Integrated map-based view;
  • Alternative booking suggestions;
  • Possibility to split recurrent bookings when modifying them;
  • Better ways to create bookings from events;

You can consult a more exhaustive description of those features in this blog post.

Not only Room Booking

But Indico 2.2 also includes some other things you will like:

  • A better event log interface - it can handle events of any size with no performance degradation;
  • Possibility to customise, per event, the way speaker names are displayed;
  • Lots and lots of bug fixes and small improvements - those technically inclined can consult the full list here;

April Fools' Day!

If you thought there was something “fishy” about CERN Showers, then you were right. Indeed, it’s not a new service, just an April Fools’ joke from the Indico Team!

It seems like we’ve managed to fool many of you! Throughout the day, we got all kinds of reactions to the announcement of CERN Showers: those who believed in it, those who were in doubt as well as those who understood it was a joke and even decided to play along!
Some called it a “well-crafted” April Fools’ joke, others thought that it seemed too “intricate”, so it had to be true. We also know there are people who didn't find it funny at all. Whatever your opinion is, we are happy that CERN Showers landed just on the border between plausibility and the absurd.

Here are some facts about this joke:

  • The source code is basically copy-paste from another Indico (non-joke) module we have developed over the last few months (Burotel), with some small adaptations. It’s available on GitHub;
  • You will be able to use this UI to book meeting rooms very soon, when Indico 2.2 comes out!
  • The data about the showers and their location is true (as well as the photos), except for the number of showers available (we didn’t have time to find the exact values, so just randomized them);
  • We launched the site by the end of the 31st of March (Geneva time), which created some confusion. We did that in order to maximize the number of timezones that were covered;
  • Around 750 users had created an account at CERN Showers by the end of the day;
  • You have managed to come up with very creative reasons for your bookings. Here are our favourites:
    • This is SOOOO great ! With the recurring booking feature, I’ll never forget a monthly shower anymore !
    • IR-ECO-CO team building event including foam party etc.
    • Test of my new dinghy boat. Catastrophic flooding expected.
    • Not allowed to wash walrus in office.
    •  Hadronic shower collaboration meeting. Bubble chamber section after coffee break. Vidyo not available, bring your own soap
    • Rubber duck collaboration meeting 🦆🦆🦆
    • J’aimerais garder les idées fraîches…
    • Need to test my new armrests in a safe environment
    • I’ll be using it with a friend (Note: we're pretty sure this would break a few CERN rules)
  • No showers 🚿 were harmed in the making of this joke.

CERN Showers 🚿 - A new booking site, powered by Indico

Do you need a refreshing odour-killing shower right now? Are you worried that you will arrive at the dressing room and find all shower compartments taken, having to awkwardly wait while your co-workers walk around in undergarments?

A scientific study from the University of Los Angeles has found out that there is a strong inverse correlation between shower waiting time and employee happiness. In some of the studies that were conducted, an improvement of 400% in productivity was verified once a portable shower compartment was placed in the test subject’s office. In another case, a 30 year-old male employee decided that waiting in line while his co-workers shower was just too absurd and quit the study.

As Indico 2.2, which will include a brand new Room Booking interface, approaches its release date, we have decided its technology is now ready for some battle-testing. So, we got the whole team together for an afternoon hackathon at the dressing room in bldg. 28 and came up with a new Open Source Indico plugin that implements a full-fledged Shower Booking System based on the new Room Booking module. This is the same strategy we’ve chosen to implement the new version of the Burotel desk booking system.

The CERN Showers service is the result of this team effort. Based on innovative CERN-developed RoomSearchPlusSquaredRoot™️ technology, this innovative platform will allow you to carefully schedule your personal hygiene thus increasing your productivity and overall happiness.

Book your refreshing shower now!

For the technically inclined

The service’s infrastructure is based on CERN’s own PaaS hosting service, based on OpenShift. In order to cope with demand during high attendance hours, an autoscaling solution was put in place, which will increase the service’s capacity whenever needed. In a coming version, we expect to be able to use giant 3D printers to dynamically deploy (physical) shower containers at the Globe’s parking lot.

Indico 2.1 - feature summary

We’d like to give you a tour of the upcoming Indico 2.1. If you use Indico mainly to organize large conferences, we’re sure that you will particularly appreciate this release.

New Role System

Conferences often involve dozens of organizers with very different roles. It’s extremely important to make sure who does what and who is supposed to have access to different parts of an event. We would like to have an Indico where you can define exactly what each of the organizers will be able to do and do so to a reasonable level of details. This is why we are introducing a new role system and allowing fine-grained permissions to be assigned to roles, groups and users.

New Permission Widget

For now, you will find that the permissions we’re including are not yet as fine grained as they should, but we will be gradually adding new options over the next few releases.

Still, you will find that the “Protection” dialog will look a bit different. We’ve merged the manager, access control and submitter lists into a single one which offers you and immediate view over everyone who can access your event in any way.

Roles and Participants

The old “Roles” page has been renamed Participant Roles. Like before, it will list all persons who are somehow involved with the conference (e.g. as chairs, speakers or playing any other particular role) and now also their respective “custom” roles (as defined by you).

A new page, called Role Settings will actually list all the roles that exist in the conference and allow you to add, delete or modify existing roles.

New Abstract/Paper Question Types

One of the shortcomings of the abstract and paper reviewing modules has always been the fact that they’re limited to rating based on a scale. That is not the case anymore. From now on, you’ll be able to have yes/no and free text questions.

Importing Useful Data

One particular kind of request we often get comes from organizers who have registered their participants through a 3rd party system (sometimes belonging to a PCO - Professional Conference Organizer) and who would like to import their data into Indico. In order to help users in that situation, we have introduced a new Import from CSV feature for event registrations.

This feature currently only supports basic form fields (name, affiliation, position, phone number and e-mail) but we intend to extend it to to other field types in the future.

We have also implemented a mechanism that enables an organizer to import contributions, also from a CSV file, including time information.

Other Tools for Conference Organizers

We have implemented as well a few other tools that we are sure many of our users will appreciate:

  • Contribution cloning, which will allow you to easy replicate a contribution (e.g. with the aim of placing a copy in a different session);
  • Custom session types (until now there were only “Poster” and “Oral” options);
  • Private Abstract/Contribution types, which only you can assign;
  • Abstract Field visibility - decide who can see and edit your abstract fields;
  • New Abstract/Paper question types - you can now have yes/no questions and

We hope you will like this release. As usual, feel free to contact us if you have any comments/suggestions!

New Help Pages

One year ago we decided to disable our help documentation, since it was not up to date with the current status of the tool. The decision was taken based on the fact that Indico was going through a complete overhaul of its back-end, which implied significant interface changes every two or three months. It wasn't just worth rewriting the documentation every time.

At the beginning of this year, we started working on a new help site. We were lucky to count on the expertise of Maria Dimou, who invested a lot of time reframing a few parts so that they'd become more user-oriented and actually rewriting from scratch most of the rest, so that it would fit the "new" Indico. The result is now accessible and can be consulted through the "Help" link at the bottom of every Indico page.

We do have an additional surprise for our users, though: this new documentation is enriched with walkthrough videos that will explain you how to perform Indico's most used actions step by step. This is once again thanks to Maria's work, together with Alex Manzoni, a University of Geneva Master's student in Learning Technologies, who lent us his expertise (and his voice!) Many thanks to both of them for this great piece of work!

We hope that this new documentation will be useful to you. As usual, don't hesitate to let us know if you have any suggestions!

New Room Booking policy from 19 Apr

Following the new Room Booking policy defined by the Space Management Forum, we are applying the following changes in the Room Booking system:

  • Maximum total booking length of 1 year (already enforced);
  • "Booking groups" of rooms will no longer be taken into account (effective from the 19th April, 18:00 CEST);
  • The frequency of reminders for weekly and monthly bookings will be increased, with an e-mail being sent 1 week before each occurrence of the booking (effective from the 24th April, 18:00 CEST);

We will also make available, until the end of the month, a page explaining in detail the Room Booking process as well as the configuration options available to room owners.

New Paper Reviewing and Cloning interfaces

Indico keeps moving forward! The main focus of this release was the complete re-engineering of our Paper Reviewing module. The following list summarizes the new features and improvements that are included in the 1.9.10 release, one step before the long-awaited 2.0 release.

Submitting papers

Submitting a paper has never before been as easy and straightforward as it is now. Once the call for papers opens, users can submit their papers through the Call for Papers page of the conference:

Another entry point for submitting a paper for a contribution is the contribution page itself.

The paper submission form has also been simplified. Once the user submits their paper, it is marked as Submitted, the corresponding managers and reviewers are notified and the reviewing process begins.

Paper timeline

A new feature that we are very proud to announce is the paper timeline page. Submitters, reviewers, judges and managers can all access this page and be informed of the current status of the paper. Moreover, this page provides a timeline indicating all the steps that the paper went through until it reaches its final stage. Last but not least, this page also serves as a communication hub between submitters-judges and reviewers-judges by allowing comments for every paper revision submitted. Users can submit new revisions of their paper, reviewers can submit their reviews and comments and the judges can easily make a decision by having all the necessary information in one page.

1st revision 2nd revision

Reviewing papers

In the Reviewing Area of the conference, the reviewers can have a general overview of the papers that need to be reviewed and the reviewed ones.

Judging papers

Similarly to the Reviewing Area, the Judging Area of the conference provides an overview of the submitted papers to the judges. It lists the papers that the judge is assigned to, allowing them to make a decision but also to assign/unassign content and layout reviewers.

Call for Papers settings

Major changes also affected the management area of the paper reviewing feature. In the dashboard page of the Call for Papers, the manager can find available options and configuration settings, all grouped in a way to reduce complexity and improve discoverability. These include the activation of reviewing types (content, layout) and configuration of deadlines, the management of the paper templates, the configuration of the reviewing settings and teams and other necessary options.

In the reviewing settings dialog, one can manage the reviewing questions of each reviewing type, the announcement of the Call for Papers but also the email notification settings.

The interface for configuring the reviewing teams and the competences of each person is split into 2 dialogs. The competences dialog allows the manager to edit the competences of the reviewing team members quickly and easily:

Reviewing Teams Competences

Paper assignment

Apart from the Judging Area in the display area of the conference, managers can also assign papers to the corresponding reviewers and judges through the paper assignment page.

Paper email notifications

Yet another eye-candy is the new HTML layout of the emails sent through Indico related to the paper reviewing process.

Event cloning

The complex interface for cloning an event has now been simplified with our new step-by-step guide.

That’s all for now! We hope you will like the changes this release introduces and of course, we are looking forward to your feedback!

Full HTTPS from 5 Apr

After many years supporting both plain HTTP and HTTPS, we will be pulling the plug on unencrypted access to

The change should be transparent to all users. Services using the Indico HTTP API should switch to an HTTPS URL (should already be the case in most of them) or at least make sure their client code is correctly handling redirects.

For those who care about the technical details, this decision was made based on several factors:

  • The web seems to be moving in that direction;
  • Browser vendors seem to be embracing this change, some of them since quite some time;
  • Around 70% of our traffic is currently encrypted anyway, with most of the plain HTTP traffic coming from bots and crawlers;
  • Even though the HTTP2 standard doesn't make TLS a hard requirement, there is a high likelihood that many/most HTTP2 implementations won't even implement the non-encrypted version of the protocol;

New Abstract Reviewing module

The following list summarizes the new features and improvements included in the Indico 1.9.9 release. Improvements were done mostly regarding the abstract submission and abstract reviewing workflow. The new interface provides users with more intuitive features and give more flexibility to event managers.

Abstract submitted/withdrawn email notification

It is now possible to send email notification also when an abstract was submitted or withdrawn. There is also the possibility to choose from different email templates that can be used as a base for the email notification.

Global reviewers/conveners

A new concept of “global reviewers/conveners” was introduced. It allows managers to give global reviewing rights to selected users, allowing them not only to review abstracts of a selected track but to review abstracts in all tracks of the event. The distinction between reviewers and conveners is now also much clearer:

  • Reviewers provide an assessment of the abstract. They can consult only their own reviews.
  • Conveners can read all reviews in their tracks. If the event has been configured accordingly, they can also accept or reject abstracts on behalf of the event organizers/managers.

Exclude questions from abstract reviewing score

When configuring abstract reviewing questions, one can now add questions whose responses will not be included in the average of all scores of abstract reviews.

Submission, reviewing and judgment instructions

Very often organizers wish to provide specific instructions that should be read before an abstract is submitted, reviewed or judged. A new feature allows managers to provide a text that will be displayed whenever one of those actions is about to be performed.

Abstract submission announcement

When abstract submission is open, a nicely formatted message is displayed at the overview page of an event, notifying users that they can start submitting their abstracts.

“Call for Abstracts” page

The new integrated “Call for Abstract” page is a place where users can conveniently find all information regarding the abstract submission process, as well as a list of abstracts they’ve authored/submitted.

New Abstract timeline

The biggest addition in version 1.9.9 is probably the new visual representation of the abstract reviewing process. The timeline provides an easy overview of the abstract reviews as well as the overall score of the abstract.

Reviewers can easily add a review stating their opinion whether the abstract should be accepted, rejected, merged, marked as duplicate or moved to another track.

For judges (event managers) there is a review summary at the end of the timeline. This provides them with an overview that facilitates the decision process.

Reviewing area

Reviewers and conveners have now access to a new “reviewing area” where they can easily see in what tracks they are reviewers/conveners of, as well as how many abstracts they reviewed or still need to review.

Category and Event Management

Once again, a new version of Indico is released with a lot of user interface improvements especially (but not only) in category-related pages. This brings us one step closer to our Indico v2.0 destination! We are certain that these new changes will improve the way you interact with Indico and we are looking forward to your feedback. Let’s have a look!

Category logo

Categories can now have a logo which is displayed above the contents of the category.

Category events overview and calendar

In the process of improving the user experience on the category pages, the events overview page as well as the calendar page are becoming more and more friendly, following our users’ feedback.

Before After
Before After

Category navigation

One of the most frequent actions users perform on Indico is creating new events, as well as selecting a category where the event will be created. Navigation of Indico categories has been redesigned completely, providing a clean, fast and easy way to find a category. Try out the new search functionality: simply search using the category title and categories that match will show up. Note that your favourite categories will always appear at the top of the list.

Before After

Category management

Several improvements and simplifications took place in the category management area, allowing managers to create, configure, move and delete categories in a more efficient way.


By editing a category the manager enters the management area and specifically the Contents page where the list of subcategories/events is presented.

Before After


The Category Settings form has been moved to the standalone Settings page, using a modern form layout with an easy drag-and-drop functionality for uploading the category icon and logo:


In the same scope, the layout of the Protection page has also been improved, following the new UI standards.

Before After

Category-defined event headers

A new feature introduced in the Settings page of a category is the one of the custom event headers. This allows the display of a custom info/warning/danger message at the top of every event inside the specific category.


The actions of moving and deleting the current category are now always accessible from the icons right next to its title, in all category management pages. This new feature makes the old Tools page obsolete and thus it has been removed.

Moving categories/events

Moving the contents of a category (subcategories or events) has never been easier. From the Contents page, the manager has the options of moving a single or multiple categories/events to a new destination with only a few clicks. The interface for moving category contents reuses the aforementioned category navigator component inside a dialog for a consistent and beautiful layout

Before After

Something that shouldn’t go unmentioned is that users can move their events/categories from one category to another without the requirement of being the manager of the parent category. This means that if the user John Doe is the manager of an event in the category A, he can move it to category B without asking the manager of the category A to do this action for him.

Splitting category into 2 sub-categories

A new feature in the category management area is the one of splitting a category into 2 separate categories. More specifically, the manager can select a number of rows from the category’s contents and click on the split button located at the top right corner of the table. This will move the selected categories/events into the first new category and the rest into the second.

Meeting pages

Our main objective is to always satisfy the needs of our users and keep developing our software based on the feedback we get. The meeting page is one of the most common screens a user faces during their interaction with Indico and we put a lot of effort into polishing its interface and functionalities.

These are the most significant changes:

  • A very frequent problem during meetings is that the projectors cannot always display properly all color variations. We are now using darker tones with higher contrast to ensure that the meeting page will be displayed properly, independently of the screen type.
  • The consistent use of bold typefaces improves the readability and discoverability of the important items of the page.
  • Improvements in the visual hierarchy of the timetable entries came along with a better indentation of sub-contributions inside a contribution block.
  • The rendering of the break blocks and the edit buttons is now more discrete in order to retain the focus of the user to the rest of the timetable entries.
  • The clear separation between days helps the user track down the day of interest faster.
  • The attachment icon next to the list of uploaded materials has been removed, since the layout of the materials themselves is enough to distinguish them.
  • A new feature for this release is the option to get a direct link for a timetable block just by clicking next to the block’s title. You can then forward the link to a colleague and the page will open with focus on the selected block.

Event creation page

Another very common page for the managers of the events is the event creation page. You might have noticed that during the latest Indico releases the page started using some new user interface components, improving the way you select a location for the event, the selection of chairpersons, etc. Now, the event creation form appears in a beautiful compact dialog:

Before After

Performance improvements

A lot of things have also changed under the hood, as always. Being the focus of this release categories, all the operations related with them are now much faster.

The loading time of category contents in the management area used to be quite slow for categories with many events, since the whole list would be displayed. Now this list is paginated and the loading time will always be small.

Checking the calendar for big categories used to take ages: up to 1 minute for the Home category in our CERN Indico instance. Now, it’s instant!

The month category overview with contribution granularity was also painfully slow for big categories, usually ending in a timeout. It’s still a very expensive operation, but now the server won’t leave you hanging.

That’s all for now! We hope you will like the changes this release introduces and of course, we are looking forward to your feedback!

Discontinuation of Jabber server

CERN's Jabber server was created in 2009 in order to fulfil some use cases that other collaborative tools couldn't address. Its close integration with Indico meant that users could conduct their meetings over a chat session, or just complement their videoconferences with textual information.

Fast-forward to 2016 and conferencing tools such as Vidyo and Skype provide their own chat systems. Other services (such as Mattermost) have meanwhile been put in place to provide the same kind of functionality we were aiming for at the beginning. They do it in a more user-friendly way than even modern XMPP clients.

This is why the Jabber service will be discontinued from the 19th of September 2016 on, in favour of the options above. Indico integration will consequently switched off. You are encouraged to download any logs you want to preserve using the "Logs" button next to your room name ("Chat rooms" section).

Thank you for your understanding and hope to see you on Mattermost!

New Timetable styles, Contribution and Session management

We are pleased to announce yet another milestone in the path to Indico 2.0. You will find lots of improvements in this version, most of them related to timetable, contribution and session management.

Overhaul of meeting/lecture styles/themes

Meeting pages are the ones that receive the most visits. This is why we find it important to make them better version after version, adding new concepts to formulas that are already known to work. This time, we’ve focused on modernizing the look, taking advantage of new technologies and code to bring it to the next level. The most essential pieces of information concerning an event are now clearly isolated and displayed in a way that we hope that will decrease confusion while retaining simplicity.

Meeting styles

Better contribution management interface

Contribution management can be one of the most tedious tasks in conference organization. It often requires lots of clicks and transitions between pages. With this new release, we’ve tried to simplify this process as much as possible.

List contribs

Some of the actions that previously required changing page, such as setting a session or a track for a given contribution, are now within the reach of a click.


Filtering contributions based on their properties is now much easier, thanks to the user interface pattern that we had already introduced for Registration Forms in the previous release.


New session management interface

One of the completely new features we have added in this version is an interface fully dedicated to session management. The concept of “session” is central to Indico, yet the only way to manage a session up to now was through the timetable page. We believe things become much simpler when it is possible to have an overview of all existing event structures.

Session list

Modal dialogs

Modal dialogs are a very powerful tool when used at the right spots. We’ve tried to concentrate as much of the functionality as possible in the contribution and session lists and the remaining features in simple and easy to access dialogs.

Add Session

Better widgets

We have invested quite a lot of effort in completely reworking some of the most important widgets as to make them as usable as possible. For instance, we’ve added autocomplete to the room selector.

Room Widget

Managing authors and speakers is now much easier thanks to a new widget:

Authors Widget

Performance improvements

Thanks to our new PostgreSQL-based database schema, we’ve managed to considerably improve performance in some of the slowest spots in Indico, such as rendering of large meetings, conference timetables and overview pages such as “Today’s events” and Week’s events. In some cases, we’ve seen as much as 70% decrease in rendering time.

“CDS Agenda” style discontinued

The “CDS Agenda” style was introduced in the early days of Indico, in order to keep users of CDS Agenda comfortable during their transition to Indico. Ten years later, we have decided to discontinue it, as it is used by a very low number of recent events and offers no advantages over the “standard” Indico theme.

Other changes

Last but not the least, a series of small improvements that we hope will make a great difference in the daily work of some of our users:

  • You can now see who last updated a contribution’s minutes, as well as the modification time


  • We now display a link to the original event in every clone, as well as links from the original event to its copies. You will find this information in the management page, within the event header.


  • New “Export to XSLX” option - when CSV is not good enough (and Excel can be pretty picky sometimes!), we now offer direct export to XSLX format.

We believe that’s it! We hope you will like this release and, as usual, we would like to know your feedback!

Nov 3, 2015

IPython/Jupyter Notebooks

We're happy to announce that Indico now supports the rendering of Jupyter Notebooks (formerly known as IPython Notebooks). We believe this to be yet another important step in making Indico event more useful to our community.

Do you want to have a look? Try these two (public) notebooks uploaded by our users:

Otherwise, feel free to upload an *.ipynb file and try it out by yourself!

New registration form

Indico was conceived as the Swiss Army Knife of event organizers. Since 2004, we have contributed to the success of thousands of conferences and workshops around the world. In recent years, we have expanded our feature set, never forgetting Indico’s initial goal: to simplify basic operations in event organization and to make life easier for both organizers and participants.

A proof of this commitment with the organization of small and larger events alike is this new release that we have prepared for our users. It targets mostly the Registration Form feature, which until now was a exclusive feature of conference events.

More Registration Forms

The first big change is that Registration Forms are no longer exclusive to conference events. We have seen far too many cases of people wanting to couple the simplicity of a meeting layout with the flexibility of Indico’s registration form. We will keep moving in this direction, allowing people to use different configurations of building blocks.

Registration Feature

Although enabled by default in conferences and meetings, the registration feature can be used in lectures as well, if enabled from the Features dialog (Advanced Options). You will notice that the same is true for the Payment module, which we will mention below.

You can also now have more than one registration form per event. This especially useful if you require different information from different kinds of participants.

Registration Configuration

A single workflow that covers more ground

The equivalent of the Registration process in Indico meetings was, until now, the Participants feature, a lightweight equivalent that supported slightly different workflows. Over the years, we’ve realized that most features in both systems were actually complementary. This is why this new release includes a single, more complete registration workflow that aims at covering all use cases that were previously supported by two different modules.

Registration Configuration

This is why Registration Forms now support an invitation-based workflow as well as moderation. We hope this will allow organizers to have better control over who takes part in their events.

Registration Configuration

More options, less complexity

The old Registration Status feature helped organizers keep track of information that should not, in principle, be visible to users. It was just a simple list of tags, which was clearly not enough for the needs of some of our users. We’ve tried to solve this in a flexible and simple way: you can now create Administrative Sections, parts of the Registration Form that are not user visible but that can be set up with the same degree of flexibility.

Registration Configuration

Multi-option fields are now even more powerful. You can allow users to specify “+1” slots (useful for guests) and optionally charge them for it.

We have also simplified things by removing functionality that is easy to reproduce with the features we currently offer. This is the case of:

  • the Social Events section, which can be easily created using a “Multi-option” field;
  • the Sessions selector, which be, once again, can be done using a “Multi-option” field;

By default, you will now only see a “Personal Data” section, containing no more than title, first and last name, e-mail, affiliation, address and phone number. All fields, with the exception of first/last name and e-mail, can be disabled. That’s the bare minimum conference organizers need and any other fields/sections you need can be easily added.

A better (and faster) registrant list

Managing events with hundreds (or thousands) of participants is not easy, and we’ve been gradually trying to improve the performance and user experience of Indico in a way that larger volumes of participants are easier to manage. There’s certainly a lot of work to be done in that direction, but we’ve taken yet another important step: the List of Registrants is now faster than ever and includes a powerful filtering system that merges the old Apply filters and Columns to display functionalities.

Registration Configuration

Last but not the least…

We’ve been gradually trying to “tidy up” our menus. In the last release, you’ve already seen them reorganized. This time, we decided we would permanently move options that concern the event as a whole (Lock, Clone and Delete) to the Event actions bar. Lock and Clone were already there, but Delete has now joined them as well. They have also been removed from the Tools/Utilities page.

Registration Configuration

Since Delete is now easier to access, we’ve also made sure that the probability that people would accidentally delete any content (despite all the warnings) would be minimal. You will have to explicitly toggle a check box if you really want to do so.

Registration Configuration

The overall menu structure has also changed a little bit:

  • Advanced options now includes as well “Offline Copy” (which was a “Tool” before);
  • The old Services menu item has been renamed Logistics - this contains, for now, Webcast and Recording, but may be enriched with other services in the future;
  • Some advanced options have been moved to two new sections:
    • Services, containing everything related to collaborative tools and services that are not necessarily provided directly by Indico (Videoconference, Agreements, Logistics and Chat Rooms);
    • Reports, containing information about the event - Statistics, Logs and Lists of speakers, conveners, etc…

Thank you!

It’s been quite a long list of changes, but all of them have the sole purpose of making things simpler and easier to understand. We’re confident that this new release has succeeded in doing that, and we hope it will serve as a model for the next steps in this pathway to Indico 2.0.

As usual, we are looking forward to your feedback! Thanks for your time!

New event management interfaces

We're proud to announce a new update of Indico! We have worked hard to simplify some advanced feature that are nonetheless very important for our user community.

First of all, there is a new way to activate and deactivate Indico features. The new feature selector will simplify event management and leave complexity to power users. In the future, most Indico advanced features will be toggled in this way. For now, only a couple of them (Surveys and the Image Editor) can be managed.

The most important change in this release is a completely new version of the Survey feature (formely known as "Evaluation").

Many new things were added, such as the possibility of having more than one survey per event, support for "sections" and a drag and drop interface.

Conference organizers will be happy to know we have also added drag and drop support for the menu editor. The layout settings of conferences are also now much simpler to work with.

The "Image manager" has also been reworked. Dragging and dropping of image files is now supported, in the same way that it is already possible for materials.

Another new interface that the conference managers will enjoy is the event layout management page. Adding a conference logo, editting the colours of the conference page and the rest of the existing features have now been polished with a brand new design.

As you may have noticed in the above images, several pages in Indico, such as the event management page, room booking as well as the category management page, have received a new menu layout, grouping menu items together based on their type, for a better and easier navigation.

We hope you will like this new release. We will be back soon with new things!

Aug 20, 2015

PDF Preview now disabled by default

After careful consideration, we have decided to make previewing of PDFs from within Indico optional and disabled by default. This decision was taken after collecting all user feedback provided over the last few weeks. From now on, users who prefer to directly download materials can continue doing so just like before. No configuration change is needed.

The previewer will still be used for images, plain text and markdown files. And if you would like to use the previewer also for PDF files, you can still do so. Open your user profile, click on "preferences" and then toggle "Use previewer for PDF files".

Please note that, even if you have the previewer enabled, you can still directly download files, using either the middle mouse button, CTRL + click or ⌘ + click (on OSX).

Jul 21, 2015

New previewer feature

We are proud to present you our latest creation: the material previewer. This new feature allows you to quickly see the contents of a file that is stored in Indico without having to leave your browser. Just click on it, as you would do in order to download it. 


You can still download files just like before, using the "Download" button. Currently, the most popular image formats,  PDF, markdown and plain text files are supported.

We will be soon introducing support for new formats. Stay tuned!

Changes in "materials" and "minutes"

We are constantly reworking Indico, trying to make sure that event management is as easy and straightforward as possible. One of the points which we felt that could be improved was the management of materials - in the modern web, file management has to be simple and require as few clicks and dialogs as possible. We feel that Indico offers a very powerful material management interface, but one that could be easier for inexperienced users to understand - we decided then to work on its user-friendliness.

Material vs. Resources

One of the things that people learning how to use Indico used to struggle with was the concept of “Materials” vs. “Resources”. Materials were basically “types” of resources. We’ve always felt that this was confusing and not very user-oriented.

This is why in the new Indico version materials and resources are one and the same thing: they are files that can be attached to events, contributions and other Indico structures. Do you still need to group resources together? You can use a “folder”. A “folder” is just a container for files/links. By the way, don’t worry about your old materials - they have been automatically transformed into folders.

The material list has a new look. This should make things much easier to manage.

New material editor

The upload dialog

The old upload dialog offered a lot of functionality, which used to confuse users. We didn’t get rid of this functionality - you can still fine-tune things using the “edit” feature. However, we’ve decided to keep the dialog as minimalistic as possible.

New upload dialog

The “drag and drop” area is one of the things we are the most proud of. You can just drag files from your computer into it and it will just work. You can still do it the old way, by clicking “Choose from your computer”. You can also upload a file into a folder if you want.

Drag and drop in new upload dialog

The “Protected” switch lets you quickly specify whether other users should be able to open the file or not. By default, the protection level from the event/contribution/session will be inherited, but you can turn “Protected” on and restrict this further.

Materials and Minutes

You certainly remember that minutes used to be materials like anything else. Not any more. We now store minutes separately from event materials, which not only solves a series of technical issues but makes things easier to understand. Minutes can also now be consulted in-line in any event, and easily edited and downloaded.

Materials are also now displayed in a nicer way, already taking into account the changes mentioned above.

New meeting materials

New meeting minutes

New contribution minutes

New "reminders" interface

Alarms are now called "Reminders". We have re-organized the management interface. We hope you'll like it!

New user profile pages

A new version of Indico is now in production at CERN and with it many improvements. As it has been the case this year, most of the changes are happening in Indico's backend and aim at moving to a new and better performing data store.

However, as it has already happened in the past, we are deploying some nice interface improvements which we hope that will make your life easier and the application simpler to use.

It is with great pleasure that we present the new user profile page, which now includes the user dashboard.



Easily choose which fields you want to synchronise with CERN LDAP or set yourself:

Managing your e-mail addresses is not much simpler. Just choose which one you want to keep as primary.

Cleaner design, new collaborative tools interfaces

Design changes in event page

As you may have noticed there have been several visual improvements in the event pages of meetings, lectures and conferences. Namely, the following have been introduced in the overview page of the event :

  • a modern flat design

  • new icons and buttons

  • clear list of video conference rooms and chat rooms in the header of the event


Managing your video-conferencing rooms has never been easier. The interface is now cleaner and faster, for your convenience:


The old e-Agreement is now called Speaker Release and it can be found under the Agreements menu in the event management area:


The payment feature has been reworked, providing better usability for both managers and registrants. In the management area of a conference, the managers can see a list of the available payment methods, as badges, indicating the status of the payment method (enabled/disabled):

The registration page as well as the checkout page have been enhanced with a modern design for greater user experience, as depicted below:


The form to create requests for the Webcast or Recording of contributions is now placed under the Services menu in the management area and it comes with a cleaner interface:

Old events in Test Category being deleted

As announced by e-mail on the 15th of July to all affected event holders, events in the Test Category that are older than 6 months are being periodically deleted.

This measure aims to reduce the resources that are spent in storing old unused events as well as discouraging users from using the category for real events that should be instead placed somewhere else.

The policy is already officially in effect since two weeks, but only now these events are being actively removed. We expect that in a couple of days all events older than 6 months will have been deleted.

New branding, Room Booking Improvements

As you may have noticed, some things have change in Indico, mostly in terms of interface aesthetics.

New logo and header

We are proud to present you our new logo/header:

Indico Logo

Over the last few years, we have been gradually introducing small interface improvements. Step by step, we are creating a more modern Indico, with a friendlier look and feel. This new logo is only the first step - it's fresher and smoother, but doesn't break with its predecessor. We hope that you will agree!

Room Booking Module

Search Bookings

There are several interface improvements in the Room Booking interface. They are mostly related to user experience and we hope that they will make your life much easier:

  • Now, in My Bookings, you will see not only the bookings that you have created yourself, but also those that other people booked for you
  • The room booking process is now much simpler. There are fewer page transitions and the workflow has been simplified
  • Search bookings has been completely revamped. It's now much easier to use
  • My Pre-bookings has been merged into My Bookings. Now you can see both at the same time, no need to switch between options

API Changes

Those who are using our HTTP API, namely the Room Booking part, may want to have a look at the list of changes.

Technology Changes

You may have noticed that the Room Booking interface is much more responsive and response times are lower. This is because we are moving Indico to a more standard, better performant database system. For now, only this module has been affected, but others will follow over the coming months.

User Survey Results

Last November 2013 we have done a survey to collect feedback from our users, thank you all for your replies!

In the following document we have summarized the results of the survey and we would like to share them with you: Indico survey results.

This survey allowed us to collect many findings and ideas on how to improve Indico. We have already implemented some in the last releases and more changes will come in the future.

Thanks once again!

New HTTP API Access Key policy

Indico provides an HTTP API that allows anybody to export Indico data into many different formats. Up to now, an API Key was mandatory in order to query Indico's database, whether requesting public information or restricted content.

From now on, that API Key will not be required anymore to export data related to public events. On the other hand, it will still be mandatory when exporting restricted data, as well as the corresponding signature based on the user's secret key.

Users do not need to apply any change to their scripts, everything will continue working as usual.

We hope this change will make life easier for many of our API users, who need to fetch information from Indico and disseminate it through different media.

New Registration Form, Abstracts and more

Rich Abstract Editor

We are proud to present the new Abstract Form which provides content editors that support Markdown and LaTeX. Authors will write their abstracts in Indico, including LaTeX formulas, and they will see a live preview in a panel just below the editor. Of course, all the PDFs generated by Indico will also render Markdown and LaTeX.

New Category Browsing Interface

Brand new Registration Form Edition

The registration form is one of the most used modules but edition was not simple in the former versions of Indico. We have developed a very intuitive and simple interface to edit and create registration forms, simply using drag&drop and inline editing. Learn more from here.

New Category Browsing InterfaceNew Category Browsing Interface

E-Ticket for Conference Attendees

This new module will enable the generation of e-tickets for each participant of the event. Each e-ticket is a PDF with basic information and a QR code. This QR code can be scanned at the Registration Desk in order to check the participant in. How to scan that QR code? You can simply use our new mobile app Indico Check-in (download it from here). Learn more about this module from here.

New Category Browsing Interface

Offline website creation

This old folk of Indico has come back to stay. It can be found in the tools section of every event and it provides the option to request an offline version of your event. This means that all organisers can download to their computer their events and navigate them offline. They can even browse the uploaded files without Internet Connection!

New Category Browsing Interface

More in Dashboard

Indico is trying to help you find the events that you might be interested in. That is way that you will now see, in your Dashboard, a list of categories you might be interested in. If you find any of them interesting, add them to your favourites! Check it out right now from your dashboard.

Vidyo News

  • Vidyo Search: From now on, one does not need to create a new Vidyo Room for each meeting. You can simply search for your own Vidyo rooms and attach them to your event.
  • Access and Moderator PINs: From now on, the acess and moderator PINs that one can define for a Vidyo Room are masked for security reasons and cannot be displayed on the event page. Moderators can always reset the defined PIN, but need themselves to distribute the PIN among the relevant participants.


  • New URLs: take a quick look at your browser's URL bar. Indico URLs are now beautiful and short!
  • Extra configuration parameters can be found in the Conference/Layout/Menu/Timetable option. Conference organisers can choose if the timetable will be rendered by default using the regular or detailed view, and if it should use the normal or 'by room' layout.
  • We have also added a new extra field type to the Abstract Form: dropdown menus can now be added to the form as an extra option.
  • User search will ignore accents from now on. No more problems when searching for "González" since it will find the same results as "Gonzalez".

Interface improvements - Mobile, Dashboard and Room Booking

Indico Mobile

We are proud to present the new mobile version of Indico. Now, whenever you connect to Indico from a mobile device, you will be able to choose whether you want to use the traditional interface or a simpler mobile-friendly version.

Mobile Indico Interface Switch

Brand new category browsing interface

The category browsing interface has now a much fresher look, and a layout that better adapts to tablets and other devices with smaller screens.

New Category Browsing Interface

Favorites and Dashboard

Now you can have "favorite categories" - categories that you want to follow. Just click on the button at the corner of the page, and the category in question will be added to your list. Then, from your Dashboard ("My profile" link in the blue bar), you will be able to see what is going on in your favorite categories. The Dashboard also allows you to know which events you are taking part in.

Favorite Categories Dashboard

New Room Booking interface

Booking a room has never been easier. Based on the feedback we got from our users and standard usability practices, we have come up with an interface that is simpler and more efficient. You can now search for rooms as you write and check the availability of more than one room at the same time. This is still a quite experimental interface, so, don't hesitate to send us your feedback on it.

New Room Booking interface

New Event Log interface

We have also thought about event managers in particular. One of the interfaces that had for a long time been waiting for improvement was the event log. Now, if you click the "Logs" link from any event's management area, you will be shown a clean and functional interface that allows you to quickly get to know what has been happening with your event.

New event log

Other improvements

But there are many other things you will be able to find out for yourself. Among which:

  • Lectures - Added functionality to grant Submission Rights to Speakers
  • Paper Reviewing - Granted Paper Review managers, referees and reviewers permission to upload papers on behalf of the author
  • Room Booking - Added option to change room after cloning a reservation

Statistics, protection & others

A new version of Indico is now available at CERN.

Please note that our policy concerning iCal/Atom feeds has changed - before, downloaded iCal/RSS files included all events, even those protected (except for categories inside ATLAS). Now, users will only get back the events that they are authorized to access. If you want to have an iCal/Atom file that contains events that are private (and that you can access), you'll have to log in first. If you wish to retrieve this information without having to log in (i.e. using an automatic system), consider using our HTTP API.

This new release includes, among others, the following features:

  • Indico now collects access statistics per event/contribution - you will be able to see them for events managed by you - please note that statistics have only started to be collected from the moment this upgrade has been performed, you won't get any numbers for previous dates;

    Statistics page

  • Protection status is now displayed for events and categories - it is now shown at the top of each page, next to timezone information;

    Protection status

  • A new unified user information pop-up has been added - it includes basic profile options;

    New search box

  • Reworked Search Box - it now allows you to set whether you want to search in the current category or at the server level;

    New search box

  • Contributions and abstracts are now displayed in a much nicer way - you can now filter them by title;

    Contribution list Individual contribution

  • Review history in paper reviewing has been improved;

  • Atom is now used instead of RSS for feeds;

Indico survey results

Last summer we have done a survey to collect feedback from our users, thank you all for your replies!

In the following document we have summarized the results of the survey and we would like to share them with you: Indico survey results.

This survey, as well as a simple heuristic evaluation and usability lab test sessions done in parallel, allowed us to collect many findings and ideas on how to improve Indico. We have already implemented some in the last releases and more changes will come in the next few months.

Thanks once again!

Timetable Drag&Drop and more

New features and improvements have been added to Indico, such as:

  • Timetable Drag&Drop: The edition of your event timetable is easier now. Simply, drag and drop the timetable entries in order to change their start date. One can also resize the timetable entries, move contributions inside sessions and undo the last change. Learn more here.
  • Renewed participant module: This module has been changed from the core to the interface. It is easier to use and setup. You can also customize all the e-mails. Learn more here
  • User search: All modules that provide a search for users are now opening a fast search pop-up with "favourites" capabilities.
  • New pop-up dialogs: All Indico pop-up dialogs have been improved in order to perform better with all browsers. They can be dragged around the webpage and they can be closed using ESC key.

New Social Network Pop-up

In line with the growing adoption of social networks by our users, we have introduced a new feature that allows Indico users to share Indico events using different social web sites.
This button is conveniently located at the bottom right corner of every Indico event page:

social button

When triggered it opens a pop-up which allows the content of the page to be immediately shared using any of the supported services.

social pop-up

We currently support:

It is as well possible to directly import the event to Google calendar, just with a click.

Please note that the event data in Google Calendar won't be updated in case it changes. If you want that to happen, you should manually import the event's iCal file into Google Calendar.

Export API, E-payment fees and more

We are glad to announce new features and improvements on Indico v0.98b2, such as:

  • HTTP Export API: Indico allows you to programmatically access the content of its database by exposing various information like category contents, events, room and room bookings through a web service. You can also access protected information using an access control service. Learn more here.
  • E-payment extra fee: Conference organisers can setup extra fees for credit card payments. For instance, one can choose to charge extra 4 CHF with VISA, MasterCard, etc. Check it out in your conference, Registration > E-payment > CERN E-payment. 
  • Electronic agreement: when requesting a webcast or recording for your event, there is no need for authors to sign a paper agreement anymore. Now this is done electronically throug Indico. Learn more here.
  • Contact info: Category managers owning protected categories can set contact details to be used in case of an Access Error. In such a case, a user that cannot access (and he should) will know who to contact.
  • Automatic profile update: Your personal data is automatically updated with the information from CERN database. If you want to keep a different Indico profile you can now edit it and avoid the synchrozation.
  • Map of rooms: The map of rooms has become the home page of the room booking system.
  • Importer: Indico Timetable has a new feature Import. This tool can be used to fetch information from CDS and attach it to your event timetable. Learn more here.
  • Room blocking: If you are a room manager and you need to prevent bookings during a given period for a set of rooms, this is your feature. Block a room for any period of time and nobody but you will be able to create bookings. Learn more here.
