CERNBox is key enabler service for users at CERN and beyond. The service is used by more than 37K users and stores over 15PB of data, representing all the user communities at the laboratory.
In this talk we will explain the current status of the service, the challenges we faced in 2021 and we look into the future: CERNBox as the gateway for heterogeneous storage spaces at CERN and beyond.

Sunet is currently establishing Sunet Drive as their solution to store and share large amounts of scientific data. The architecture is based on a global scale setup of Nextcloud, where each university and college gets an own node, which then can be customized. The underlying storage infrastructure is based on S3 containers, and each university can manage and assign new buckets depending on...

Since a few years SURF has been running a sync-and-share service called Research Drive next to the personal storage based SURFdrive. Research Drive is specially tailored for the special needs of researchers. These special needs had to do with flexible quota, project-based storage rather than personal storage and multiple means of authentication. The latter was an absolute necessity in order to...

The Invitation workflow is one of the elementary scenario on how to enable file sharing among users from different EFSS systems. Invitation workflow eliminates the necessity of knowing the exact identity of the user (share receiver) in the target EFSS system. You can generate a share invitation and distribute it via email or distribute the link via any other channel, chat app, etc. The target...

Reva implements the share-with workflow and the invitation workflow.

OCM assumes the sender of a share is a specific user.
But in some situations it would be useful to think of
shares as owned by a group. Would this be a feature
we could add to OCM? What would be needed? What issues
can we foresee?See also https://github.com/cs3org/OCM-API/issues/53

When working on the spaces feature we reorganized reva's internal path semantics. While the current global path based namespace looks efficient, it ties namespace organization to a single instance. This prevents true federation. By replacing absolute paths with relative paths and a corresponding root we can delegate building a user individual namespace to the clients. This allows them to...
