The requirement to login to InDiCo before registering has now been disabled due to some participants experiencing problems. In order to register for the workshop you now simply need to fill out the workshop registration form. Any changes you wish to be made to your registration details should be sent to OAI4-Organisation@cern.ch. You may still login to InDiCo first (click on the login link in the top right-hand corner of the screen, from where you will be prompted to login or create an InDiCo account) before filling out the workshop registration which will enable you to modify your own registration details. Your name, institution and country will be used on your participant badge. Email addresses will be used for communication about this and future events only and will not be made public. However, a list of registrants including email addresses will be distributed to participants at registration. Please indicate whether you wish to attend a tutorial. When places are filled, this option will be removed. We will keep a small waiting list in case of cancellations. You will receive a copy of your booking information by email on successful completion of the registration form The cost of attending is 200CHF which should be paid on arrival at CERN.
