Architecture
The Collaboratory is composed of an ecosystem of Open Source solutions.
Each solution is specialised in different domains of collaboration:

XWiki

XWiki stands for eXtensible Wiki. It is a specialised Open Source wiki platform for collaborative work on documentation.
Its architecture is meant for extensibility: applications can be developed directly in the wiki.
It is the main component of the Collaboratory. This is where you are now, and where you can create, manage and visit collabs.

KeyCloak is an Open Source Identity and Access Management system.
It is what you see when you log in an application of the Collaboratory ecosystem or when you navigate to your profile and click on 'Edit my profile'.
Its purpose is to manage and protect your identity and the one of all the users, handle authentication for the different application of the Collaboratory ecosystem and centralise the permissions.
