The CS3 apis are all about files. Large parts of it focus on how to make files accessible to users. But once users have access to a file, they want to do something with them. Therefore external applications bring a real value to an EFSS solution. The solution on how applications can integrate themselves in the CS3 ecosystem is called App Provider ("cs3.app.provider").

Since the last CS3 conference, the possibilities for external applications have been improved or added in the CS3 apis, REVA and ownCloud Web.

This progress on the App Provider and how you can use it today will be demoed in this session..
