10. The Apereo Foundation
The University is a member of the Apereo Foundation. As members, Oxford University staff are entitled to a number of benefits including a reduced rate for attending the annual conference. The Apereo Foundation host a number of educational software products (including Sakai), publish a regular Sakai newsletter and administer a YouTube video channel.
The universities of Oxford, Hull and Cambridge use it as their institutional VLE. It is widely used at Lancaster, Newcastle, Bath and STFC (Daresbury) as either a VLE or a VRE (Virtual Research Environment).
