Earlier this year, I was on a quest to hook a FEDORA content repository into the Sakai collaboration and learning environment. What looked at first to be a fairly easy integration turned out to be and I set the project aside for another time. Today brings word from Ian Boston of a JSR-170 implementation in Sakai:
During the Summer of 2006, I did a JSR-170 Implementation of ContentHostingService as a prototype against the then Trunk 2.2 ContentHostingService. The implementation took the ContentHostingService API and re-implemented it using JSR-170 under the covers. It was done in in such a way as to allow JSR-170 clients (eg WebDAV implementations) to use the JSR-170 API directly and still obey the Sakai AuthZ implementation.
