Sakai 3 export/import formats research

Since Sakai 3 is a ground-up rewrite, there is plenty of opportunities to rethink assumptions that have accumulated over the years.  One of those areas where a fresh look should do some good is in course export/import formats.  Sakai 2 has its own proprietary format which provides a “full fidelity” capability to move from one course site to another without losing anything.  While not losing anything is desirable, it comes at quite a cost; i.e. not being compatible with anything else on the planet.  This approach is not uncommon and I see now that Moodle also has its own proprietary format.

While there are some good open standards for course export/import (e.g. IMS Common Cartridge or SCORM), they will not provide a “full fidelity” export/import workflow where one could export from Sakai 2 and then import into Sakai 3; i.e. some information would get lost in the translation.  Now, supporting these open standards would have other important benefits, they are not first order solutions for simply getting from Sakai 2->3.  My hopes are that one day an open standard could be expressive enough to cover such a use case, but the innovation curve in the applications and tools may always exceed the ability of a lowest common denominator solution.

With that said, we thought it would be beneficial to see if Moodle’s export/import format provided enough capability to move data from Sakai 2->3 without losing any critical structure.  If this worked out, we would have one great feature out-of-the-box: the ability to move from a course from Moodle to Sakai and vice-versa.  It will be interesting to see how this works out and I will keep you updated as progress is made…
