The first half of this week I spent with Chris at MIT sitting in on the DSpace 2.0 architecture design meeting. In this session, they were focused primarily on determining the high-level services necessary to support the next version of DSpace.
- One discussion which we returned to several times was the idea that there is fundamental set of services needed by any repository which could be constructed in a layered structure. Chris posted an initial write-up of these ideas.
- Another discussion that Chris and I had on the side with Richard Rodgers was that the notification capabilities of both Fedora and DSpace present a way to coordinate the content available in each system. An example of this could be to allow both Fedora and DSpace to store content in the same location (such as on Amazon S3), then use update notifications to create/update/delete the object model. This gets around the need to have a shared data model in order to share content.
The last half of the week was spent finishing up tasks prior to the 3.1 release.
- Completed and merged FCREPO-245, which allows GSearch (and any other user of the MessagingClient) to start up prior to the messaging provider being available. This was primarily an issue when Fedora and GSearch were running in the same server and GSearch was started first.
- Completed and started review of FCREPO-241, which provides authentication filtering for the REST API relative to the authentication settings of API-A and API-M.
