Yes! We discussed the various Goals in the Digital Objects Cluster discussion last night. I think it's really useful to think about the goals of each use case, and to come up with shared terminology.

This is based on the thought that of the 40+ use cases, we will likely need to collapse to fewer than 10 for the end report. I'm hoping we won't lose any of the important points (though this will be challenging).

Our cluster is continuing to discuss the taxonomy that Mark devised:

You're most welcome to join in the discussion and editing.

Common resources include subject classifications which are used to classify courses/modules, publications, A/V material and othes, which are expressed in SKOS and mapped to each other. We expect resources such as people, courses, topics and publications to play a central role in connecting Open University datasets to each other, and to external resources.
