Hi Mark,

Sorry for the lag.
But--lo and behold!-- I'm going now to try and play my shepherd role, and react to your mail.

I think the P20 case really has aggregation of resources high on its agenda: there are "folders" (but they already exist prior to the use case) and even, serving aggregations of search results is mentioned) so I think it should mention ASSOCIATE--or at least RELATE-- (in your new terminology at [2]) somewhere.

I think you captured 1 and 3 properly. 2 is more orentied towards the production of data. As said, they want to prepare new digital editions of texts, new "Manifestations (in FRBR terms)". The description then mentions "related items" and "authority data" as two specific foci. I would thus categorize this second goal aspect using REUSE-VALUE-VOCABS and ASSOCIATE from [2].

Hoping this is useful,

Antoine

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.
