What is FileSet a subClassOf ? directly to ore:Aggregation, or off of pcdm:Object?

It should be a subclass of ore:Aggregation

Then needs definition at the abstract level as to what sorts of metadata it can have. Can it have both technical and descriptive, or only one and if so which?

I think the key metadata is how the FileSet differs from other FileSets attached to the same Object — this could be creation date, or some (TBD) vocabulary to express which one is preferred or textual/visual/etc. format or something else. I think I would categorize that as technical metadata, since the purpose is to decide which FileSet to use in a given situation.

Also digitization (or capture) date/event information, which I'd also say falls mostly under technical. But I agree, we need to scope out Fileset as a class a bit more. (Sorry to jump in)

The case I keep coming back to is a FileSet that represents an act of digitization, and is used to group the files that derive from that digitization event. I would like to record the technician or vendor who did the digitizing, and the date it was done as metadata on the FileSet. Would that stiill be considered technical metadata or could one use something like dc:creator?
