Re: F2F Decision: Multiple Resources

Regarding (1), we were waiting for any feedback from the list before
writing up a new draft :)

Currently we don't have collections of annotations as in scope for the
current work.  That said, we certainly can't prevent oa:Set (etc) from
being used with annotations as the object of item, as any resource
must be able to be put there.

And for (3), the idea was to have a resource that was both an oa:List
and an rdf:List. Then if future RDF versions have a better way of
dealing with ordering, then we would not lose our own List class, but
inherit the new version.
