There's no reason why you can't mark an object that you fish out of an
annotation with IAttributeAnnotatable and then annotate that. However, this
feels suspiciously like you're asking the wrong kind question. :)

Can you explain (a) what you are trying to store (what is a "feed" in this
case? is it just feed-specific metadata? or an actual list of items rendered
to RDF?) and (b) what you need UUIDs for and (c) when you need to use the
UUIDS?
