Feedlists etc in RDF, using Atom/APP?

[Danny Ayers]

I'd welcome a bit of advice relating to how to do blogrolls, archives,
category trees, feedlists etc in RDF/XML. I had a crack at it the
other day [1], the example I've pasted below. I'd made up some new
terms, but I got a comment from Rick Thomas suggesting using Atom as a
starting point for the vocabulary (i.e. an Atom/OWL kind of thing). I
reckon this makes a lot of sense, given that the immediate use cases
are in the same domain.

Anyhow, specific questions are whether app:collection might make a
good replacement for Directory below (are collections ordered?
nestable (by reference?)), whether there's anything suitable instead
of Resource (I keep coming back to rdf:Resource being the best
bet...), whether a non-RDF/XML syntax (with GRDDLability) might be a
better approach..?
Any suggestions appreciated.

Cheers,
Danny.
