Re: RDF Update Feeds

At the Library of Congress we've been experimenting with using an Atom
feed to alert subscribers to new resources available at id.loc.gov
[1]. The approach is similar to what Niklas' is doing, although we
kind of independently arrived at this approach (which was nice to
discover).

Creates, updates and deletes happen on a weekly basis, so it's
important for us to let interested parties know what has changed. We
ended up using Atom Tombstones [2] for representing the deletes. And
Atom Feed Paging and Archiving (RFC 5005) [3]  to allow clients to
drill backwards through time.

I just noticed Link Relations for Simple Version Navigation [4] get
announced on an Atom related discussion list, which looks like it
could be useful as well, if you maintain a version history.

I'd be interested in any feedback anyone has about using this approach.
