It's still pretty much in flux, but to give you an idea of what we've been looking at, the current version of the Atom/OWL ontology is at [1], some instance examples towards the top of [2]. One significant difference between the approach here and previous RSS/Atom-in-RDF efforts is that the versioning of entries is explicitly modelled. If you did a blog post today and tomorrow reposted it correcting a spelling mistake, both versions could coexist in the target store (same id, different updated, different content). This should fit better with the Semantic Web world view, but does lead to some complications, not least in keeping consistent with the Atom spec (and its naming scheme). Cheers, Danny.
