Is there an RDF ontology for blogs?

Question

I'm setting up a blog, and I'm fascinated by RDF and the idea of the sematic web. I'd like to use RDFa to embed sematic data into my blog. There are several well know semantic web ontologies like FOAF for decribing people, ical for events, geo for places.

Is there an ontology for blogs? Something to say "This site is a blog. Foo is a blog entry. Foo was posted on (date here in ical or whatever), foo has X comments. Y is a comment on Foo. Y was left at (this time), Y was left by (someone)"?

Update: I know about Dublin Core, that seems to cover a lot of stuff I want (e.g. "This was written at this time", "This was written by this person", "The title of this is whatever"). So that's goes about 75% of the way there. Is there anything that fully marks up blogs? Takes it to the next level? "This is a blog", "This is a comment on this entry", "This is the URL for a trackback on this blog", etc? If not I'll just make my own.

Answer 1

the SIOC ontology might be what you are looking for. its purpose is to express information about blogs, forums, wikis and other kinds of social media sites.
