Yep - every property in the hnews vocab has a domain of atomowl:Entry.

RFC 4287 can be found in hundreds of locations, including:

http://www.ietf.org/rfc/rfc4287.txt

Yep - pretty much the same concept.

It would certainly be possible to add an extra class to the hnews vocab
to cover the concept of a news item, but it's unclear how this would be
helpful, as the concept of a news item is pretty vague anyway. Do blog
entries count as news? Tweets? Wiki updates?

I use <http://creativecommons.org/ns#license> to cover licenses.
