Re: Contributions and Supersedes

Hi Paul,
I think that all of us got the mail. At least I did :)
It is curious, because we had some discussions about the prov:generated in
the prov-o group.
We didn't include it in the ontology because it allowed activities
"pointing to the future", and some
people disagreed with that.

Best,
Daniel
