Re: Semantic Web archaeology

I'm probably being too sensitive but I just don't want to go around saying
who is or is not in a particular group. There is going to be a broad
spectrum of ideas, opinions and knowledge. I would like to see semantic web
technologies be as inclusive and inviting to newcomers as possible and
don't want to see "outsider" become a synonym for "noob".

I recall this issue coming up in WG discussions early on in the WG activity, and it being dismissed as unimportant.

The notion of a formal model separate from the XML rendering didn't really solidify until the 2004 round - I recall there were some constructs from the 1999 spec that had to be dropped because they didn't really have abstract-model representation, but were grounded in XML structures.  E.g. there was an "aboutEach" property that could be used to generate statements about the contents of a container: for this to work, the container was very much part of the underlying assumed model.
