Re: PROV-ISSUE-72 (DGarijo): Uses should be renamed as used [Formal Model]

Hi Ralph,
your diagram is very similar (if not the same) to the one we created when we
started to discuss
the provenance ontology model, several weeks ago:
http://www.w3.org/2011/prov/wiki/images/a/ad/GlobalSchema.png,
http://www.w3.org/2011/prov/wiki/images/8/80/InitialDiagram.png (there have
been
some renaming of properties on the hierarchy, so it is a bit out of date).

However, after some discussion, we have realised that it is not the best
approach
to model some of the n-ary relationships of the model (like used/uses).

In the next link you can see the current state of the ontology.
http://www.w3.org/2011/prov/wiki/PIL_OWL_Ontology

If you wish to contribute or add feedback you are welcome to edit the wiki.
I think
it is better to reach consensus over there rather to bring up new custom
implementations
each time, don't you think?

Best,
Daniel
