At the telecon last night, I (successfully) requested a weakening of the proposal for first publication, to leave it open as to whether the RDF Mapping doc would be included or not. This was not an attempt to immediately advocate that it should not be included; merely an attempt to leave it open to advocate that it should not be included. My motivation for doing this was that in an HP internal reviews of all three documents, the reviewer had minor issues with the other two docs but had more major issues with RDF Mappping. Before advocacy one way or another, I will need to refresh my memory: looking at both the most recent version of RDF Mapping, and the HP internal review. If I remember correctly the heart of the criticism was that: a) The OWL 1.1 suite of docs, do not include an OWL Full semantics. HP regard an OWL Full semantics as critical. b) In OWL 1.0, the tension between the OWL Full semantics and the direct semantics is resolved in cleverly non-deterministic mapping rules c) The OWL 1.1 mapping rules, probably in order to simplify life for the implementers, have reduced the non-determinism (and the cleverness) d) In the HP reviewer's opinion the reduction in the non-determinism severely impacted the ability to define an appropriate OWL 1.1 Full semantics. In my view, if this criticism stands, then, it is a criticism of the whole document, rather than of a few paragraps or sections. It also reflects a value judgement that OWL Full semantic compatibility is more important than simplifying life for the implementors of the mapping rules, even at the risk of being too clever by half. Jeremy (carefully sketching a position that I might hold later, or some anonymous HP reviewer might hold; without actually committing to it!)
