Dear Jeremy Thank you for your comments [1,ISSUE-176]: * Relationship between skos:exactMatch, skos:broadMatch and skos:narrowMatch. The Working group consider that there is insufficient implementation experience or evidence to be able to make a firm decision (see resolution of ISSUE 75). The current situation is that there are no axioms stating relationships between skos:exactMatch, skos:broadMatch and skos:narrowMatch. Axioms could be stated, for example, asserting that the composition of skos:broadMatch and skos:exactMatch is a subproperty of skos:broadMatch. Note that this would, however, require OWL 2 features which are not present in OWL. Since several constraints that cannot be expressed in OWL1 have already been included, I see no harm in including further constraints that cannot be expressed in OWL1. These should be expressed in plain text, like for example, S14, and any reference to OWL2 should be clearly informative and not normative. ------------------------------------------------------------- The intended reading of this statement is not that axioms have been left unstated due to them requiring OWL 2 features, rather that the WG felt unable to make a clear decision as to whether such axioms should be stated /in any form/ (for example as prose). We propose to *postpone* this issue, with no change to the document. Is this acceptable? Cheers, Sean Bechhofer Alistair Miles [ISSUE-176] http://www.w3.org/2006/07/SWD/track/issues/176 [1] http://lists.w3.org/Archives/Public/public-swd-wg/2008Oct/0077.html -- Sean Bechhofer School of Computer Science University of Manchester sean.bechhofer@manchester.ac.uk http://www.cs.manchester.ac.uk/people/bechhofer
