ISSUE-176: Last Call Comment: Mapping vocabulary constraints

http://www.w3.org/2006/07/SWD/track/issues/176

Raised by: Sean Bechhofer
On product: SKOS

Raised by Jeremy Carroll in [1]:

    * 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.
