Last Call Comment: SKOS Notations and Datatypes

State:

Description:
From Peter Patel-Schneider [1]:

One portion of SKOS (Notations) uses custom datatypes.  Although these
seem to be benign, because RDF and OWL allow extra datatypes, the use of
these datatypes is not likely to be supported by many tools.  The
presence of extra datatypes is likely to cause difficulties in some
tools, which may just reject SKOS documents that have these datatypes.

2008-11-10: RESOLUTION: With respect to your comment regarding extra datatypes, the OWL Ontology reference document [3] states: [[ Tools may vary in terms of support for datatype reasoning. As a minimum, tools must support datatype reasoning for the XML Schema datatypes xsd:string and xsd:integer. OWL Full tools must also support rdf:XMLLiteral. For unsupported datatypes, lexically identical literals should be considered equal, whereas lexically different literals would not be known to be either equal or unequal. Unrecognized datatypes should be treated in the same way as unsupported datatypes. ]] Thus we would not expect applications to *reject* SKOS documents containing unsupported datatypes. The Working Group propose to make no change to the document in response to this comment and close this issue.
