RE: SKOS Core review Re: issue: non-Literal "comment" properties Re: new draft of SKOS Core guide

Just some food for thought:

I know that it's perfectly legal in non-DL RDFS space to
have hybrid properties, but given that e.g. dc:creator
has already caused a lot of confusion and needs rules
or application-specific extensions to be processed
without problems, wouldn't it make sense to separate
datatype props from object props or to limit certain
documentation props to literals? RDFS works quite fine
with rdfs:comment and rdfs:seeAlso, maybe SKOS could
live without hybrid props as well? That would at least
be helpful for tool developers who try to extend their
ontology tools (both editors and browsers) to support
SKOS, and OWL DLers would probably be happier, too.
(I'm not sure for example if protege's OWL plug-in
supports rdf:Properties that are not typed as either
datatype or object property..)

sorry if this has already been discussed and resolved.


regards,
benjamin
