Re: To use or not to use recommended metadata in a W3C ontology ?

Phil's point about use of some is relevant - go ahead and use annotation
properties where we think they add value, rather than re-invent these
wheels (as per use of skos:example) , but justify it against W3C precedents
.

Not suggesting this (for or against), but important to note for
completeness...

There is another option here of course, which is to provide metadata
modules for different vocabularies - i.e. a file with all the metadata
required for LOV

This can then be made discoverable multiple ways, according to the
architecture of the Web (and the capability of the discovery platform):
1) explicit registration (tell LOV by uploading a ref to the metadata )
2) the pattern used for robots.txt - external systems look for a relevant
metadata pattern (was also proposed for VoiD)
3) imported from the normative sosa.rdf doc (nasty...)
4) content negotiation using profiles
5) IRI hacking - eg adding an underscore to the object local name as per
some UK gov practices.

(this is all a bit ugly - but thats a bigger question)

The point is, if we think the vocabulary does not have a precedent of being
used in W3C context, but meets a need, then we can publish a separate
informative artefact and manage the "placeholder" feel of it.
