Hi All,
Any guidance on using predicates in linked data / rdf which do not come
from rdfs/owl. Specifically I'm considering the range of:
http://www.iana.org/assignments/relation/*
Can't find a URL that resolves there
snap; but that's what rel="edit" and so forth resolves to.
see example:
http://www.w3.org/2001/tag/doc/selfDescribingDocuments.html#ATOMSection
and quote:
"If the relation-type is a relative URI, its base URI MUST be
considered to be "http://www.iana.org/assignments/relation/";
http://tools.ietf.org/id/draft-nottingham-http-link-header-03.txt
obviously all the links defined by:
http://www.iana.org/assignments/link-relations/link-relations.xhtml
(from the atom rfc)
such as edit, self, related etc - with additional consideration to the
thought that these will end up in rdf via RDFa/grddl etc v soon if not
already.
Any guidance?
By using something as a predicate you are making statements about it. But...
If you can find IANA terms like this, please use them - though beware
the page isn't the concept. You might have to map them over to your
own namespace, PURL URIs preferred.
Would it make sense to knock up an ontology for all the standard
link-relations and sameAs them through to the iana uri's?
Best, Nathan
Don't use "sameAs", this is where owl:equivalentClass and
owl:equivalentProperty come in handy.
