For how little this matters really - i'd really advice anyone wanting
to produce RDFa of schema to live with it and use direct
http://schema.org uris as per their example in RDFa.

i would seriously advice against using triples with http://schema.rdfs.org
.
That would be totally and entirely validating their claim that either
you impose things or fragmentation will distroy everything and that
talking to the community is a waste of time.

Would it be reasonable to use http://schema.rdfs.org rather than
http://schema.org in the URIs? Essentially mirror what one might hope
for schema.org to become. Then if it does become that, link the two
together?

What makes you so sure about that not one day in the (near?)
future the
Schema.org URIs will serve RDF or JSON, FWIW, additionally to
HTML? ;)

Hi all
Something I don't understand. If I read well all savvy
discussions so far,
publishers behind http://schema.org URIs are unlikely to ever
provide any
RDF description, so why are those URIs declared as identifiers of
RDFS
classes in the http://schema.rdfs.org/all.rdf. For all I can see,
http://schema.org/Person is the URI of an information resource,
not of a
class.
So I would rather have expected mirroring of the schema.org URIs by
schema.rdfs.org URIs, the later fully dereferencable proper RDFS
classes
expliciting the semantics of the former, while keeping the
reference to the
source in some dcterms:source element.
Example, instead of ...
<rdf:Description rdf:about="http://schema.org/Person";>
<rdf:type rdf:resource="http://www.w3.org/2000/01/rdf-
schema#Class"/>
<rdfs:label xml:lang="en">Person</rdfs:label>
<rdfs:comment xml:lang="en">A person (alive, dead, undead, or
fictional).</rdfs:comment>
<rdfs:subClassOf rdf:resource="http://schema.org/Thing"/>
<rdfs:isDefinedBy rdf:resource="http://schema.org/Person"/>
</rdf:Description>
where I see a clear abuse of rdfs:isDefinedBy, since if you
dereference
the said URI, you don't find any explicit RDF definition ...
I would rather have the following
<rdf:Description rdf:about="http://schema.rdfs.org/Person";>
<rdf:type rdf:resource="http://www.w3.org/2000/01/rdf-
schema#Class"/>
<rdfs:label xml:lang="en">Person</rdfs:label>
<rdfs:comment xml:lang="en">A person (alive, dead, undead, or
fictional).</rdfs:comment>
<rdfs:subClassOf rdf:resource="http://schema.rdfs.org/Thing"/>
<dcterms:source rdf:resource="http://schema.org/Person"/>
</rdf:Description>
To the latter declaration, one could safely add statements like
schema.rdfs:Person rdfs:subClassOf foaf:Person
etc
Or do I miss the point?
