Sure does rock. As you know, I never venture into ontology definition, to avoid displaying my ignorance, but now and then... :-) Suggestion: The RDFS will (I think!) perpetuate the classic problem (being a natural translation), in that there are lots of range strings. For example: schema:currenciesAccepted a rdf:Property; rdfs:label "Currencies Accepted"@en; rdfs:comment "The currency accepted (in ISO 4217 currency format)."@en; rdfs:domain schema:LocalBusiness; rdfs:range xsd:string; rdfs:isDefinedBy <http://schema.org/currenciesAccepted>; . and schema:headline a rdf:Property; rdfs:label "Headline"@en; rdfs:comment "Headline of the article"@en; rdfs:domain schema:CreativeWork; rdfs:range xsd:string; rdfs:isDefinedBy <http://schema.org/headline>; . And even productID I count 53 "rdfs:range xsd:string" and 8 "rdfs:range [ owl:unionOf (xsd:decimal xsd:string) ]" of this kind. As I say, I think that means that to conform, I can't have a Resource as Range. So it is institutionalising a Bad Thing, simply because schema.org says that, for example, "productID" is "text". Of course, people who use http://schema.rdfs.org/ probably will use Resources for places, currencies, etc, (as they should) so maybe the RDFS needs to reflect this? Won't try and suggest...
