Re: What would break? Re: httpRange-14

Hi all:

> My example about rdfs:isDefinedBy remains, a majority of ontologies constructed by folks who grok the fundamentals still don't include rdfs:isDefinedBy relations. Thus, I've resorted to fixing those ontologies when ingested instead of pinging the ontology authors. The same thing applies (even more) to wdrs:describedby which ended getting fixed in response to my "tale of two missing predicates" post [1] around the time of the Toucan post etc..

FYI:

http://www.productontology.org implements both rdfs:isDefinedBy and wdrs:describedby, I hope correctly.

See

http://www.productontology.org/doc/Hammer (with conneg)
http://www.productontology.org/doc/Hammer.ttl
http://www.productontology.org/doc/Hammer.rdf



In fact, www.productontology.org tries to model all distinct conceptual entities and their relationships in a very granular way, see:


<http://www.productontology.org/doc/Hammer.rdf> a foaf:Document;
	foaf:primaryTopic <http://www.productontology.org/id/Hammer>.
<http://www.productontology.org/doc/Hammer.ttl> a foaf:Document;

	rdfs:isDefinedBy <http://www.productontology.org/#>;
...
	wdrs:describedby <http://www.productontology.org/doc/Hammer.rdf>, <http://www.productontology.org/doc/Hammer.ttl>;
	foaf:homepage <http://www.productontology.org/doc/Hammer.html>;
	foaf:page <http://en.wikipedia.org/wiki/Hammer>.

GoodRelations, the Vehicle Sales Ontology, the Tickets Ontology, the Volkswagen Car Options Ontology, and the Volkswagen Vehicles Ontology all contain at least rdfs:isDefinedBy axioms.

http://purl.org/vso/ns
http://purl.org/tio/ns
http://purl.org/coo/ns
http://purl.org/vvo/ns

But I think you can hardly get this correct without

1. reading RFC 2616 over and over again and
2. having the privilege of getting feedback from Kingsley.
