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; foaf:primaryTopic<http://www.productontology.org/id/Hammer>. <http://www.productontology.org/doc/Hammer> a foaf:Document; foaf:primaryTopic<http://www.productontology.org/id/Hammer>. <http://www.productontology.org/id/Hammer> a owl:Class; 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/goodrelations/v1 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. ;-) Martin -------------------------------------------------------- martin hepp e-business& web science research group universitaet der bundeswehr muenchen e-mail: [email protected] phone: +49-(0)89-6004-4217 fax: +49-(0)89-6004-4620 www: http://www.unibw.de/ebusiness/ (group) http://www.heppnetz.de/ (personal) skype: mfhepp twitter: mfhepp Check out GoodRelations for E-Commerce on the Web of Linked Data! ================================================================= * Project Main Page: http://purl.org/goodrelations/
