Hi, Ref: <http://esw.w3.org/topic/SemanticWebTools> The SemWeb folks have a collection of some of the tools in a wiki. I've been playing around with some of the OWL checkers [1] and found at least one bug in the schema: <rdfs:Class rdf:about="http://www.w3.org/ns/earl#SingleAssertor"> <rdfs:label xml:lang="en">Single Assertor</rdfs:label> <rdfs:comment xml:lang="en">One person or evaluation tool that claims assertions</rdfs:comment> <owl:oneOf rdf:parseType="Collection"> <owl:Thing rdf:type="http://www.w3.org/ns/earl#Software"/> <owl:Thing rdf:type="http://xmlns.com/foaf/0.1/Agent"/> </owl:oneOf> </rdfs:Class> Should read: <rdfs:Class rdf:about="http://www.w3.org/ns/earl#SingleAssertor"> <rdfs:label xml:lang="en">Single Assertor</rdfs:label> <rdfs:comment xml:lang="en">One person or evaluation tool that claims assertions</rdfs:comment> <owl:oneOf rdf:parseType="Collection"> <owl:Thing rdf:about="http://www.w3.org/ns/earl#Software"/> <owl:Thing rdf:about="http://xmlns.com/foaf/0.1/Agent"/> </owl:oneOf> </rdfs:Class> ...in other words rdf:about instead of rdf:type for the oneOf construct. It also seems that the cardinality restrictions are implicitly creating a parent (anonymous) class because of the <rdfs:subclassOf> construct. Let me know if you have other observations or findings...
