add lang to definitions, remove lang from labels

[VladimirAlexiev]

CIM terms are defined like this:

cim:AsynchronousMachineUserDefined a owl:Class ;
  rdfs:label "AsynchronousMachineUserDefined"@en ;
  rdfs:comment "Asynchronous machine whose dynamic behaviour is described by a user-defined model." ;

The label has lang tag, the comment doesn't.
I think it should be the other way around:

• label equals the local name of the term's URL, and that won't be translated. If it was written as a phrase "Asynchronous Machine User Defined", I agree with the lang tag. But as written, I'd say it should not have a lang tag
• comment is an English sentence, so should have a lang tag

Yes, this is a mistake. In ED2 we used skos:definition rather than rdfs:comment I like the idea of clearly state that something is a definition rather than just a comment. What do you think?

[VladimirAlexiev]

Ontologies have traditionally used rdfs:comment for definitions.
Taxonomies use skos:definition and not just for Concepts, but some also use it for ConceptScheme.
I think you should keep rdfs:comment; and can use extra SKOS props (eg skos:scopeNote) for additional aspects.
