Non-sensible value for sm:contentLanguage in most FIBO ontologies

[rivettp]

Pretty much all FIBO ontologies declare a sm:contentLanguage of http://www.w3.org/standards/techs/owl#w3c_all
However that now redirects to https://www.w3.org/TR/?tag=data#w3c_all which gives a page listing all 150 or so data-related W3 specifications which I'm sure was not the intent.
The specification for the property sm:contentLanguage says "a link to the core language and/or specification of the model/electronic file, for example, UML, OWL, SysML, BPMN, including linking to the version of the language in question"
In which case surely the URL should be http://www.w3.org/2002/07/owl#

There's also https://www.w3.org/ns/formats/, does it make any sense to mark different release formats with some of these? Perhaps no because it's in the filename.

@VladimirAlexiev those represent specific serializations, and the idea here is to represent OWL in general. @ElisaKendall has started to use a link to the OWL Quick Reference https://www.w3.org/TR/owl2-quick-reference/ but I still prefer the OWL namespace URI. Any thoughts?

[VladimirAlexiev]

Agree, the namespace is better. And if possible, use a real URL, not a literal with datatype AnyURI
