107 move systemkind to system capabilities #229

Closed dr-shorthair closed 1 day ago

I've taken Alex's proposal and moved the classes, properties and related axioms into the System Capabilities extension module.

I'm fine with this but could we just use the ssn namespace (http://www.w3.org/ns/ssn/) for the capabilities module (instead of the old ssn-system, http://www.w3.org/ns/ssn/systems) now that we moved pretty much everything else to sosa?

And deprecate concepts in ssn-system just like we did for the ssn concepts we moved to sosa?

@alexrobin interesting proposal. However, I'm not sure it works -

We 'emptied out' the ssn: ns - the terms that were in there are now tagged 'deprecated'.
The SSN module now only houses the axiomatization of the SOSA modules - as in the previous version.

The plan is that dereferencing http://www.w3.org/ns/ssn/ should get an ontology that supports everything that the previous edition did (the deprecated terms are still quietly imported), though it will also import additional terms in the sosa: ns.

So I think it would be confusing to make ssn: do double duty, also housing the System Capabilities terms.

Update team agreed not to introduce a specific SystemKind class.
