ISSUE-87: why is sosa-core:observable property renamed

Hi Kerry –

I agree with your overall analysis. Observable-properties are just a kind of quality.

The issue in the context of SOSA here is whether SOSA mentions the superclasses (dul:Quality, GF_PropertyType etc) or do we just include narrower classes here, and assert the fact that they are subclasses of something else in an alignment graph.
There is a related consideration for FeatureOfInterest vs just Feature or even just rdf:Resource.
I had the impression that we were consciously using the more narrowly defined classes in SOSA, but recognize that there will be alignment to the more general cases outside the core.

Concerning the name: the issue here is that not all properties are amenable to estimation through sensing, etc.
Some feature properties (like ‘name’ or ‘owner’) are typically asserted or recorded in some register, and you don’t obtain these by a process of observation.
