Mirror ssn resources in sosa namespace #92

Closed dr-shorthair closed 1 year ago

dr-shorthair commented 1 year ago

All the ssn: classes and properties are mirrored into the sosa: namespace but remain in the SSN graph. The existing ssn: resources have owl:equivalentClass or owl:equivalentProperty axioms to the new resources.

Fixes #48

Refactor to remove commit removing inverseOf

The need for this inverseOf property depends somewhat on the final resolution of the madeBySensor vs madeByObserver issue. Are they equivalentPropertys?

I will re-instate it for now, so we can move forward.

dr-shorthair commented 1 year ago

Hmm. If both madeBySensor and madeByObserver are inverseOf the same property, then I think this entails they are equivalentProperty.

dr-shorthair commented 1 year ago

Should sosa declare equivalence - or only ssn?

Unclear which resource should have the owl:equivalentX axiom attached. The original ssn: resource? The new sosa: resource? Both?

For the time being they sit on the sosa: resource so the original resources are untouched internally.
