Interesting idea. However, I wanted to avoid owl:inverseOf etc to avoid OWL entirely (in order to meet the “Owl is ridiculous” and “gosh , I need to learn about owl”  crowds.)

I thought it made sense to keep to rdf alone.
 I understood the sentiment favoured instead some kind of “simple” OWL.

I, for one, never really understood  what “simple” means for sosa, but I suppose for some people it means just exactly what is in sosa now. And  just now we agreed that owl:AnnotationProperty  can appear in sosa, but I guess that that is “simpler” than owl:inverseOf.

Anyway – I think, from the arguments at the time, the schema.org solution you propose would be interpreted  as the same as “documentation” (B),   and therefore has been decided already, although I don’t recall your (C) as coming up  at the time.

So +0 from me.

Btw – the earlier question about “meta:” – mea culpa – but I stand corrected.  Great to have fresh eyes on this.

Dear all,

I don't want to mess around with the decisions that may have been taken already, and that I may not be aware of.
but this issue-72 is still open so I thought it could be worth adding my two cents there :

If we are so much keen in using pseudo, non Linked-data-conforming properties from schema.org<http://schema.org> , maybe it's important to let you know the following:

There is a third possibility for inverseOf:

(A)    The pair is to be related by an owl:InverseOf declaration; or
(B)    ruled-out:  The pair are not to be axiomatically  related but documentation is to be used to make the  inverse intention clear
(C)   The pair is to be related by a schema:inverseOf pseudo axiom.

To me, using that pseudo property could help remove OWL axioms completely from the term definitions.

A camp was at 8 and B camp was at 1.
How many would like to change from camp A to camp C ?

Kind regards,

This would bring the A camp to 8 and the B camp to 1 vote.
