Re: Accreditation

Nicholas,

Not all of those you listed would ideally use the term "accredited".

UNESCO is a registering authority.

Licensing is a different term, but that could easily be swapped out with
the term "accrediting".

But overall, I think your onto something.  To be able to easily say "this
Thing has met or achieved certain criteria."

In Freebase, we developed the metaschema of HasCertification, which you can
see here (and hover over the source/target column to see some of the
predicate paths):

https://dev.freebase.com/base/fbontology/metaschema/relationship_id/certification?links

The basis of which is to capture the idea of a relationship between an
entity and a formal recognition (e.g. of an achievement or of having met
certain criteria) that it has been granted by another entity.

Broadly, the Level should be freeform, I agree, and that could sit under
Intangible.  I think that Level could even be abstracted to just broadly,
Category.  Where my discussion of which Martin commented on and picks up
previously in another thread on this list.
