That's a fair point, but we're not trying to duplicate what can be done with Open Badges or what the Verifiable Claims WG <https://www.w3.org/2017/vc/WG/> / Credentials Community Group <https://www.w3.org/community/credentials/> will produce (in fact, we are trying not to duplicate that). For non-verified assertions, a simple hasEOCredential (or whatever) property of Person pointing to an EducationalOccupationalCredential may suffice. When the output of the VCWG / CCG is know that could be converted to schema.org and added to the range of hasEOCredential FWIW, to my mind all statements in schema.org are unverified assertions. Me saying I have a PhD from Bristol University is just as open to challenge as me saying my name Phil Barker. So I think the scope of verifying claims goes way beyond Educational and Occupational Credentials. (A mediating type of similar nature Role <http://schema.org/Role> that can be used with any property might work, it think the wikidata data model works like that.) > What is also unclear to me is how an institution who did previously > offer a creational and has since ceased can continue to advertise that > they have previously offered the credential but are now not doing > business with that token.
