Hello 👋
is it possible to add DefinedTerm as an expected type to http://schema.org/learningResourceType?

Background is this:
My project is working as a metadata-hub for educational resources in Germany. We gather material from many different sources and some of them use different vocabularies for defining their learning resource types. We connect the different content sources in our hub, so they can interchange their material.

Problem is:
They will only accept material with metadata they can understand. Thus we are thinking of drawing relations between the vocabs in the background and give each player what they understand. Therefore we are handling learningResourceType entries as a http://schema.org/DefinedTerm. I guess that this could be a use case for other people as well, at least it is quite common to have controlled vocabularies for this property.

An exemplary entry would look like this:

"learningResourceType": {
    "type": "DefinedTerm",
    "name": "Experiment",
    "url": "http://w3id.org/openeduhub/vocabs/learningResourceType/experiment",
    "inDefinedTermSet": "http://w3id.org/openeduhub/vocabs/learningResourceType/"
    },

Thank you and looking forward to discussion!
