We are doing a SHACL expression of the European DCAT-AP. The draft is at https://github.com/SEMICeu/dcat-ap_shacl/tree/master/shacl (in three parts: mandatory classes, controlled vocabularies and properties).

Comments welcome!

I was hoping that there could be a human-simple syntax that could be translated to SHACL or ShEx or any other schema (e.g. Schematron).
However, that might result in a very complex syntax in the profile, and another aspect of DCAP is that it documents (for humans) decisions and practices relating to the metadata.
