Very interesting as Wikidata starts beeing part of more external data “flows” I would also like to see that we easy can tell * this is the schema we use inside Wikidata * this is external related schemas other organisations has created for this type of data * how this WD schema relate to an external schema. What parts we map etc.
In Sweden the goverment speaks about basic data (swe. Grunddata) that they will define that I hope the data in Wikidata can “plug-in” and add value to.

There is already a ticket about adding a new data type allowing to link EntitySchemas from statements: https://phabricator.wikimedia.org/T214884 If we don't encounter any major technical issue, this could be done in the incoming weeks.

I've proposed a property, https://www.wikidata.org/wiki/Wikidata:Property_proposal/Shape_Expression_for_class To make this work, is it possible to have a Shape Expression as the value of a statement on Wikidata (and the RDF dump, and WDQS) ? Is there a timescale in which this should become possible ? Thanks, James.
