As a Wikidata Query Service user I want to query statements using the EntitySchema data type in order to see which class of Items, Properties and Lexemes are governed by a particular EntitySchema.

Problem:
This should be possible with the creation of the new data type, but will require validation by the WMF.

We will need to send an Item with a statement linking to an EntitySchema in .ttl format that can then be loaded into the Wikidata Query Service to see if it all is fine.

Before we send this we will need to have the data type on beta: T332725
And the EntitySchema concept URI linked in the RDF output: T336056

An example Item on beta: https://wikidata.beta.wmflabs.org/wiki/Q123

Acceptance criteria:

• .ttl file has been sent to the WMF for confirmation
• WMF have confirmed that the new data type is queryable by the Wikidata Query Service
