Background
The current MP schema has the wikidata_id property set as an integer type which does not pass validation since most wikidata IDs are prefixed with a Q (see T327083#8635819 and https://www.wikidata.org/wiki/Wikidata:Identifiers)
Description
Add a new property to the schema called wikidata_qid which has a type of string to capture the full wikidata id.
Acceptance criteria
- MP monoschema has a new property wikidata_qid added
- Update documentation to include this property
