Distinct values: this property likely contains a value that is different from all other items. (Help)Exceptions are possible as rare values may exist.
List of this constraint violations: Database reports/Constraint violations/P3911#Unique value, SPARQL (every item), SPARQL (by value), SPARQL (new)
Single value: this property generally contains a single value. (Help)Exceptions are possible as rare values may exist.

Required qualifier “mapping relation type (P4390)”: this property should be used with the listed qualifier. (Help)Exceptions are possible as rare values may exist.

Allowed entity types are Wikibase item (Q29934200): the property may only be used on a certain entity type (Help)Exceptions are possible as rare values may exist.

Mapping relation mandatoryEdit
I've added a mandatory constraint for mapping relation type (P4390). All 395 existing values of the property were set to exact match (Q39893449), with a few changed manually afterwards. Jneubert (talk) 15:54, 19 October 2017 (UTC)
Reports for the maintenance of the STW ID / Wikidata mappingEdit
The rationale behind these reports is two-fold:
- creating a replacement for the standard "single"/"different" constraint violation reports, which does not work well with n:m mappings (whereas the warnings of the "check constraints" gadget are helpful against accidentally introduced redundancies)
- helping to trace the mapping, particularly in regard to the non-exact mappings, and supporting search for possible better matching newly introduced Wikidata items
