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)

After a second thought, I have refrained from setting the constraint status (P2316) to mandatory constraint (Q21502408): During, e.g., larger Mix-n-match runs multiple temporary violations of the constraint may be unavoidable. Jneubert (talk) 15:09, 27 April 2018 (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
Report load query and execute
Full mapping, with relation types (sort by relation type to spot missing ones) wikidata_mapping
Single value violations (multiple exact matches from an item) exact_single_violations
Distinct values violations (multiple exact matches to different items) exact_distinct_violations
Multiple ID values per item (which may or may not indicate an error) multiple_id_values
Same ID value in different items (which may or may not indicate an error) same_id_value
All non-exact relationships, with a link to search Wikidata for possible newly introduced better matches inexact_wikidata_mapping

Note: Currently, only STW sub-thesaurus G (geographic names) is mapped to Wikidata. Jneubert (talk) 15:23, 6 November 2017 (UTC)

Mapping of STW sub-thesaurus W (Economic sectors) is now on the way. Jneubert (talk) 07:08, 29 August 2018 (UTC)
