Looking for items where category saved in sitelink to Commons does not match P373

I observed that often after category rename, new category is placed in a sitelink but P373 is not updated. So I am looking for such cases. --Jarekt (talk) 14:15, 25 October 2017 (UTC)

schema:name returns two parts: value and language. You need to add str() to remove the language info and to get a pure literal value. Only those values you can compare with wdt:P373 which is from the beginning a pure literal value.

SELECT ?item ?commonsCategory ?commonsSitelink ?category WHERE {
  ?item wdt:P373 ?commonsCategory . 
  ?commonsSitelink schema:about ?item; schema:isPartOf <https://commons.wikimedia.org/>; schema:name ?sitelink_label .
  FILTER(STRSTARTS(STR(?commonsSitelink), "https://commons.wikimedia.org/wiki/Category")) . # sitelink to a category

Query to keep Commons Creator page (P1472) property and Commons creator templates in synch

Wikidata Commons Creator page (P1472) property and Commons creator templates have kind of reciprocal relationship: Commons Creator page (P1472) point from an item to one of Commons Creator templates and each creator template has "Wikidata" field with a q-code of the item. If creator template has "Wikidata" field with a q-code of some item but that item does not have matching Commons Creator page (P1472) property than the creator template is placed in c:Category:Creator templates with Wikidata link: item missing linkback. However if some item has I can not figure out how to write a query or generate a list of q-codes for items with Commons Creator page (P1472) property that point to a templates that do not have "wikidata" field pointing back. Any idea if such a query can be written or if some tool like petscan, etc. could help me? --Jarekt (talk) 02:39, 16 June 2017 (UTC)

If I understand correctly what you're looking for, the new MWAPI for WDQS can be of some help.

However it may not return all wanted entries, due to limitations with MWAPI call results limit. This limit really doesn't make sense in the SPARQL context in my opinion, especially for generators. @Smalyshev (WMF): any chance the engine can iterate by using continue parameter? -- Nono314 (talk) 19:39, 16 June 2017 (UTC)

Theoretically, it is possible, practically, different APIs seem to do continuations differently, so it may be hard to implement it in generic way. E.g. for this API, continue is in gcmcontinue, but for search it's sroffset, and for querypage it's qpoffset. If I figure out a way how to generalize it, I can implement it.

Though one needs to be careful as result may be too big and lead to timeouts. --Smalyshev (WMF) (talk) 22:54, 16 June 2017 (UTC)

Sure, as for any SPARQL query! @Smalyshev (WMF): Thanks for having a look at it. I think it really makes sense for generators. So we could pass the right parameter in the query, and you would just iterate until you get batchcomplete in result? And maybe a way to specify a maximum number of iterations? -- Nono314 (talk) 23:38, 16 June 2017 (UTC)
