@Tacsipacsi Labels are missing at https://www.wikidata.org/wiki/Wikidata:Database_reports/Constraint_violations/P2088. Maybe because it has a much bigger number of violations?

Here's the goal: a SPARQL query should return all violations of a certain kind, with a possible data lag of a few hours.
So you need:

  • a baseline of having processed all items (TODO)
  • processing of changed items (DONE)
  • periodic processing of every item because constraint definitions or implementations can change globally (TODO?)

@Mohammed_Sadat_WMDE Can you explain why a QS batch that merely deletes (does not create statements with qualifiers) returns errors and has to be restarted 10 or 20 times until all deletes go through? Or is "throttling" the same as "failing"?

@Addshore I think that's a fair description. To add:

  • those pages are linked to the Discussion pages of each property, so are perceived as an integral part of WD, eg:
    • Database reports/Constraint violations/P245: KrBot
    • Database reports/Complex constraint violations/P245: not sure who generates
    • Database reports/Humans with missing claims/P245
    • And there's a link for each individual constraint
  • It also generates useful Type Statistics (eg https://www.wikidata.org/wiki/Wikidata:Database_reports/Constraint_violations/P245#Types_statistics) that allow us to evaluate whether the type constraints are right. Eg the first "No" is https://www.wikidata.org/wiki/Q15632617 "fictional human" (ULAN is only supposed to include real persons and organizations) and I can search for Q15632617 to see whether to remove that type from WD items, or to add it to the ULAN property

Getty ULAN has a whole slew of "unknowns" http://vocab.getty.edu/doc/#ULAN_Hierarchy_and_Classes (note: the counts are several years old, I imagine there are a few more thousands of those now):

  • 500355043 Unidentified Named People includes things like "the master of painting X"
  • 500125081 Unknown People by Culture includes things like "unknown Egyptian" (to be used in situations like "unknown creator, but Egyptian culture"). We've modeled those as gvp:UnknownPersonConcept and groups (schema:Organization) but users still think of them as "persons".
  • Further, there are things like "unknown but from the circle of Rembrandt" or "unknown but copy after Rembrandt" etc, about 20 varieties of them, see

Agree with @PKM: the name is "Gades"@phn-Latn, "Cadiz"@es and I guess "Cadiz"@en.
@Lydia_Pintscher will you name the language "Phoenician (Transliterated)"? The Getty does that, search for Chinese in that page and you'll see eg

		............................ Chinese (transliterated Hanyu Pinyin) (language)
		............................ Chinese (transliterated Pinyin) (language)
		............................ Chinese (transliterated Pinyin without tones) (language)
		............................ Chinese (transliterated Tongyong Pinyin) (language)
		............................ Chinese (transliterated Wade-Giles) (language)

This returns False, which I believe is a bug in Blazegraph

select * {
  bind (
    sameTerm(<https://en.wikipedia.org/wiki/University_of_Tromsø>,
     <https://en.wikipedia.org/wiki/University_of_Troms%C3%B8>)

Can you point to the encoding rules so we do the same before querying. Sparql's encode-for-uri encodes everything except upper- and lower-case letters A-Z, the digits 0-9, HYPHEN-MINUS ("-"), LOW LINE ("_"), FULL STOP ".", and TILDE "~". See https://www.w3.org/TR/xpath-functions/#func-encode-for-uri.

Ok, this works and returns 18650 rows as expected:

prefix wd:   <http://www.wikidata.org/entity/>
prefix wdt:  <http://www.wikidata.org/prop/direct/>

So can you perhaps rewrite the query in a way that it works?

I want to use federation from an external repo (as the descr says "another repo").
You can test the bug either using an external repo, or self-federation.

VladimirAlexiev added a comment to T155425: Add monolingual language code phn (Phoenician).

phn means "Phoenician in Phoenician script" but the example given is in Latin script, thus it is phn-Latn.

VladimirAlexiev added a comment to T155425: Add monolingual language code phn (Phoenician).

https://www.wikidata.org/wiki/Wikidata:Project_chat#Phoenician_language: according to the IANA lang tag list, the default script for this language is "Phnx" Phoenician but the example there is given in Latin transcription so shoul de denoted like "gadir"@phn-Latn.

  • To capture this, I believe you should register a lang tag phn-Latn with name eg "Phoenician (Latin transcription)".
  • The tag phn should be used only if you install Phoenician script (alphabet) in the language tools; and somehow direct the user to select "Phoenician (Latin transcription)" if they intend to enter a transliterated label
