Duplicate of P3365?

This seems to be a duplicate of Property:P3365. -- Okhjon (talk) 13:10, 9 February 2019 (UTC)

@Okhjon: It's not, it has formatter URL "...$1__(Enciclopedia-Italiana)/", not simply "...$1", and links to Enciclopedia Italiana, not to Enciclopedia Treccani online; it's true that the values often coincide with P3365. --Epìdosis 13:40, 9 February 2019 (UTC)

Thank you! -- Okhjon (talk) 13:45, 9 February 2019 (UTC)

Appendices

Enciclopedia Italiana in some cases has more than one entry for a single subject because the same subject appears in one or more appendices (e.g. Italo Balbo (Q1056) or Benito Mussolini (Q23559)); except one entry, the others cointain the string "_res-"; this string usually (but not always, e.g. Thucydides (Q580356)) indicates that there are many entries about the same subject.

SELECT ?item ?identifier WITH {
  SELECT ?item WHERE {
    ?item p:P4223/ps:P4223 ?identifier .
  } GROUP BY ?item HAVING(COUNT(*) = 1)
} AS %subquery WHERE {
  INCLUDE %subquery .
  ?item p:P4223/ps:P4223 ?identifier .
  FILTER(CONTAINS(?identifier, '_res-')) .
}

Try it!

Here is a list of items having only one entry for Treccani's Enciclopedia Italiana ID (P4223) and this entry cointains the string "_res-" (most of them may require a check in order to discover other entries). --Epìdosis 18:19, 19 April 2019 (UTC)

Use with author strings

SELECT ?item ?itemLabel (URI(CONCAT("http://www.treccani.it/enciclopedia/",?ei,"_(Enciclopedia-Italiana)")) AS ?eiUrl) ?author_string
WHERE {
  ?item p:P4223 ?stat .
  ?stat ps:P4223 ?ei .
  ?stat pq:P2093 ?author_string .
	SERVICE wikibase:label { bd:serviceParam wikibase:language "it,en" }
}

Try it!

In many cases it should be considered the possibility to create items for the authors of the entries. --Epìdosis 12:22, 29 December 2019 (UTC)

Authors who are also subjects of articles and absent on it.wikipedia

#Authors of articles of the Enciclopedia Italiana which are also subjects of articles of Enciclopedia Italiana and are absent on it.wikipedia
SELECT DISTINCT ?aut ?autLabel
