These SPARQL queries can be used in the local Query Service. See Wikidata's tutorial for an overview. The custom prefix declarations are required, and do not autocomplete (wd: and wdt:does, but actually queries Wikidata).

Start

All editions with publication date ordered by date

PREFIX rlwd: <https://riga-literata.wikibase.cloud/entity/>
PREFIX rlwdt: <https://riga-literata.wikibase.cloud/prop/direct/>

SELECT ?edition ?editionLabel ?date

  ?edition rlwdt:P1 rlwd:Q3033;
           rlwdt:P49 ?date.
  
SERVICE wikibase:label { bd:serviceParam wikibase:language "en,la,lv". }
