Extracting & Display of Genealogy Relationships[edit]

Information about genealogy relationships being stored in Wikidata can be extracted and displayed in various ways:

  1. using RDF query language SPARQL commands
  2. using templates within Wikipedia articles and tools via a webbrowser using readymade queries

Examples of SPARQL Queries[edit]

  (?propertyLabel AS ?edgeLabel)
  wd:Q179577 (wdt:P22|wdt:P25)* ?item.

  {?item p:P22 [ps:P22 ?linkTo; ?ps []].}
  {?item p:P25 [ps:P25 ?linkTo; ?ps []].}

  ?property wikibase:statementProperty ?ps.

  SERVICE wikibase:label {
    bd:serviceParam wikibase:language "en".
    ?item rdfs:label ?itemLabel.
    ?linkTo rdfs:label ?linkToLabel.
    ?property rdfs:label ?propertyLabel.

Seeks to improve both the content of WeRelate AND Wikidata. About 9,000 new Wikidata genealogy claims have been created since May 2017 - on the basis of the WeRelate tree. The python script which performs the WeRelate/Wikidata comparison is available from github.
