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 

#defaultView:Graph
SELECT
  ?item
  ?itemLabel
  ?linkTo
  ?linkToLabel
  (?propertyLabel AS ?edgeLabel)
{
  wd:Q179577 (wdt:P22|wdt:P25)* ?item.

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