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)

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.
