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]

SELECT
  ?item

Examples of Tools

[edit]
  • EntiTree navigable Family Tree (D3 inspired) using ReactJS
  • GeneaWiki is a simple external graph viewer showing genealogy information in WikiData.
  • Ancestor viewer a viewer tool that shows also birth dates and images of the persons (if available), limited to the display of up to four generations, just parent/kip display, no display of siblings
  • Relator a viewer tool that shows also siblings and spouses, limited to the display of up to three generations
  • Gravemap tool displaying graves with coordinates in Wikidata and if a grave has a picture se graves.wiki
  • Wikimedia Alignment Project - an active project on WeRelate. Over 31,500 WeRelate Person pages are tagged with their corresponding Wikidata ID. 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.
