New page

SPARQL is the query language used by the [http://query.personaldata.io query service].

You can read more about SPARQL [https://www.wikidata.org/wiki/Wikidata:SPARQL_query_service/Wikidata_Query_Help here], on Wikidata.
This has different parts:
* [https://www.wikidata.org/wiki/Wikidata:SPARQL_tutorial tutorial]
* [https://www.wikidata.org/wiki/Wikidata:SPARQL_query_service/Building_a_query Building a Query] examples
* [https://www.wikidata.org/wiki/Wikidata:SPARQL_query_service/queries/examples very very very many examples on Wikidata] -- this is the best way to learn, at least for me
* [https://www.mediawiki.org/wiki/Wikidata_Query_Service/User_Manual Wikidata Query Service user manual], which includes an explication of the 'label' service
* a description of the different [https://www.wikidata.org/wiki/Wikidata:SPARQL_query_service/Wikidata_Query_Help/Result_Views views on results] that are possible; note that each view expects the data to arrive for each row in a specific order as a tuple, even bound to a variable of fixed name
* [https://www.wikidata.org/wiki/Wikidata:SPARQL_query_service/A_gentle_introduction_to_the_Wikidata_Query_Service a gentle introduction to the Wikidata Query Service]
