SPARQL (intermediate)

Revision as of 11:33, 21 August 2022 by Yug (talk | contribs) (→‎Notable elements)

Help:SPARQL 2 will explore federated queries fetching data from both LinguaguaLibre and Wikidata's endpoints, then Wikidata Lexemes, an emerging source of lexicographic data. The duo can be a solid combo to provide lexicographic and multimedia (audio recordings and images) for either Wikimedia modules or web developers.

SPARQL to persitent data

Some SPARQL queries are meaningful but heavy and overly slow. This administrator tool stores or updates the response data on LinguaLibre, within a wikipage. Stored data can then be loaded in <0.1 second. Multiple data can also be merged via a common property if any.


Federated queries

  • To query Lingualibre from Wikidata, use SERVICE <https://lingualibre.org/sparql>.
  • To query Wikidata from LinguaLibre, use SERVICE <https://query.wikidata.org/sparql>.

Retrieve data of LinguaLibre from Wikidata

To run on WDQS.[1] It lists the existing levels in LinguaLibre.
