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>.
To query Commons from Lingualibre, use SERVICE <https://commons-query.wikimedia.org/sparql>.

Retrieve data of LinguaLibre from Wikidata

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