Querying Lingua Libre

Core structures

The data model includes 3 core concepts of Lingua Libre : language, speakers, recordings. Items exist for each of these 3 dimensions. Those items have properties, which themselves have various values. This, all together, creates our database.

Language

See also Help:SPARQL#Languages, LinguaLibre:List of languages

This is the language of a speaker or of a recording. This property may point to a language defined on Wikidata (wikidata:Q34770).

Speaker

See also Help:SPARQL#Speakers, DataViz:Speakers.

The speaker is the person that pronounced one or several words in an audio recording. There are various information on the speaker such as their residence at the time of recording and their native tongue.

Audio recordings

See also Help:SPARQL#Recordings, DataViz:Records.

Every recording created with the Record Wizard is added into the database along with some metadata that includes the date the recording was created, the speaker and the language.
