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.
