Integrating Wikidata and other linked data sources – Federated SPARQL queries | The Su Lab

"This blog is about running federated SPARQL queries on Wikidata.  A federated query is a special type of SPARQL query that runs on more then one SPARQL endpoint. It allows access to multiple linked data resources in a single query. Below is a template of a federated query.

The WikiData Query Service (WDQS) now supports federated SPARQL queries on a limited number of endpoints. Remote SPARQL endpoints can be added to the list of supports endpoints by nomination."
