qEndpoint

What qEndpoint is

qEndpoint is a free, open-source RDF triple store for hosting and querying RDF data. It supports full-text search and GeoSPARQL, and can run as a standalone SPARQL endpoint or as a dependency in another application. Users can write and execute SPARQL queries through its GUI or send queries through a RESTful HTTP API; the project lists SPARQL 1.1 support. Datasets can be uploaded in formats supported by RDF4J, including RDF/XML, Turtle, N-Triples, N-Quads, JSON-LD, TriG, and TriX. Query results can be returned as JSON, XML, or Binary RDF. Docker images are available for qEndpoint and for qEndpoint with a Wikidata index; the latter supports wikidata_truthy and wikidata_all datasets. Memory requirements vary: the Docker README sets 6G by default, advises against less than 4G for large datasets, and gives a minimum of 10G for Wikidata-all. Installation is documented through Scoop and Homebrew, and a CLI ZIP release asset is available. The README describes use with Wikibase and says Kohesio and QAnswer use qEndpoint.
