Comunica
Comunica is an open-source framework for querying knowledge graphs with SPARQL and GraphQL over decentralized RDF on the Web. It can treat multiple sources as one virtual dataset and identify a source type from its URL. Built-in source types include RDF files, SPARQL endpoints, Triple Pattern Fragments, JavaScript RDF sources, serialized datasets, and HDT files. The framework parses Turtle, JSON-LD, RDF/XML, N-Triples, TriG, and N-Quads, and can serialize results as SPARQL JSON, XML, CSV, TSV, or RDF formats. It supports several SPARQL 1.2 specifications, while SPARQL 1.2 entailment regimes and the Graph Store HTTP Protocol are listed as unsupported. The browser client provides SPARQL and GraphQL-LD queries, Solid authentication, selectable sources, and geospatial results. Developers can combine modules into custom engines or add components, and use Comunica in browsers, JavaScript applications, or from the command line. The default SPARQL engine does not query local files; a separate file engine is intended for that purpose. The project is MIT-licensed for open and commercial use.
