Query results: Results can be serialized in SPARQL JSON, XML, CSV, TSV, and several RDF formats.comunica.dev · 29 Sept 2026
Platforms: Documentation describes use in browsers, Node.js applications, the command line, Docker containers, and as a SPARQL protocol endpoint.comunica.dev · 29 Sept 2026
Browser client: The live Web client offers SPARQL and GraphQL-LD queries, Solid authentication, selectable data sources, and geospatial results.query.comunica.dev · 29 Sept 2026
Customization: Users can configure their own query engine by combining modules and can extend it with new components.comunica.dev · 29 Sept 2026
Open source: Comunica is available under the MIT license for use in open and commercial projects.comunica.dev · 29 Sept 2026
Security and compliance: The pages reviewed describe supported standards and features but do not state a security certification or compliance program.comunica.dev · 29 Sept 2026
Support: The project directs questions to its Gitter community and GitHub discussions, bugs to its GitHub issue tracker, and commercial support inquiries to an email contact.comunica.dev · 29 Sept 2026
Limits: The specifications page lists SPARQL 1.2 Entailment Regimes and Graph Store HTTP Protocol as not yet supported.comunica.dev · 29 Sept 2026

Purpose: Comunica is a knowledge graph querying framework for flexible SPARQL and GraphQL queries over decentralized RDF on the Web.comunica.dev · 30 Sept 2026
Federated queries: It can query multiple different sources together as one virtual dataset.comunica.dev · 30 Sept 2026
Source types: Built-in source types include RDF files, SPARQL endpoints, Triple Pattern Fragments, JavaScript RDF sources, serialized datasets, and HDT files.comunica.dev · 30 Sept 2026
RDF formats: Supported RDF input formats include Turtle, TriG, JSON-LD, RDFa, RDF/XML, N-Triples, N-Quads, Notation3, and Microdata.comunica.dev · 30 Sept 2026
Query standards: The project lists SPARQL 1.2 query, update, federated query, service description, result formats, and protocol among supported specifications.comunica.dev · 30 Sept 2026
Known limits: SPARQL 1.2 entailment regimes and the Graph Store HTTP Protocol are listed as unsupported.comunica.dev · 30 Sept 2026
Runtime options: Comunica can be used in browsers, JavaScript applications, and from the command line.comunica.dev · 30 Sept 2026
Local files: The default Comunica SPARQL engine does not allow querying local files for security reasons; the separate Comunica SPARQL File engine is intended for that use.comunica.dev · 30 Sept 2026
Solid support: Comunica supports querying public and authenticated Solid pod documents, and offers experimental link traversal across pods.comunica.dev · 30 Sept 2026
AI integration: Comunica engines can be exposed through MCP so AI agents can query decentralized RDF knowledge graphs.comunica.dev · 30 Sept 2026
Customization: Users can configure their own query engine by combining modules or extend Comunica with new components.comunica.dev · 30 Sept 2026
