Stardog is an enterprise knowledge graph platform that unifies data across silos using a semantic data layer combining knowledge graphs, virtualization, inference, and AI. The platform enables organizations to query data via SPARQL, GraphQL, and natural language while supporting RDF, OWL reasoning, and virtual graphs over relational sources. Stardog exposes a comprehensive HTTP API for database, query, transaction, and admin operations using HTTP Basic or OAuth Bearer authentication.
