Our review
Pros
  • Supports RDF triples and quads with SPARQL, Prolog, RDFS++, and OWL reasoning
  • Combines federation, sharding, replication, geospatial, temporal, and vector capabilities
  • Offers triple-level security plus integrations across analytics and data platforms
  • Supports SPARQL 1.2, RDF 1.2 terms, reasoning, and SHACL validation
  • Combines in-memory, native, federated, and remote repository workflows
  • Includes RDF4J Server and Workbench alongside Java APIs and RDF tooling
Cons
  • Paid licensing is quotation-based rather than publicly listed
  • SQL support is not available
  • Its broad feature set is more specialized than a focused graph database
  • Primarily targets Java developers, narrowing fit for non-Java teams
  • Self-hosted deployment places infrastructure operations on the adopting team
  • Its framework-and-toolkit model is less direct than a hosted database service
