In their own words
GraphDB
GraphDB is a semantic graph database that uses RDF and SPARQL to connect business data and support real-time AI insights. It applies reasoning and semantic search to connected information. Free and Enterprise editions support RDF 1.1, SPARQL 1.1, RDF-Star, SPARQL-Star, and reasoning for RDFS, OWL 2 RL and OWL 2 QL. Listed AI capabilities include GraphRAG, MCP support, no-code RAG chat in Workbench, precision entity linking and natural-language graph queries from LangChain. Integrations include MongoDB, Kafka, JDBC, GraphQL, SQL-accessible data virtualization, and connectors for Lucene, Elasticsearch and Solr. GraphDB Free has a single-core license. Starting with version 11.0.0, every edition requires a valid license, which can be requested for free. Enterprise supports twelve or more cores and features such as parallel query processing, cluster failover, synchronization and load balancing. Enterprise is available on-premise or as a 12-core cluster SaaS through AWS Marketplace and Microsoft Azure Marketplace. GraphDB supports Linux, macOS, Windows, web and self-hosted deployments, with API access.
LinkedDataHub
LinkedDataHub is an open-source, low-code platform for managing data, creating visualizations, and building applications on RDF knowledge graphs. It can also operate as an RDF-native content management platform. The interface includes UI components, SPARQL templates for creating and editing content, and SPIN and SHACL constraints for validating incoming data. CSV and RDF imports are supported, with SPARQL CONSTRUCT used for mapping or transformation. Authentication supports WebID and OpenID Connect with Google and ORCID. WAC permissions cover read, write, append, and control access. Git-backed document history is available through Memento. The platform exposes a SPARQL endpoint and read-write Linked Data API, serving documents as HTML or RDF from the same URIs. It uses Apache Jena Fuseki by default, supports compatible SPARQL 1.1 triplestores, and runs locally with Docker Compose. The project is self-hosted under Apache 2.0.
