In their own words
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.
