The record

Purpose: LinkedDataHub is an open-source, low-code platform for managing data, creating visualizations, and building apps on RDF knowledge graphs.
RDF content platform: It can also be used as an RDF-native content management platform.
Features: It provides a UI component library, SPARQL-based creation and editing templates, and SPIN and SHACL constraints for validating incoming data.
Data imports: It supports CSV imports mapped to RDF with SPARQL CONSTRUCT and RDF imports transformed with SPARQL CONSTRUCT.
Authentication: Authentication supports WebID and OpenID Connect with Google and ORCID.
Access control: Access control uses WAC authorizations with read, write, append, and control modes.
Versioning: Git-backed document versioning uses the Memento protocol to access document history.
API: The platform provides a SPARQL endpoint and a read-write Linked Data API, and documents can be served as HTML or RDF from the same URIs.
Integrations: LinkedDataHub uses Apache Jena Fuseki by default and can work with SPARQL 1.1-compatible triplestores that support SPARQL Query, SPARQL Update, and Graph Store Protocol.
Security detail: SPARQL service credentials can use HTTP Basic or Bearer token authentication and are stored in a gitignored secrets folder.
Supported imports: The get-started guide says the currently supported data imports are CSV and RDF.
Support: The documentation lists a mailing list, issue reporting, and support contact as support channels.
Intended users: The product page presents use cases for researchers and data scientists, developers and data publishers, and AI agents and their builders.
