About LinkedDataHub

LinkedDataHub (LDH) is open source software for managing data, creating visualizations and building applications on RDF knowledge graphs. It started as a tool for publishing Linked Data and grew into a multi-purpose data-driven platform, aimed at researchers who need an RDF-native FAIR data environment and developers who want a declarative full-stack framework for knowledge graph applications.

Its distinguishing trait is a completely data-driven architecture: applications and documents are defined as data, managed through a single generic HTTP API and presented with declarative technologies such as XSLT, with a default structure and interface that can be fully overridden. Unless custom server-side processing is needed, no imperative code in Java or JavaScript is required. XHTML documents can be edited in place with an RDFa-aware rich text editor that links selected text to knowledge graph terms. Version 6 redraws the interface on a bundled design system and drops Bootstrap 2.

Topics include SPARQL, triple stores, OWL, WebID and OpenID Connect. LinkedDataHub is licensed under Apache-2.0, and a getting started guide and changelog document installation and upgrades.
