HornDB docs

Guides for learning HornDB and reference for looking up exact behaviour.

HornDB is a graph database with a built-in OWL 2 RL reasoner: load RDF, run SPARQL, and get answers that include what the reasoner inferred — with provenance back to the facts that produced them. These docs cover two kinds of page, so you always know what you’re reading.

Where to go

• Guides — tutorials that walk you through a task end-to-end, how-to guides for a specific goal, and explanations of the design behind HornDB. Start with Get your first reasoned answer in five minutes if you are new here.
• Reference — exact syntax and behaviour: SPARQL functions and operators, configuration keys, and error codes. Look here when you already know what you want and need the precise details.
