Key concepts Header–Dictionary–Triples organization; RDF compression; searchable binary data; C++ and Java libraries; Apache Jena and Jena Fuseki integration; the HDT-it GUI.

How you’d use it Keep application RDF data in HDT through the C++ or Java libraries, integrate it with Jena or Fuseki, or use HDT-it on Windows, macOS, or Linux to generate and browse HDT files.
