*Header Dictionary Triples*, or *HDT*, is a binary serialization format for RDF
datasets. It is capable of compressing RDF data while maintaining search and
browse operations without prior decompression^<<1>>^. HDT is an open format in
progress of standardization^<<2>>^.

= HDT tools

- `hdt-cpp` is a library and command-line tool to create and search HDT files^<<3>>^
- `hdt-java` allows integration of HDT with Apache Jena and Fuseki^<<4>>^
- `HDT-it!` is a GUI application for browsing HDT files, which includes a 3D
   Visualization of the RDF adjacency matrix of the RDF Graph^<<5>>^
