Header Dictionary Triples

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[cit1]. HDT is an open format in progress of standardization[cit2].

HDT tools

  • hdt-cpp is a library and command-line tool to create and search HDT files[cit3]

  • hdt-java allows integration of HDT with Apache Jena and Fuseki[cit4]

  • HDT-it! is a GUI application for browsing HDT files, which includes a 3D Visualization of the RDF adjacency matrix of the RDF Graph[cit:5]
