RDF HDT (Header, Dictionary, Triples) is a compact data structure and binary serialization format for RDF that keeps big datasets compressed to save space while maintaining search and browse operations. This makes it an ideal format for storing and sharing RDF datasets on the Web.
This is achieved by organizing and representing the RDF graph in terms of three main components: Header, Dictionary and Triples structure. The Header includes extensible metadata required to describe the RDF data set and its organization. The Dictionary gathers all the terms present in the RDF graph in a manner that permits rapid search and high levels of compression. The Triples component represents the structure of relationships of the RDF graph in a compressed form.
Some facts about HDT:
The size of the files is smaller than other RDF serialization formats. This means less bandwidth costs for the provider, but also less waiti
