“Binary RDF Representation for Publication and Exchange (HDT)” published as a W3C Member Submission

Posted on May 3, 2011 by Ivan Herman

The “Binary RDF Representation for Publication and Exchange (HDT)” specification has been published as a W3C Member Submission, co-authored by experts from DERI Galway, Free University of Bozen-Bolzano, the Open University, Universidad Politécnica de Madrid, Alcatel-Lucent, Cisco, OpenLink Software, and Profium Ltd. HDT is an RDF data-centric format which reduces verbosity in favor of machine-understandability and data management. HDT introduces a new representation format using the skewed structure of big RDF graphs to achieve large spatial savings. The Submission also defines extensions to the VoID vocabulary to provide metadata related for HDT formats, graph statistics and a general category of publication items.
