</span></i></b>[2] steht für „Header, Dictionary, Triples“ und ist ein RDF-Dateiformat, das die Daten sowohl komprimiert, als auch Indexierung beinhaltet. So können die Daten effizient verteilt und speicherplatzsparend abgelegt werden und sind gleichzeitig
abfragbar. Beispielanwendungsfälle und Tools werden ebenfalls unter [2] ausgeführt. Ein Beispiel für die Nutzung wäre auch die Einbindung in einen Triple Pattern Fragments Server<span style="color:#993366">

Ende Mai über das weitere Vorgehen entscheiden.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="font-size:10.0pt;font-family:"Verdana","sans-serif"">We made available the latest versions of the RDF data dumps in the file format HDT. For now this is a one-time, experimental offer for the datasets "ZDBTitel",
"DNBTitel" and "GND" [1].<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="font-size:10.0pt;font-family:"Verdana","sans-serif"">HDT [2] stands for “Header, Dictionary, Triples” and is a RDF file format that compresses the data and comprises indexing. This allows for efficient exchange
and storage of RDF data as well as direct querying. Use cases are described at [2]. One example of usage would be the integration from a Triple Pattern Fragments Server [3].<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="font-size:10.0pt;font-family:"Verdana","sans-serif"">We will be happy to receive feedback on this experimental offer – posted to this mailing list or directly to me. Would you like to see this file format made
a permanent part of the service? We will decide on the next steps by the end of May.<o:p></o:p></span></p>
