GraphDB-Enterprise is distributed as a ZIP archive, which contains GraphDB compiled jars, all required libraries, configuration files, documentation, sample code and data. Use of the rule-compiler (i.e. custom rule-sets) requires the Java Development Kit (JDK) version 1.6 or later, otherwise a Java Runtime Environment (JRE) version 1.6 or later is required.
GraphDB-Enterprise uses Sesame as a library, taking advantage of its APIs for storage and querying, as well as the support for a wide variety of query languages (e.g. SPARQL and SeRQL) and RDF syntaxes (e.g. RDF/XML, N3, Turtle). The development of GraphDB-Enterprise is partly supported by SEKT, TAO, TripCom, LarKC, and other FP6 and FP7 European research projects.
