* *Dynamic configuration and automatic synchronisation* allows nodes to be added or removed at any time;
* *Notification mechanism* allows clients to react to statements in the update stream for the entire cluster.

* *Solr and Elasticsearch connectors* - provides extremely fast normal and facet (aggregation) searches; has the additional benefit to stay automatically up-to-date with the GraphDB repository data.

GraphDB-Enterprise is available under an RDBMS-like commercial license on a per-server-CPU basis; it is neither free nor open-source. To purchase a license or obtain a copy for evaluation, please contact [GraphDB-info@ontotext.com|mailto:GraphDB-info@ontotext.com].

h1. Installation and Usage

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.
The [installation section|GraphDB-Enterprise Installation Guide] of the user guide provides all the information necessary to set up an GraphDB-Enterprise cluster.

h1. Credits

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|http://www.sekt-project.com/], TAO, [TripCom|http://www.tripcom.org/], [LarKC|http://www.larkc.eu/], and other [FP6|http://cordis.europa.eu/fp6/] and [FP7|http://cordis.europa.eu/fp7/] European research [projects|http://www.ontotext.com/resources/].
