Joseki: The Jena RDF Server =========================== http://www.joseki.org/ Andy Seaborne andy.seaborne@epimorphics.com Joseki is a server implementing the SPARQL protocol. SPARQL (query language and protocol is the product of the W3C RDF Data Access Working Group (DAWG). Joseki is part of the Jena RDF framework. Joseki is open source under a BSD-style license. Working Group home page: http://www.w3.org/2001/sw/DataAccess/ Documents: Joseki3 provides SPARQL as the protocol and the main query langauge. Joseki3 is not compatible with Joseki2. The differences in architecture aren't huge but there are many minor differences but the objective of Joseki3 is to provide all the new features of SPARQL. Porting from Joseki2 ==================== Client Libraries ---------------- The client library is part of ARQ, an implementation of the SPARQL query language for Jena. http://jena.hpl.hp.com/ARQ ARQ is included in the Joseki download. Inference Models ---------------- Joseki hosts models provided by Jena2, including inferencing models: data can be combined with an OWL ontology or RDFS vocabulary description to produce an RDF model that has both ground and inferred statements. Query is then used to access the model. The Download ------------ The main directory is Joseki-. Servers run in this directory to find auxiliary files. The main sub-directories are: + lib/ - JARs needed + bin/ - scripts (check before use) + etc/ - configuration and various support files + doc/ - a copy of the online documentation + webapps/ - Joseki is a web application Running Examples ---------------- A simple server can be run by: 1/ Add all the JARs in lib/ to the CLASSPATH 2/ Run java -cp joseki.rdfserver joseki-config.ttl For more details on configuring and running a server, see: http://www.joseki.org/documentation.html Documentation ------------- The website http://www.joseki.org/ describes Joseki and provides documentation on server configuration and on the client library. It also includes examples of access using common, unmodified applications like wget. Details about the use of HTTP GET, how to create query language processors and how to add modules for data-specific fetch operations can also be found on the web site. A copy of the web site is in the doc/ directory of the download. Support ------- Please send questions to jena-dev@groups.yahoo.com Development ----------- The Joseki development project is hosted by SourceForge: Project: http://sourceforge.net/projects/joseki CVS: http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/joseki/ It relies on other open source software: JUnit, Jetty, Jena (which uses Xerces, Log4J, ORO, util.concurrent)
