The classes RDFConsumer and RDFUtil integrate dspace-rdf into DSpace. RDFConfiguration is used to centralize configuration properties used by more than one class inside dspace-rdf. The class RDFizer contains the command line interface. To see the online help you have to use the following command:

[dspace-install]/bin/dspace dsrun org.dspace.rdf.RDFizer --help |

The installation follows the normal installation of a DSpace source release. In addition you have to provide a Triple Store. You can use any Triple Store you like, if it support SPARQL 1.1 Query Language and SPARQL 1.1 Graph Store HTTP Protocol. If you do not have one yet, you can use Apache Fuseki. Download Fuseki from its official download page and unpack the downloaded archive. The archive contains several scripts to start fuseki. Use the start script appropriated for the OS of your choice with the options '--localhost --config=<dspace-install>/config/modules/rdf/fuseki-assembler.ttl'. Instead of changing into the directory you unpacked fuseki to, you may set the variable FUSEKI_HOME. If you're using Linux, unpacked fuseki to /usr/local/jena-fuseki-1.0.1 and installed DSpace to /var/dspace this would look like this:
| Code Block | language | bash
|---|
export FUSEKI_HOME=/usr/local/jena-fuseki-1.0.1 ; $FUSKI_HOME/fuseki-server --localhost --config /var/dspace/config/modules/rdf/fuseki-assembler.ttl |
...
The RDFizer is a command line interface administrators can use to convert the complete repository contents, some content specified by its handle or to delete data from the Triple Store. If the Triple Store is reachable the RDFConsumer converts data at the moment it is changed within DSpace so that the Triple Store should stay synchronized with the repository. You can get the online help by executing the following command:
| Code Block | language | bash

[dspace-install]/bin/dspace dsrun org.dspace.rdf.RDFizer --help |
