Rhizomer is a web application that facilitates publishing, querying, browsing, editing and interacting with semantic data.

More details are available from http://rhizomik.net/rhizomer/

Download and Install

The application plus the required libraries is available as a WAR file from the downloads section. The source code is available from the corresponding section.

Rhizomer has been just tested and is prepared to work with Tomcat. However, it can be installed in any servlet/jsp container by configuring the container managed authentication mechanism following the instructions for that particular container.

For Tomcat, the war should be placed in the webapps folder and it should be automatically expanded and installed as and application available from "/rhizomer" (typically "http://localhost:8080/rhizomer").

If installed elsewhere, you should just adjust the path to the users.xml file in the META-INF/context.xml file, currently "webapps/rhizomer/META-INF/users.xml". There is just one default user named "rhizomer" with password "rhizomer".

If you go now to the installed Rhizomer homepage, you will see almost the same content that is available from the running example at http://rhizomik.net. However, the semantic metadata used is locally stored as a file and loaded at start time from "metadata/rhizomikstore.rdf".

You can change it or configure a different file to load RDF from changing the "WEB-INF/web.xml" file. The Rhizomer servlet parameters specify if the RDF metadata is loaded/stored from a file (by defining folder and file name) or from a database (there are all the typical parameters for MySQL though other databases can be also used as long as they are compatible with Jena, the RDF store currently supported). There is also a connector for Open Link Virtuoso.
