Semantic Catalog A Zope 3 component that catalogs RDF information and stores it in to a configurable back-end storage. Query logic tools and expressions are used to query the storeage for semantic information. Zemantic requires rdflib and Zope 3. If you want to use the java visualization applet, you will need to install the graphviz package where the "dot" program is in the executable path of the Zope 3 *server*. Look in the doc/ folder. Installing Zemantic Zemantic now has a distutils-based installer. To see a list of installation options, run: $ ../path/to/python setup.py install --help For a typical Zope3-based install, use '--home', e.g.: $ ../path/to/python setup.py install --home /path/to/instance which will install zemantic into the 'lib/python' subdirectory of your instance.
