No modification to any existing code is required, and minimal configuration is necessary - the default behavior is sufficient for most apps, and can be enabled by

1. Placing the Django-RDF app source directory in the PYTHON_PATH
2. Expanding the ontology tarball into the Django-RDF/rdf/ontology/ directory
3. Adding INSTALLED_APPS, TEMPLATE_DIRS and SERIALIZATION_MODULES entries to settings.py
4. (Re)Running syncdb to generate the database schema elements for the RDF models
5. Running the "syncvb" command, to generate an RDF vocabulary from existing models

Syncvb will print a code snippet that can be pasted into settings.py if the SERIALIZATION_MODULES are missing.
