Configuration
The RDF CP retrieves a single configuration setting in its ContextId via the Configuration API: "uri"
Example configuration using an XML configuration file:
<Configuration

Service
- The RDF CP does not require authentication materials. It assumes that anyone can retrieve the URI with the RDF data.
