Support for expert system rule processing and choreography. Using systems such as the OWL classifiers (Pellet, Fact++, Hermit), rule based expert systems (Jess, Drools), and work with RDF choreography languages (SPIN), the decision support system should be able to applied in a choreographed layered fashion.  Key to this process is a choreography engine which matches data with rules and a reasoning environment.  Because of the complexity of the reasoning requirements, the OWL 2 specification is required in order to support the Semantic Infrastructure requirements.

Integration with Service Registries. Since the artifact metadata provides definitions of data, the service registry provide the data access needed to process information.  If a given artifact is a service, the decision support system determines the necessary definitions to integrate a service into decision support for the gathering of data.
