VectorC has created several demonstration applications to showcase the functionality of the Semantic Service Bus and the potential of RDF-based solutions.

DBpedia & Google Maps Integration

This demo illustrates integration with a remote RDF repository (DBpedia) via SPARQL Protocol over HTTP. Mule services running in Apache Tomcat utilize the SSB Jena HTTP connector to execute remote SPARQL queries against DBpedia, an RDF repository generated from Wikipedia. Query results are transformed into JSON and displayed in a Google Map.

Pathways Explorer

This demo illustrates the power of linked data in the biomedical space via the traversal of the integrated RDF datasets stored in the Bio2RDF SPARQL repository. A GWT-based client application supports the retrieval of publications about genes involved in a specific metabolic pathway. This involves the following dataset navigation:

• A metabolic pathway is selected from the set of pathways defined in the KEGG PATHWAY database
• All of the genes involved in that pathway and their Entrez Gene specification are retrieved.
• The PubMed articles published about those genes are retrieved. The publication list can be limited to researchers belonging to a specific set of institutions.

CCR/HL7 CDA & NCI Thesaurus Processsing

This demo shows how the SSB can be used to execute complex semantic rules on electronic medical record data. In the demo, Continuity of Care Record (CCR) (supported by Google Health and Microsoft HealthVault) or HL7 Clinical Data Architecture (HL7 CDA) (supported by HealthVault) documents are transformed into RDF with codes mapped to NCI Thesaurus OWL classes. The generated datasets are stored in an RDF repository and then filtered based on semantic rules leveraging NCI Thesaurus-based inferencing to identify specific patient subsets.
