Project Goals
Focus on demonstrating the use of Semantic Web technologies in intelligence use.
- Connecting unstructured inputs to rich metadata
- Bringing in information from "open" sources - provenance
- tracking who entered the information
- tracking where the information came from
- Using (multiple) ontologies in OWL
- To help with annotation
- To organize information display
- To manage import/export of unstructured and semi-structured data
- Image and subimage annotation and display
- Demonstrating new information portal management tools enabled by the Semantic Web
Technologies Used
This project concentrates on the use of Semantic Web technologies
- The Web Ontology Language OWL
- RDF Databases
- RDF Query for page generation
- Equivalence and inverse inferencing
- Limited classification (OWL DL)
- RDF/XML syntax for data exchange
- RDF/N3 syntax for human readability
- Sem Web Integration w/standard Web tools
- HTTP protocol based (standard server software)
- Universal Resource Identifiers for web-based access
- XSLT and Perl for portal presentation (HTML-like view)

Future Work
Current Project focus is on showing "end to end" capability, future work will deepen the individual capabilities
- Other media: extend markup/display to NITF, speech, video
- Geo-registration: add time, space metadata to information
- Distributed Access/query: import/export of information to/from other "graph-based" repositories
- Policy Aware Web: new approach to access, privacy, rule-based security
- Semantic Web Service provision: WSDL for ontology and geospatial remote "query"
- Multi-view collaborative work: extend portal to tool APIs to remove central server
