Transcript

  • 1. A Semantic SOA Approach toNextGen Information Sharing Wen Zhu, Alion Science and Technology Germaine Forbes, SAF/ CIO A6 / JPDO 26 Jan 2012 1
  • 2. Agenda• Mission• NextGen Information Sharing Challenges• Information Sharing Approach – Process – Technical Capabilities – Infrastructure• Demonstrations• Putting It Together• Way Ahead 2
  • 3. Mission Net-Centric Operations Division (NCOD) leads the Joint Planning and Development Office (JPDO), agency partners, and industry to realize information sharing capabilities to improve situational awareness, enhance decision making, and facilitate collaboration. Information Network Demonstration Experimentation Exchange Infrastructure Capability and Architecture, MeasurementProcess, Ontology Outreach 3
  • 4. Big Picture• Net-Centric Operations Division (NCOD) promotes policies and strategies for information sharing and coordinate investment and development of network-enhancing capabilities – Work to make the information understandable by: • Defining an ontology (or shared vocabulary) • Documenting required information exchanges • Provisioning services to improve discoverability, re-use, understandability – Work to make the information discoverable and accessible through • Service registry, Semantic Metadata Catalog and Portal – Help to identify accurate and timely data • Identifying Authoritative Data Sources, which provide accurate and timely data • Incorporating metadata about the accuracy and timeliness of data 4

  • 7. Information Sharing Approach • Repeatable process for developing shared understanding through definition of information elements across domains. • Technology capabilities stack that enables the information sharing vision of NextGen. • Services Oriented Architecture • Semantic Web Technology • Federated Ontology • Interagency infrastructure that employs the technology stack and information sharing approaches and validates them in a near-realistic environment. • Enables shared R&D • Addresses real-world info sharing obstacles • Identifies pathways to near-term operational improvements 7

  • 9. Process for Shared Understanding Development Transformation• Key Deliverables COI Ontology (RDF/OWL) Rules (XSLT) – COI Ontology Business Process Message Schema – Business Context (DoDAF Artifacts) Analysis (XSD) (OV-2) – Other Artifacts Information Service• Current Engagements Exchange Description Description (WSDL) (OV-3) – Weather Operational Activity Architectural – Integrated Surveillance Model Impact Report (OV-5b) – Unmanned Aircraft System Business Rules Requirements• Consistent with DoD Information Document (SV-4) Service Constraints ExchangeNet-Centric Data Architecture, Systems CommunicationsStrategy Process, Ontology Description (SV-2) 9

  • 11. Semantics Metadata Catalog and Portal SOA Registry Scope •Governed within an Agency •Focused on discoverability of published services •Supports only flat, non-semantic data •Focused on governance Semantic Metadata Catalog and Portal Extended Capabilities•Utilizes existing SOA Registry capabilities•Addresses cross-agency information exchanges•Facilitates collaboration•Focuses on discoverability of defined information exchanges•Takes full advantage of Semantic Relationships defined in ontologies Bottom Line: • Provides an intelligent search • Utilizes semantic discovery beyond simple keywords capabilities • Yields a more targeted result set 11
  • 12. Inter-AgencyInfrastructure 12
  • 13. InfrastructureNet-Enabled Test Environment (NETE)• Concept – Virtual test environment – no new facility – Government and industry participation – Experimental approach – test, measure, evaluate, adjust – Adopting existing projects; leveraging progress• Benefits – Data sets made available will bring interested developers – Allows demonstration of concepts to flesh out requirements – Allows trade-off studies for architectural decisions – standards, processes, TTPs, tools, infrastructure design – Tests Governance model for efficiency – Accessible to all NextGen participants; can link to outside data sources/consumers – Leverages work already done by NextGen stakeholders 13
