2 Agenda Approach to Inter-agency Information Sharing NETE Technical Capabilities Process for Shared Understanding Development Semantic Metadata Catalog and Portal Semantic Mediation Bus NETE Transition Task Proposed Deployment for NETE Components Going Forward: Inter-agency Access to SWIM 2

3 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 3

4 Inter-Agency Information Sharing Challenges Weather Community Integrated Surveillance Community UAS Community Flight and Flow Community Safety Community Airport Operations Community Airline Operations Community Other Communities Services conform Weather Flight Track publish Standards AXIM WXXM FIXM WCS WFS WMS KML GML ebxml UDDI SAR Other Services Time Data Classificat ion Geospatial Coverage Live Recorded Other Standards Temporal Coverage Simulated State/Local Government Commercial Entities International Partners 4

5 Example Scenario: NAS-GIG Service Federation GPS Satellite ADS-B NAS Track FAA Format DOD Format Track GIG BCSF FAA Operator DoD Operator ASDE-X NAS Data Source Consistent, Real Time Information DoD Data Source C2GF Operational Capability NOAA Technology Infrastructure System Wide Information Management (SWIM) DoD Data Services Environment (DSE) NAS Service Registry and Repository (NSRR) Semantic Discovery Metadata Registry (MDR) NAS Enterprise Messaging Service (NEMS) Semantic Mediation NCES Enterprise Messaging Federal Telecommunications Infrastructure (FTI) Network Connectivity Non-secure Internet Protocol Router Network (NIPRNet) Secret Internet Protocol Router Network (SIPRNet)? 5

6 Process for Shared Understanding Development If Air Force Weather Service and NNEW use different terminologies, how can we document the common business concepts? 6

7 NextGen Ontology Portal Purpose: To be a collaborative web application through which users can publish, access, search, browse, map, and update ontologies and their terms. Reference Implementation only Supports: COI participants (e.g., ontologists, SMEs, and enterprise architects), developers and managers. Example Portals National Center for Biomedical Ontology BioPortal Air Force Vocabulary OneSource Marine Metadata Interoperability Ontology Registry and Repository Open Biomedical Ontologies Foundry 7

8 Semantic Metadata Catalog and Portal An NNEW service is tagged with the keyword Hurricane, will a Air Force user looking for Cyclone services find it? Both Corridor Integrated Weather System (CWIS) and Integrated Terminal Weather System (ITWS) provide weather data, how does a potential DoD consumer decide which one to use for a particular purpose? 8

9 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 9

10 Technology in Action: NETE Demonstrations Web Services Layer Integration Layer Weather Community AF Electronic Systems Center Service descriptions from registry will imported for inter-agency discovery. ebxml NOAA NET NOAA Registry Integrated Surveillance Community Alion NETE Lab NETE Dashboard Semantic Metadata Portal Ontology Portal Semantic Metadata Catalog and Portal Semantic Process Layer Artifact Catalog FAA WCS WFS WMS NAS Service Registry Data Source FAA/National Security Display Demo Control JPDO User Interface Layer Semantic Metadata Catalog NNEW Web Coverage Service RI 3-D Radar Mosaic Mock Services R&D Domain FAA Emergency OPS SWIM ASDI EON Dashboard DEX ASDE SMDC GIIEP For Discussion One Purposes Year Challenge Only Demo 1 Other Services will be entered into the Semantic Metadata Catalog through User Interface. Demo 2 NASA LaRC Timing External/Future HWDS 10

11 Semantic Mediation Bus We have developed ontologies. Can it help implement system integration solutions, quickly? Can Semantics help reduce service development cost? How I can leverage my investment in SOA infrastructure for Semantic Interoperability? 11

12 SOA Silos Airline Code Lookup Table Data: UA User Flight Track Display 1 Human Communication FAA Flight Track Web Service HR Army Reference Field Name: Commercial Flight Data: AF SME 2 Custom Mapping AF Flight Track Web Service Field Name: Flight of Interest Data: United 122 Developer Custom Development 2 3 System Integration Custom Mapping SME Other Data Provider HR Army HR Marine Field Name: FlightID Data: UA122 Excess time is spent interpreting data from different sources despite the usage of advanced IT techniques like Web Services 12

13 Semantic Mediation Bus (SMB) An ontology-based web services mediation component that enables services with different message formats to interoperate Embedding in an Enterprise Service Bus (e.g. SWIM Enterprise Messaging Service) enables runtime semantic mediation within traditional SOA infrastructure, creating a Semantic Mediation Bus TM Common Ontology Enterprise Service Bus Semantic Mediator Semantic Mediation Bus TM Registry/ Repository Semantic Annotation Message Schema Mapping Web Service Proxy Semantic Lookup and Interoperability Assessment Metadata Management Protocol Adaption Message Transformation Message Routing Security Service Discovery Traditional SOA infrastructure Semantic Mediation Infrastructure Semantic Mediation Bus is a trade mark of Alion Science and Technology Corporation.

20 SOA: Benefits and Limitations Service Oriented Architecture (SOA) Key Benefits: Provides standards based mechanism to access Services at the transport and protocol level Promotes re-use of existing services Enables fast adaptation to business needs Aligns information resources to business goals Limitations: Current Web Service standards provide the syntactic description of the service interface, but do not describe the meaning or the semantics of the data or behavior. Hence the consumer of the service; whether another service or a human, needs to have intimate knowledge and awareness about the data and its elements Current Enterprise Service Buses (ESBs) don t have an out of the box ability to perform Semantic Mediation, that is the transformation and co-relation of data elements and services based on a pre-defined vocabulary Manual intervention and deep domain knowledge is required to develop custom mappings to correctly use data exposed by these related but different Web Services 20

21 Semantic Web Technologies Semantic Web (aka Linked Data or Web 3.0) is a set of W3C standards and technologies designed to allow machines to understand the meaning of the information on the WWW Standards-based Open-source tools Agent-based distributed computing paradigm Web Oriented Architecture Agile Development, improved interoperability Semantic Web in the Enterprise: A tool for knowledge discovery and management Common Vocabulary Open Linked Data Intelligent Searches Semantic Web in the Industry US government and leading social network companies have been implementing semantic-driven solutions Source: Tim Berners-Lee: Semantic Web and Linked D 21
