  2. BEA & Service Oriented Architecture 1 SOA Challenges and Best Practices 2 Semantic and SOA 3 Agenda

  3. Review of Today’s Environments • Today’s environments are “liquid” • Changes must be made in moments, not weeks in order to satisfy changes in operational situations • Adapting to competitive changes • Re-tasking a mission for a new target of opportunity • Today’s environments are distributed • Impractical to require manual changes at each application • Impractical to redeployment for config/security changes • Today’s environments are non-stop • Changes can’t require restarts • Requirements for 24x7 becoming more common

  4. What is Service-Oriented Architecture ? “Service-Oriented Architecture is an IT strategy that organizes the discrete functions contained in enterprise applications into interoperable, standards-based services that can be combined and reused quickly to meet business needs.”

  6. What is Semantic Service-Oriented Architecture ? “The application of expert knowledge encapsulated in Ontologies and applied to the integrated knowledge of an Service Oriented Architecture”

  13. Semantic Layer (Data Services) Semantics Problem: A Schematic Data Service Layer makes two assumptions: • “User” knows exactly what they are looking for • “Fields” in data Source are defined and known Solution: Create a layer of abstraction which can • Express the semantic meaning of the data service • Enable semantic search of data service contents • Provide the ability to classify data source concepts with taxonomies • Provide the ability to relate concepts to each other with ontologies

  14. Reference Semantic Architecture for SOA (Today) Where a search for “WMD” in field1 in datasource 1 turns into… A search for “WMD”, “Chemical”, “BIO Hazard”, etc.. In field1 in datasource1, field2 in datasource2 etc..

  18. Semantics Semantic Layer (Messaging Services) Problem: Routing Rules within Service Buses are based on binary decisions: • “User” knows exactly what they are looking for Solution: Create a layer of abstraction which can • Understand and use service semantics to make routing decisions • Defer content-based routing decisions until unstructured text content has been processed and tagged • Look up services in a semantically aware Service Registry

  19. Reference Semantic Architecture for SOA (Future) Where a route to service 1 because field 1 in a message is “WMD” turns into… A route to service 1 because fiedl1 or field2 in a message is “WMD”, “Chemical”, “BIO Hazard”, etc..

  21. Semantics Semantic Layer (Registry Services) Problem: Dynamically consuming services through a service registry is constrained via data and meta data available in UDDI • “User” knows exactly what they are looking for Solution: Create a layer of abstraction which can • Understand and use service semantics to service decisions • Defer content-based routing decisions until unstructured text content has been processed and tagged • Look up services in a semantically aware Service Registry

  22. Semantic based Event Processing • Event Stream Processing (ESP) • Set of technologies for the support of event-driven applications (EDA) • Includes event visualization, event processing agent (EPA), inference engines, and complex event processing (CEP) • Event Processing Agent (EPA) • Runtime agent for event processing. • Includes an event processing engine, stream management, index management, etc. • Complex Event Processing (CEP) • Event processing language for the correlation of events into complex events • Includes the event processing language, and supporting tools such as compilers, and editors.

Titan KSC Spaceport DELTA IV Navy Atlas III Delta II Commercial Agencies Atlas 45 SW RTSC LOSC JBOSC SMC/RNP HQ AFSPC Delta ATLAS V 14 AF SLRSC CSSC Spacecraft EELV Titan Semantic Data Services at USAF 45th Space Wing The Problem: • Limited, inefficient enterprise data sharing • Limited, constituent-centric IT staff • Wide variety of legacy data source silos with different semantics (lexicons, concepts, …) • Structured, Semi-Structured, Unstructured information content

  24. Value of Semantic Data Services Wing Operations Center • Improved emergency response to threats and hurricanes • Automated situation reports (SITREP), checklist status aggregation Range Scheduling • Improved scheduler productivity - 6:1 for Range schedulers • Increased Range resource availability by hundreds of hours Infrastructure Interoperability and Re-Use • Infrastructure serving multiple applications

  25. Summary • Service Oriented Architecture is a journey • “Plan Strategically and Implement Tactically” • Semantically Aware Infrastructure that understands Semantically Tagged Services are the next steps on that journey • Semantic SOA plays a key role in providing increased scalability and interoperability of SOA architectures
