2. Recommendations for a Framework ensuringInteroperability, Reusability, & Composability

3. A Framework for Interoperability, Reusability, and Composability • Without the necessary management processes, technical solutions are point solutions in time only valid until the next change (update, upgrade, etc.) • Alignment of Management is necessary • To Enable meaningful interoperability on the simulation system level, composable models on the conceptual level are necessary • Common Conceptual Modeling is necessary XMSF/X3D Overview, JSB Technical Briefings

4. Recommended Solution for JSB • Three columns of JSB • An overarching Engineering Approach applicable to existing and future simulation components including migration concepts; • Establishing a Resource Repository comprising these Components and the necessary Meta-Models; • Alignment of the Management Processes XMSF/X3D Overview, JSB Technical Briefings

5. JSB Column 1 – A Common Engineering Approach • Requirements for the Integration Framework • Support Future Emerging Simulation Needs • Applicable for Future Components • Migration for Legacy Components • Supporting Integration of Real World Components(C4ISR, Platforms, Sensors, etc.) The JSB Integration Framework must be a conceptually stable solution independent from technical implementations, but commercially supported XMSF/X3D Overview, JSB Technical Briefings

6. JSB Column 1 – A Common Engineering Approach • Recommended Backbone – Application of the Model Driven Architecture (MDA) of the Object Management Group (OMG) • Implementation independent Modeling based on the Unified Modeling Language(UML) • Implementation independent Data and Object Modeling based on the Common Warehouse Meta-Model (CWM) • Implementation independent Repository Description based on the Meta-Object Facility (MOF) The MDA embraces technical implementations and standards, such asweb services, XML, EJB, SOAP, CORBA, etc. XMSF/X3D Overview, JSB Technical Briefings

7. JSB Column 1 – A Common Engineering Approach • The model hierarchy of the Model Driven Architecture (MDA) • Platform Independent Model (PIM); conceptual model resulting from requirement analysis (“What to model”) • Platform Specific Model (PSM); implementation oriented version (“How to implement”) • Code/Implemented Component PIM PSM Code The MDA connects conceptual and implementation level of the components => Bridging Management and Implementation XMSF/X3D Overview, JSB Technical Briefings

8. JSB Column 2 –Resource Repository XMSF/X3D Overview, JSB Technical Briefings

9. JSB Column 2 –Resource Repository • The Resource Repository must comprise not only the component, but also the meta-data describing the component on the various levels of interoperability • Recommendation:Use the MDA as the Framework for the JSB Repository • Component as Code (executable) • Include PSM (“White Box” of implementation without having to enforce open source) • Include PIM (Contribution to the Common Conceptual Model) • Gradual Development of a common conceptual view of the mission space of JSB XMSF/X3D Overview, JSB Technical Briefings

10. JSB Column 3 –Aligning Management Processes Common Data Engineering as the first Step: • Data Administration – Managing Information Exchange needs, I.e., which data are where in which format WSDL and UDDI support Data Administration • Data Management – Managing of unambiguous interpretation, I.e., which data mean what C2IEDM/Generic Hub support Data Management • Data Alignment – Managing of mapping of data sources to data targets, I.e., is all necessary data available XML enables efficient Data Alignment • Data Transformation – Technical mapping of source data format to target data format XSLT enables Data Transformation XMSF/X3D Overview, JSB Technical Briefings

11. JSB Column 3 –Aligning Management Processes • Each project must be embedded into the overarching JSB processes • Each project reuses JSB components (mandatory) • Each project contributes to the JSB components (at least on the conceptual level by adding with its PIM to the Common Conceptual View of the JSB Mission Space) • All projects are orchestrated by an Overarching Integrated Product Development Team • JSB orchestrates the heterogeneous implementations by aligning conceptual contributions to enable homogeneous training and support to operations XMSF/X3D Overview, JSB Technical Briefings

12. Initial Recommendations • What is necessary to enable a fast JSB start avoiding running into dead ends? • Use open standards in an orchestrated way • Establish an independent advisory board • Document management processes for evaluation and deriving of a guide • XML Namespace Management as a requirement for common data engineering • Start to develop PIM for the Common Conceptual View of the JSB Mission Space • Participate actively in open standard communities efforts for JSB (OGC, OMG, SISO, W3C, Web3D) XMSF/X3D Overview, JSB Technical Briefings
