4. February 7, 2003XMSF Early Adopters’ Workshop4 Agenda

5. February 7, 2003XMSF Early Adopters’ Workshop5 XMSF Motivation  Transformational technologies are needed to scale up defense modeling/simulation to meet real-world needs  Can we use Web technologies as common framework? Dynamic capabilities, open standards, Web business model provide lift to support government and commercial success Easy use and open extensibility for developers and users, fueling rapid growth of interoperable simulations Bring defense modeling/simulation/tactical support into mainstream of enterprise-wide best-business practices

6. February 7, 2003XMSF Early Adopters’ Workshop6 XMSF Precepts  Web-based technologies can provide an extensible modeling and simulation architecture, to support a new generation of interoperable applications  Simulation support is needed for operational warfighting capabilities  XML-based architecture can provide a bridge between emerging rehearsal/reality/replay requirements and open/commercial Web standards  Web = best tech strategy + best business case

7. February 7, 2003XMSF Early Adopters’ Workshop7 What Does XMSF “Look Like?”  Based on web and XML technologies  Data and metadata standards  Profiles: the adaptation of the design and implementation process for M&S over the Internet; profiles specifically include - The specification of mandatory requirements A tailoring of the set of selected standards (e.g. tailoring of authentication standards) Specialization of design methodologies (e.g. subclassing of generic classes) Recommendations and guidelines for implementation (e.g. composability guidelines, recommended technologies, technology application guidelines, recommended hardware configuration)

8. February 7, 2003XMSF Early Adopters’ Workshop8 XMSF Definition  The Extensible Modeling and Simulation Framework (XMSF) is defined as a set of Web- based technologies and services, applied within an extensible framework, that enables a new generation of modeling & simulation (M&S) applications to emerge, develop and interoperate. “M&S is the next killer app for the Web.” Dr. Anita Jones, XMSF Strategic Opportunities Symposium, 6 September 2002

9. February 7, 2003XMSF Early Adopters’ Workshop9 Technical Challenges Workshop  Monterey California USA, 19-20 August 2002 Preceding annual NPS MOVES Open House  Goal: initial technical survey and assessment Modeling & Simulation via Web technologies feasible? XMSF white paper provided basis for discussion Extend report for strategic planning  Diverse technical experts invited in 3 areas Web/XML, Internet/Network, Modeling & Simulation Point papers for undiluted snapshots of key ideas

10. February 7, 2003XMSF Early Adopters’ Workshop10 Technical Challenges Workshop Conclusions  Close working relationship across all three technical areas will continue to be needed  XMSF approach must be further refined from a high-level concept to definitive technical recommendations, practices, and applications  Need exemplar applications identified, initiated  Web Services appear to be a promising area for focusing future work  Security concerns are cross-cutting for all areas, must be addressed throughout design process

11. February 7, 2003XMSF Early Adopters’ Workshop11 Strategic Opportunities Symposium  Friday September 6, GMU Fairfax Virginia  Diverse speakers presented their considered opinions, in reaction to the workshop whitepaper  Keynote address by Anita Jones: “M&S is the next killer app for the Web”

12. February 7, 2003XMSF Early Adopters’ Workshop12 Strategic Opportunities Symposium Conclusions  Many common goals C4I plenary, Rob Walker DISA COE program manager C4ISR/Simulation Technical Reference Model report Navy night, Gene Layman NRL  Web interoperability can expose legacy systems without major retooling of internals Change connectivity challenge from N-N to 1-N  Semantic interoperability possible, via oporder messaging NPS exercising XML-MTF, Generic Hub (LC2IEDM), X3D, SVG NUWC can ingest same XML oporder into submarine CCS

13. February 7, 2003XMSF Early Adopters’ Workshop13 2002 Successes  Final report completed and available on XMSF web page  Several demos as I/ITSEC Videos coming up later in agenda  Planning events and papers for 2003 Web3D Symposium 2003 Spring SIW, 3/30/03 - 4/4/03, Orlando Florida 2003 Euro SIW, 6/16/03 - 6/19/03, Stockholm Sweden  Established mail lists xmsf-announce for occasional announcements xmsf-discuss for technical discussions www.movesinstitute.org/xmsf/xmsf.html to sign up www.movesinstitute.org/xmsf/xmsf.html

14. February 7, 2003XMSF Early Adopters’ Workshop14 The Road Forward  Establish liaison with key standards organizations  W3C BOF at W3C Symposium March 9-12  SISO BOF and focused paper session at Spring SIW 7:00 p.m., Monday March 31 Papers and possible BOF at Euro SIW Establish XMSF product development group?  Identify early adopter programs  Establish infrastructure for communicating progress, capturing results, and disseminating profiles  Define structure of profiles  Establish archive of results to date  Identify process(es) for standardizing best practices
