1. 1 XMSF Workshop 8/19-8/20/2002 MOVES Institute, Monterey California Topic: Modeling and Simulation Chair: Katherine L. Morse, SAIC EXtensible Modeling and Simulation Framework

2. 2 Modeling & Simulation XMSF: Integrate with tactical systems to augment the joint common operational picture Be supported by a public library of useful reusable components providing rendering support and architectural hooks for visual simulations Incorporate time services supporting discrete event simulation, wide area routing, and exercise recording/playback Services will be first-class objects, meaning run-time extensibility even for future plug-in components

3. 3 Suggestions for Discussion Discuss the shared goal of bringing working M&S applications matching real world problems into tactical use. Discuss approaches for backwards compatibility to HLA/RTI and DIS technologies which don’t constrain emergence of new capabilities. Explore specific bridging approaches for HLA/RTI and DIS over web channels Discuss compatibility with the Joint Technical Architecture (JTA), http://www-jta.itsi.disa.milhttp://www-jta.itsi.disa.mil Explore integration of C4I systems to augment joint common operational picture Discuss approaches for playback capture Identify technology availability: immediate, near-term (1-2 years), likely (3-5 years),problematic

4. 4  Discuss establishment of 24 x 7 x 365 networked virtual worlds over DREN/Abilene/Web between NPS and GMU to show accessible/growing exemplars with network monitoring.  Identify approaches for gaining support of various service operational commanders plus OSD C4I and transformation agents as top-level sponsors.  Discuss business model and logistics of open-source implementations.  Identify models/scenarios for bottom-up demonstration of capabilities using scenarios of increasing sophistication and interoperability.  List contrary technical attributes/conflicts which ought to be avoided. Strategic Considerations

6. 6 Main Points XMSF interesting for different simulation types, some technological challenges Extend current standard (HLA) to fit the needs, fix the shortcomings XML can be very successfully used in supporting 3D graphics via the internet XMSF based on XML and X3D works great Start with common understanding Huge project no easy answers, more subgroups, but worthwhile, good start Lots of difficult M&S challenges need to be considered High level overview comparing aims ways means

7. 7 Open Issues What are performance and computation issues Scalability Level of service for varying platforms Graceful degradation Is XML always used for data representation or is it better used for meta-data representation Compressed streaming file formats How do we do time management in a highly dynamic environment Scheduling and synchronization New time management services may be required Reduce cost of authoring and automatically converting to another format, e.g. XML to X3D Composing multi namespace documents Near Term: 1-2 years Mid Term: 3-5 year Long Term: > 5 years

8. 8 Open Issues How do we integrate non-simulation functionality, e.g. network optimization Simulation control API Result analysis Compensating for missing data Extend and compose object models without bringing down the simulation “Always on” Ease of use for developers Debugging support Conversion between data standards Near Term: 1-2 years Mid Term: 3-5 year Long Term: > 5 years

9. 9 Open Issues Integrate existing web standards SCORM XML X3D SEDRIS H-Anim Meta data standards How do we leverage the existing 3D formats How are aggregation and composability done Authoring Archiving Selection – searching, directories, repositories Traceability and archiving Near Term: 1-2 years Mid Term: 3-5 year Long Term: > 5 years

10. 10 Open Issues Branding, licensing, and security of data Black boxing VV&A of extensions Interaction between developers and users in the standards process Supporting multimodal simulations Sound and haptics X3D How do we rapidly integrate HWIL devices and live components How do we reason about and integrate simulations with different TM mechanisms Near Term: 1-2 years Mid Term: 3-5 year Long Term: > 5 years

11. 11 Open Issues Standards that meet the needs of consumers, military, and industry Tradeoffs between scalability, ROI, ease of use, security The use of meta data for: Systems engineering VV&A Valuation of data Dynamic data acquisition Correlation of 2D and 3D models Georeferenced Need to know Security Perception-based modeling Area of interest Near Term: 1-2 years Mid Term: 3-5 year Long Term: > 5 years

12. 12 Open Issues Define migration path for legacy simulations How much of a development environment can we define interfaces to support Near Term: 1-2 years Mid Term: 3-5 year Long Term: > 5 years

13. 13 Use Cases – Key Opportunities NPSNET V – Entity Based Swapping behaviors and data models at run time Always on Server based < 60 entities OTB/JSAF/VR Forces/Combat XXI Multiple output formats from a single source 2D to 3D correlation Mapping between data standards Extension of meta data standards Logistics and communications Acquisition: sensor to shooter pairing PH/PK Near Term: 1-2 years Mid Term: 3-5 year Long Term: > 5 years

15. 15 Next Steps Define XMSF Disagreement about next steps in the absence of this definition Requires coordination w/other subgroups Define M&S vision for XMSF focusing on extensibility and composability What is its relationship to HLA and JMASS? What is its relationship to the JTA? Define XMSF customer base Identify XMSF stakeholders Identify other efforts we can leverage

16. 16 Summary Agreed upon open issues Scoped their difficulty Sketched use cases Still need to map open issues to use cases Defined next steps Some disagreement here about what XMSF is Action items XMSF working definition Glossary Framework diagram Open up XMSF web page to allow participants to post materials Subgroup email reflectors What’s the process for executing the next steps?
