  1. usw-xml Next-Generation USW Interoperability using Extensible Markup Language (XML) 18 October 2005 Don Brutzman Modeling, Virtual Environments & Simulation (MOVES) Institute Naval Postgraduate School (NPS) Monterey CA Mike Grimley NAVSEA Warfare Centers - Newport Newport RI

  2. Background • Sponsored by NAVSEA PEO IWS for Undersea Warfare Decision Support System (USW-DSS), Fleet ASW Command for A-TAS, and others • Formed in order to support USW efforts to establish coherent battlespace visualization capabilities for network-centric undersea warfare • Creating a harmonized DON XML NDR compliant superset of existing USW tactical vocabularies

  3. Outline • Charter and motivation • Organize for success • usw-xml products • Project exemplars • Planning ahead

  4. Charter • The usw-xml working group is improving Undersea Warfare (USW) interoperability using Extensible Markup Language (XML) tagsets for system data interchange. • Cooperative collaboration between many stakeholders is needed to achieve good interoperability.

  5. Motivation • Many XML technical capabilities enable significantly improved capabilities for • USW system interoperability • Connecting legacy systems, diverse partners • USW Decision Support System, other projects • We expect this work to broadly benefit the Navy, industry and scientific community.

  6. How to connect already-built systems • Keep internal data model • Often can’t change internals easily anyway • Map to shared, external data model • Build data/message converters that wrap inputs/outputs of established/legacy system

  7. Motivation Currently

  8. Motivation Short term

  9. Motivation Long term 0 Translators/Stylesheets

  10. Process for creating common vocabulary • Develop a common view (and description) of the world. • What objects/classes exist in C3S world? • What properties do objects/classes have? • Agree on the representation of these objects. • obtw XML • Evaluate the data/information needs of your particular application/message. • Update model if necessary

  11. Archiving data is increasingly important • “Old” legacy programs not really maintainable • Past capabilities either repurposed or lost • Not a showstopper problem with source code, but collected data is collateral damage • Archiving data in well-structured, well-defined format keeps it accessible and usable • Even by programs that aren’t written yet

  12. Consistent messaging essential Consistent APIs feasible Human Systems Interoperability “stack” • Coalition • Joint • Battle group • Ship • System • Offboard robots

  13. Organizing for Success

  14. Sponsors • NAVSEA PEO IWS 5, Undersea Systems • USW Decision Support System (USW-DSS) program. • Carrier Tactical Support System (CVTSC) • Fleet ASW Command • Tactical Assessment Markup Language (TAML) for ASW Tactical Assessment System (A-TAS) • Other sponsors & participants are welcome. • Many programs represented by mail-list members • ASW C2 Requirements study lists ~18 candidates

  15. Participation • Forum for effective collaboration and shared effort • Voluntary contributions and dialog, mutually beneficial • Broad participation is welcome • Navy, Industry, Scientific community • U.S. military, civil service and defense contractors • Allied partners a future possibility, under review • Two levels of participation • Contributing participants, 1-2 teleconferences per week • Listeners: discussions on best practices, problem resolution, announcements of progress, new capabilities

  16. Mailing list Currently 96 members • Open subscription policy, moderated • Password protected (only distribute by voice) • Treat as For Official Use Only (FOUO) • Hosted by NPS on MOVES Institute server • mailto: usw-xml@MovesInstitute.org • List information: http://www.movesinstitute.org/mailman/listinfo/usw-xml • Email archives: http://www.movesinstitute.org/pipermail/usw-xml

  17. Website • Password protected (only distribute by voice) • Access control: For Official Use Only (FOUO) • Hosted by NPS on MOVES Institute server • http://web.nps.navy.mil/~brutzman/usw-xml.html • Project includes multiple web servers • support advanced XML server capabilities • support state-of-the-art technical experimentation • demonstrate exemplar configurations

  18. Website 2 • Calendar for events of common interest • Participating organizations and individuals are listed with contact information • SECRET server capabilities can be provided when needed

  19. Intellectual Property Rights (IPR) • Must be predeclared in order to enable effective group efforts • Otherwise long-running efforts might short circuit • Cannot afford tainting with IP/patent encumbrances • Participation requirement for Royalty Free (RF) use of any patented tech: • Follow guidelines of DoN CIO XML Working Group • Follow policy adopted from standards organizations (W3C, Web3D)

  20. Implementations and Open Source • Two implementations are usually needed to demonstrate interoperability • One version in open source is also usually a minimum requirement for interoperability • VRML-X3D experience • Commercial versions are OK, but not if a program is then “locked in” • because program becomes vulnerable, which is not in best interest of government (or industry)

  21. USW XML milestones 2004-2005 • Establish careful IPR policy • Issue call for resources (Spring 2004) • List XML schemas of interest • Comprehensive • What systems need what datasets/tagsets, including legacy systems without XML • Plan future at-sea exercise demonstrations

  22. USW XML milestones 2004-2005 • Solicited participation through briefs to DON BSC, C3S Developers Conference, and NDIA Conference • Compared tagsets of interest • C2IEDM compatibility judged feasible, next year • Used information requirements for ATAS – CVTSC communication as basis for usw-xml v1.0. (TAML) • Briefed members on ISO 11179 and ISO 15000 series specifications, which form the basis for the DON NDR. • Produced detailed comments on DON CIO XML Naming & Design Rules (NDR)

  23. Outreach • Connecting to multiple USW/ASW activities • Obviously we are already hard at work • usw-xml group welcomes specific participants to accept liaison responsibilities • Monitor other groups’ activities • Provide 2-way channel for information, action • Serve as group point of contact • Outreach is an ongoing activity

  24. References • Many! • Programs of record • XML, web services, specific tagsets • Best references of common interest are kept on website. Short summaries help. • Many resources support new efforts by building “path of least resistance”

  25. usw-xml Primary Product FY2005: TAML

  26. Tactical Assessment Markup Language (TAML) • Represents tactical track information, context • Consensus representation by group implementers • Supports multiple programs • ASW Tactical Assessment System (A-TAS) • USW Decision Support System (USW-DSS) • Carrier Tactical Support Center (CVTSC) • (Lots more system/community connections possible) • Integration, exemplar construction in progress • Web service already available from NUWC

  27. TAML schema excerpt

  28. TAML schema 2

  29. Sample TAML excerpt

  30. Planning ahead

  31. Project Goals 2006 • Determine what data & information is next • Participants assess what is important • Programs have interoperability requirements • CVTSC Data Models • Sonar is another good candidate • Continue to research, solicit and monitor existing vocabularies of interest to the usw-xml community. • Schemas currently used by DSS

  32. Project Goals 2006 (cont’d) • Consider integration of multiple tagsets • Componentized approach • Some may be non-Navy, e.g. SensorML • C2IEDM evaluation and harmonization • Ensure mapping between usw-xml and C2IEDM data models • Determine if any further maritime extensions are needed in the C2IEDM data model

  33. Weekly meeting • One hour meeting per week, each Tuesday • Time: 0700 Hawaii, 1000 pacific, 1300 eastern • Second meeting for developers each Friday • Audio bridge for call-in provided by NPS • Video teleconferencing (VTC) as well, when facilities and video bridge are available • NPS, NAVSEA DC. SPAWAR San Diego, Hawaii • Minutes posted to mailing list, kept online

  34. IITSEC 2005 • Interservice Interoperability for Training, Simulation and Education Conference • 28 November - 1 December, Orlando Florida • Weeklong demos of exemplar applications • Joint booth with NUWC Caruso team, NPS

  35. Conclusions • TAML 1.0 is a great shared asset • Tons of work already in progress • Where is the rest of the C4I community? • Collaborative approach is essential, since scope of technology & operational concepts is beyond any single player • Further scrutiny, participation and guidance are all welcome, we are “walking the walk.”
