Background
XML – Extensible Markup Language: created so that richly structured documents could be used over the web
WS – Web Services: self-contained, self-describing, modular applications that can be published, located, and invoked across the Web
XML standardization on World Meteorological Organization (WMO) agenda for the May 2006 meeting.
United States environmental agencies (NWS, Navy METOC, AFW, etc.) undergoing separate developments of XML and WS

Purpose
Principal forum for developing, coordinating, and maintaining the national position on XML and web services for use with meteorological services
Specifically: Assess and document the current efforts toward establishing
XML and web services standards Assess feasibility and make recommendations for how and what
aspects of U.S. efforts should be aligned, coordinated, and/or merged
Develop the Federal position on XML and web services for approval by the CEISC and for presentation to appropriate U.S. coordinating bodies for advancement in the international meteorological community (WMO)

Status
XML development efforts at NWS and NCAR are capsulized
NWS has purposely done limited development in anticipation of a standard being implemented
NCAR is willing to adjust their XML to a future standard, provided it is well-documented
AFW and Navy METOC have developed the Joint METOC Broker Language (JMBL)
DoD is the lead in XML development for the Next Generation Air Traffic Control System (NGATS)

Status (cont)
Web Services: DoD is developing Services Oriented Architecture (SOA) and
Web Services as it implements Net-Centric Operations and Warfare (NCOW) and Global Information Grid (GIG)
Other agencies due to customer base have not investigated Web Services
Further exploration and collaboration required

Recommendations
JMBL used as the basis for the national standard in environmental product delivery
With the above concurrence, propose to the WMO that the United States lead the development of a XML standard

Future Actions
Expand membership of JAG as required
Baseline JMBL with input from stakeholders
Present body of work to WMO
Investigate feasibility of combining efforts in development of Web Services
Develop framework for implementation of Web Services
