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

7I n t e g r i t y - S e r v i c e - E x c e l l e n c e

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
