FYI, the OpenGIS Consortium is presently starting to address these XML issues with vigor at both the service level (using UDDI, WSDL, SOAP) and XML file formats for data (using DTDs and XML Schema for Geographic Markup Language [GML], ArcXML [by ESRI], LandXML(?) [by someone else]). It would be wise of THREDDS to participate in or align with this process. -Jeff DLB Dr Jeff de La Beaujardiere NASA Goddard Space Flight Center * Code 933 address@hidden * +1 301 286 1569 Digital Earth * www.digitalearth.gov
