All -
I refer you to the ongoing efforts of the OpenGIS Consortium. The OGC is
dedicated to defining interface specifications for the geospatial industry
that promote interoperability. One of the current efforts is focusing on
using XML, XML Schema, and so forth for packaging spatial data. The
specification is called the Geography Markup Language (GML). Please visit
www.opengis.org for more information. There is a public section to this web
site.
Cheers
Carl Reed
