[OSGeo-Discuss] idea for an OSGeo project -- a new, open data format

  +1 for GML with BXML encoding as next open standard. GML 3.* with his
ability to be 'profiled' seems to be on the base of  almost all and
every OGC norm being proposed on last 2-3 years. As Rob Atkinson said to
me, BXML may be an encoding for GML, in a way no standard needs to be
modifyed to support this encoding, only implementors must add support to it.
    At gvSIG we're currently working both on a low level library for
reading and writing GML 3.* + other GML alike formats, disacopled of 
our object model, and a java port of this cubewerx BXML encoder/decoder.
We hope to release early results by the end of 1st term next year.
    Maybe the way of push the standard (both OGC and ISO) it's by simply
implement parsers and writers, and use it a widely as possible.
