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

Sampson,

I am not a GML guru and I don't know if a binary version exists already, 
but I would imagine that HDF5 would be a excellent choice by its own 
hierarchical nature. I mean, we can use GML as a schema to store the 
data in binary format in the HDF5 format.

Best regards,

Ivan
