[mapserver-users] ArcIMS Gateway

[imap at chesapeake.net]

Bruno/list,

Somewhere on the ArcIMS machine, there exists an 
ArcXML DTD or schema which can be comformed to by 
writing some mapscript with XML::Writer.   I am 
working on a similar project, but is a mapscript 
query engine interface with OpenGIS GML
(anyone else using XML with the GML DTD)
I'd be glad to share notes, if you are doing
working along these lines.

The standardization of geospatial data transfer 
is a goal we should all be working towards. 

If anyone has the ArcXML DTD, please post.


Thanks,
