Hi again,

I'm just looking at the existing  WCS bindings you linked to.  The binding 
classes I've looked at all seem to be unchanged since they were generated.  Did 
you only implement the ones you were interested in? If so, which ones?

Also, how do you handle the WCS versions when generating the bindings?  I can't 
see any mention of the version in these bindings, but surely different versions 
will generate different bindings?  I am assuming that I would need to generate 
them for each version of WCS I wish to implement, but can see how this could 
quickly become confusing because many of the bindings will have the same name.

Thanks,

Jon

Actually OGC used "http://www.opengis.net/wcs/1.1.1"; for the 1.1.1
corrigendum, and in the second corrigendum they took that back
and now the schemas for 1.1.2 say "http://www.opengis.net/wcs/1.1";.
GeoServer implements 1.1.1, the second corrigendum is only a few
months old and we have no sponsoring on the WCS side.

The pain was due to the fact the schema was split among many
files, but there were other issues thought. I could not figure
them out and asked you. Don't remember exactly what we did.

Anyways, the exiting bindings are here:
http://svn.geotools.org/branches/2.5.x/modules/extension/xsd/xsd-wcs/

but we only ever used them to parse request and encode
the responses, not the opposite (generate requests, parse
the responses). Afaik they are mostly plain jane EMF
based, so they should work both ways, but they were
never tested from a client side.

You can also have a look at the code in the GeoServer WCS 1.1
implementation here:
http://svn.codehaus.org/geoserver/branches/1.7.x/src/wcs1_1/

Cheers
Andrea
