Subject Re: Making the SDO & SCA schemas available via internet
Date Mon, 08 Jan 2007 16:39:18 GMT
Hi Dan,

I've heard that a more general problem is that the namespace URIs that SDO 
uses for its standard types:

commonj.sdo
commonj.sdo/xml
commonj.sdo/java

are problematic since they are not absolute URIs and according to some WS 
spec are not really valid, so some web servers completely ignore them.

If that is true, then SDO is going to need to make a change to use proper 
absolute URIs for these namespaces. For example:

"http://www.osoa.org/2007/sdo"
"http://www.osoa.org/2007/sdo/xml"
"http://www.osoa.org/2007/sdo/java"

Then you won't need to include a schemaLocation, since the imported 
namespaces themselves will be available on the internet.

I guess the first step is to open an issue with the SDO specification and 
see what results.
