Resolving endpoints

[Ray Plante]

Hi Guy,

There is still ambiguity about what AccessURL points to in the case of Web 
Services.  In VOResource v0.9, it is defined to point to the WSDL; 
however, there was some desire for it to point to the endpoint for the 
reasons you described.  In the NVO registry, we didn't have a lot of 
Web Services defined (and that we critically depended on for our 
apps/demos), so it we were living with this ambiguity while we figured out 
what made sense.  

There are still some issues to address related to our discussion of 
standard WSDL definitions that will affect this question.  For example, 
would we need or allow different parts of the interface to have different 
endpoints?  If so, which one should be the "accessURL"?  Should the other 
endpoints be placed in the registry as well? (probably so; then 
additional metadata are needed.)   I'm doing some experiments now with 
Axis to test some of the ideas we've batted around.

cheers,
Ray
