RE: [wsrf] Singleton Resource Pattern

["Sedukhin, Igor S" <Igor.Sedukhin@ca.com>]

Steve,

 

Your example was interesting. How about this one:

 

Web Service implements a UserName property. Client sends a GetResourceProperty SOAP message with WS-Security headers containing X.509 certificate. Web Service returns the UserName after matching the certificate.

-- Is this a singleton or an implied resource pattern? One could claim that there is a user resource, however this interaction does not use WS-Addressing and moreover it would not be possible to build WS-RF qualified EPRs for such interaction.

 

The same use case could be modified to include UserDiskQuota property, and the same argument would apply.

 

It seems that whether it is an "implied resource" or an "implied singleton" has nothing to do with GetResourceProperty (GetProperty for that sake) operation. In other words use of WS-Addressing does not add any semantic value to the fact that one could retrieve a property by sending a message to a service.
