Re: [soa-rm] Architectural Scope of Reference Model

Francis:

Discovery is described in the WSA from W3C in section 2.3.3.1 very well.

"There are various means by which discovery can be performed. Various 
things — human end users or agents — may initiate discovery. Requester 
entities may find service descriptions during development for static 
binding, or during execution for dynamic binding. For statically bound 
requester agents, using discovery is optional, as the service 
description might be obtained in other ways, such as being sent directly 
from the provider entity to the requester entity, developed 
collaboratively, or provided by a third party, such as a standards body."

For something to be discovered, it must first be in a format that allows 
discovery to happen. That is the act of advertising it. Discovery 
happens ONLY after something is available to be discovered.
