Subject: RE: [soa-rm] Definition of "Service Consumer"
Using the publish/find/bind framework of SOA... The entity that publishes is certainly not the consumer. The entity that finds may or may not be the consumer but the entity that binds is certainly the consumer. So an entity that "binds" with a service would be the closest to a service consumer.

The reason that this distinction is important is similar to the distinction between a service interface and the service itself: accessing your bank account from an ATM or on-line will use different interfaces but ultimately all use the same service. Here is an example of why its important: the appropriate business logic to apply to a service request will depend on many factors: the means by which the request was delivered, the request itself and the person (or persons) for whom the request was made. This last aspect is completely independent of mode of requesting and is purely business/application specific. Incidentally, the above definition: "an agent that interacts with a service in order to achieve a goal" seems to be a reasonable definition of a service requester.
