Some food for though, which may be relevant or not. 1) The state of an endpoint service in the registry. This would be needed for clients and also reporting. 2) Each service should be categorised, either via a hardcoding of type under the registry, or a spi provided categorization. This may lead to signatures like searchByCategory etc. 3) Policies per service, and optionally on a per category basis. 4) I'm not sure at what point we need to think of templating services for each category, so that clients may at least know what template to possible work to, the underlying service impl can be changed transparently. 5) Aside from just services, will the registry hold dependant objects such as an XSD if there is say a validation service? Would this be classed as a ServiceResources and be grouped under the ServiceEntry such as ServiceEntry.getResources() ?
