Web Service Discovery Processing Steps.
Wolfgang Hoschek · 2002
The most straightforward but also most inflexible configuration approach for invocation of remote services is to hard wire the location, interface, behavior and other properties of remote services into the local application. Loosely coupled decentralized systems call for solutions that are more flexible and can seamlessly adapt to changing conditions. While advances have recently been made in the field of web service specification, invocation and registration, the problem has so far received little systematic conceptual attention. In this paper, we outline seven web service problem areas and their associated processing steps, namely description, presentation, publication, request, discovery, brokering and execution. We propose a simple grammar (SWSDL) for describing network services as collections of service interfaces capable of executing operations over network protocols to endpoints.
