A flexible service selection model for enterprise distributed systems

A common problem in distributed systems is the selection of a particular service instance from a set of possible services. In this paper, we identify the kinds of information required to select services within enterprise distributed systems and present a flexible mechanism for selecting services. This mechanism enables clients to build complex queries that are able to utilise script-based interaction with service instances. The use of scripts allows the selection of particular services based on their internal state and permits services to tailor their responses based on the particular client.
