An overview of the Web Services Inspection Language
Service discovery defines a process for locating service providers and retrieving service description documents, and is a key component of the overall Web services model. Service discovery is a very broad concept, which means that it is unlikely to have one solution that addresses all of its requirements. The Universal Description, Discovery and Integration (UDDI) specification addresses a subset of the overall requirements by using a centralized service discovery model. This article provides an overview of the Web Services Inspection Language (WS-Inspection), another related service discovery mechanism that addresses a different subset of requirements using a distributed usage model. The WS-Inspection specification is designed around an XML-based model for building an aggregation of references to existing Web service descriptions, which are exposed using standard Web server technology.

Finally we have a simple means of discovering when new services have been made available at a particular endpoint location. This article introduces and demonstrates the combined use of Atom 1.0 and Web Services Addressing 1.0 specifications as a functional replacement for the now defunct WS-Inspection.
