Abstract

In the world of imagination built around Web services, the dream is that every software application is coded with a self-discovery and self-categorization method. UDDI and ebXML enables businesses to host on-line registries of available Web services. A business uses the UDDI TModel system or ebXML classification mechanism to classify the hosted Web service. And there lies the problem: Both ebXML and UDDI allow multiple taxonomies and expects self-policing for mistaken entries in the registry. Looking for a service in the on-line registry is like looking for a needle in the hay stack.

This presentation describes how a global reference model for classification of web services helps in their discovery and reusability. It identifies the criteria for a good classification scheme and proposal for a reference model that can be used globally for classification of Web services. It drills down into the functional specifics of a classification model for business processes that are registered as web services in a global registry that could be either UDDI or ebXML registry. It delves into the details of a few reference models that are currently in use by various industries world wide for classification of business processes. A comparative analysis is carried out and concludes with the proposed reference model.

This presentation also touches upon various business driven registry client interface services required for the management of web services. It reflects the standards based work being carried out under UN/CEFACT, OASIS and other standards organizations to this effect.
