Metadata Discovery for a Service-Broker Architecture

UDDI (universal description, discovery and integration) is one of the main standards for describing, publishing and discovering services on the Internet. It employs a service-broker mechanism through service storage and registration. We will discuss the need for data enquiry services that are best published with their underlying metadata. In order to provide greater utility and expressivity it is proposed to represent the metadata in a Web ontology. This needs to be achieved within the UDDI so that such data enquiry services are easily accessible. We propose an extended template for publishing, registering and storing services that facilitates the discovery of metadata in a service broker architecture such as UDDI. Finally we illustrate the operation of this extended use of UDDI using existing approaches and standard technologies.
