Service requesters can send requests as SOAP messages
to the service registry to discover a service provider for obtaining goods or services.
Upon finding a potential business partner, the service requester can easily integrate
with a service provider to start an e-business. Table 1 provides an overview of the
main UDDI inquiry functions. Inquiry functions are further subdivided into two
groups: find_xxx functions provide general search functionality, whereas get_xxx
functions retrieve full records based on unique key values.

services for Web services discovery, or to design extension frameworks for the
UDDI registry. In the following section we will present some extension works for
Web services discovery.
