Service registration and discovery in a domain-oriented UDDI registry

As a part of Web services triangle architecture, UDDI Registry takes on the task of service registration and discovery, which plays an important role in the open, distributed and dynamic Web services environment. However, the current UDDI Registries cannot meet the needs of practical applications. This paper proposes a domain-oriented UDDI Registry architecture and addresses some new concepts such as service property schema, service relationship and service constraint. Compared with other extended UDDI Registries, this architecture can improve the usability and operability of UDDI Registry a great deal, fulfill the requirements of some applications more friendly and thus is very suitable for some specific domains.
