Towards High Integrity UDDI Systems

The basic idea of a ubiquitous service market where services can be published by their providers and discovered by potential users is - besides increased interoperability - one of the driving forces behind the SOA vision. However, the failure of the famous UDDI Business Registry demonstrated that service-orientation per se does not solve the problems related to the operation of such service registries - a problem well-known from the component-based development community. On the contrary, since services are highly volatile it is even more difficult to effectively manage a repository. In this paper we discuss the challenges associated with the operation of service brokering solutions with a clear focus on automation and integrity of the overall system as well as the offered search capabilities. To address the identified challenges we propose an extended UDDI architecture.
