UDDI inadequate for SOA
Universal Description, Discovery and Integration (UDDI) is the registry standard from the Organisation for the Advancement of Structured Information Standards (OASIS) and is well supported by IBM, Microsoft and others. The intent is that it should be used to register web services and, as its name implies, the registration will create a standard description, which will enable services to be discovered and then integrated together. There is no doubt that such a service is necessary to support a System Orientated Architecture (SOA) and early implementations have used UDDI to good effect.
The problem is that the standard does not appear to be sufficiently broad to support the management and governance of the full range of artefacts needed to implement SOA. This is the argument put forward by the ebXML (electronic business using eXtensible Markup Language) technical committee, which has developed a series of OASIS standards.
