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.

 

The initial concern of the ebXML committee was 
defining standard message formats for electronic business (for example defining 
the standard parts of an invoice). As part of this standards effort it was 
obvious that the different artefacts needed to be registered; that is, there 
needed to be a place where you could discover that an invoice had been defined. 
But registration alone was not enough, it was also necessary to have somewhere 
to store the definition – commonly known as a repository. The committee 
recognised that if the whole lifecycle of an artefact was to be managed then the 
registry and the repository had to be joined at the hip. If they were not, it 
would be possible for a change to an artefact (for example, the addition of new 
field types in the invoice) to be implemented without the registry being aware.
