<Excerpt> UDDI uses UUIDs and those UUIDs are specific to some particular registry. </Excerpt> Absolutely true for UDDI V2, in which key values were expressed using a URI format that starts with the characters "uuid:" followed by a formatted UUID. In UDDI V3, keys are of datatype anyURI. V3 also supports publisher-assigned keys, in which a publisher is permitted to propose a new key for an entity, and - given the policies of the registry - that key and the entity associated with that key may be inserted into the registry.
