ebXML recently adapted SOAP into the Messaging Specification,
which encompasses a set of services and protocols that allow an
electronic business client to request services from electronic business
servers over any application-level transport protocol, including SMTP, HTTP
and others. ebXML defines a general-purpose message, with a header that
supports multiple payloads, while allowing digital signatures within and among
related messages. Although the header is XML, the body of the message
may be XML, MIME, etc
A similar proposal is underway to use the UDDI business registry
to search for an ebXML Registry/Repository.
Anyone with UDDI expertise care to comment?
