Subject: re: [egov] ebXML and web services
Paul, I share the vision here - and we've been working hard to put this common model into place. I just authored an article on this for ebxmlFourm - http://ebxmlforum.com discussing what Core webservices consist of. And further more the OASIS BCM and CAM teams are both developing work in this area. Notice that a WSDL definition for a CAM processor, using metadata out of either ebXML or UDDI registry - covers off the transaction processing as a webservice, or a local processor, however you want to configure it. So your transaction processing flows thru ebMS, with process definitions in either BPSS, BPEL or both, and then any content management is handled by CAM. There's one other piece to this - choice points - and that is the area the BCM folks are working on. More on this soon. Cheers, DW. =============================================================== Message text written by "Paul Spencer" > I have recently been thinking more about overall architectures for e-Government. Most architectures need a combination of transactions (such as the ability to file a tax return) and simple services that will be used by interoperating systems. An example of the latter might be the need to transform a name from the Extensible Name Language to/from a local format or to look up a postal address based on a unique property reference. It seems logical (to me at least) that the transactions would use ebXML and the services would use SOAP/WSDL. Treating each separately, the ebXML part would need an ebXML registry in which would be stored business process specifications and CPPs (among other things). Typically, the services would use a UDDI registry. Does anyone have experience of having these working together or of combining them? And what about combining SAML into this? I see this as totally independent, but others might have different views. <
