Copyright OASIS, 2001 Now that ebXML specs are available... Do I have to choose between EDI and ebXML? How does ebXML fit into web services? How does ebXML work in relation to other standards such as UDDI, SOAP…? Who’s implementing ebXML now? Is ebXML going to replace industry specific vocabularies? Can I implement some ebXML specs and not others? What’s next?
Copyright OASIS, 2001 Do I have to choose between EDI and ebXML?
Copyright OASIS, 2001 “ebXML is not a replacement for EDI. Large companies that have spent billions developing EDI systems can run those in parallel with ebXML. ebXML allows large companies to trade with smaller partners who don’t have EDI.”
Copyright OASIS, 2001 No business communicates solely in its supply chain EDI Limited to large organizations High cost-of-entry Rigid message sets Used by 5% of enterprises outside the Fortune 1000 ebXML Takes advantage of cheap Internet technology Built on EDI experience with input from EDI community Preserves EDI investment Designed for the other 95%
Copyright OASIS, 2001 How does ebXML fit into web services?
Copyright OASIS, 2001 “ebXML, SOAP and XHTML have emerged as technologies likely to provide the foundations for future Web services.”
Copyright OASIS, 2001 Web Services Step 1: Description – WSDL – ebXML CPP Spec and ebXML Business Process Spec Step 2: Publication and Discovery – UDDI – ebXML Registry Spec Step 3: Invocation – SOAP over HTTP – ebXML Messaging Spec integrating SOAP, HTTP
Copyright OASIS, 2001 WSDL and ebXML CPP WSDL provides: Service name Service parameters Endpoint for invocation ebXML CPP provides: Service name Service parameters Endpoint for invocation Role of an organization in the context of a service Error-handling Failure scenarios
Copyright OASIS, 2001 WSDL and ebXML BP WSDL identifies Business processes ebXML BP identifies Business processes Roles an organization must play Messages being exchanged
Copyright OASIS, 2001 “ebXML and UDDI are likely to end up as complementary solutions in E-business systems... UDDI should help accelerate the integration of systems used in marketplaces, while ebXML aims to standardize how XML is used in general business integration.”
Copyright OASIS, 2001 “Although ebXML does not rely on the UDDI service registry, instead providing one of its own, it does not exclude interoperability with UDDI, making it possible for businesses to locate ebXML-ready services through UDDI registries. Because ebXML goes beyond UDDI to include key data for building b-to-b partnerships and transactions, there's a clear advantage to its use.”
Copyright OASIS, 2001 UDDI and ebXML Registry Spec UDDI Basic identification Industry classification Technical capabilities ebXML Registry Spec Basic identification Industry classification Technical capabilities Search capability Retrieval of objects in corresponding repositories NOTE: ebXML offers a way to use UDDI to locate ebXML registries
Copyright OASIS, 2001 ebXML Messaging Spec and SOAP ebXML uses SOAP with Attachments, wrapping XML SOAP format in MIME envelopes MIME envelopes allow SOAP/ebXML messages to include non-XML content such as digitized images or programming code as attachments

Copyright OASIS, 2001 Is ebXML going to replace industry specific vocabularies?
Copyright OASIS, 2001 “ebXML provides a platform on which to build standards that are developed faster and yet supported by a rich set of software tools.”

Copyright OASIS, 2001 “Unlike the general category of Web services, which has seen its share of vendor adaptation, ebXML has been successful in attracting the support of industry heavyweights across all industries.”

Copyright OASIS, 2001 ebXML Moving Forward ebXML specs are complete and publicly available. ebXML integrates SOAP and seeks convergence with other standards. ebXML is being adopted by standards groups around the world including RosettaNet, GCI, Covisint, OAGI, OMG, OpenTravel Alliance, HL7… ebXML products are being announced daily by companies that include Bind Systems, XML Global… UN/CEFACT and OASIS jointly support ebXML.

Copyright OASIS, 2001 “With its long list of provisions, from security and messaging to workflow processes and QoS (quality of service) agreements between trading partners, ebXML is shaping up to provide the most comprehensive way to advance e-business integration.”
