ebXML: Moving Forward- Technical OverviewPatrick Gannon

President & C.E.O.

ebXML enables anyone, anywhere

to do businesswith anyone else over the Internet

ebXML Provides a Standard Way to:

• Exchange business messages

• Conduct trading relationships

• Communicate data in common terms

• Define and register business processes

ebXML History

• Begun as 18-month initiative in November 1999

• Specifications delivered on schedule in May 2001

• Developed in an open process by more than 4500 participants representing 2000 organizations in 150 countries on virtually every continent

• United Nations Center for Trade Facilitation and Electronic Business

• Developers of EDIFACT

• One of four organizations in the world that can set de jure standards

• World’s largest independent, non-profit organization dedicated to the standardization of XML applications

• More than 400 members in 26 countries

What does ebXML do?

• Lowers the cost/complexity of electronic business

• Facilitates global trade and puts SMEs and developing nations in the picture

• Expands electronic business to new and existing trading partners

• Converges current and emerging XML efforts

• Eliminates dependence by supporting any language, any payload, any transport

ebXML metamodel in a staged approach

• You may use TRP section without the rest

– To exchange your own message structures via TRP

• You may use Information section without the rest

– To define message structures to be used in some other TRP

• You may use Process section without the rest

– You may optionally define contract semantics of a process

• You may use Market section without the rest

– To create an independent set of yellow or white pages

• Or: - Use all of them to reach the full vision of ebXML

Trading-Partner Agreement

Mission• Define a specification for creating

the IT part of a partner profile and a TPA, which is a combination of two partner profiles

TPA• IT configuration file, specifies only

things that TRP messaging service can manage and enforce

• No business information• Derive from BP metamodel

Messaging Services

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?

Do I have to choose between EDI and ebXML?

“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.”

No business communicates No business communicates solely in its supply chainsolely in its supply chainEDI • 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%

How does ebXML fit into web services?

“ebXML, SOAP and XHTML have emerged as technologies likely to provide the foundations for future Web services.”

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

WSDL and ebXML CPP

WSDL provides:

Service nameService parameters Endpoint for

invocation

ebXML CPP provides:

Service nameService parameters Endpoint for

invocationRole of an

organization in the context of a service

Error-handling Failure scenarios

WSDL and ebXML BP

WSDL identifies

Business processes

ebXML BP identifies

Business processes Roles an organization

must playMessages being

exchanged

“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.”

“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.”

NOTE: ebXML offers a way to use UDDI to locate ebXMLregistries http://www.ebxml.org/specs/rrUDDI.pdf

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

An Important Distinction

SOAP, UDDI, WSDL• Developed by a small

group of vendor companies

ebXML• Developed in an open

process by more than

4500 participants representing 2000 organizations in

150 countries on virtually every continent

Who’s implementing ebXML now?

Backed by Vendors

Is ebXML going to replace industry specific vocabularies?

“ebXML provides a platform on which to build standards that are developed faster and yet supported by a rich set of software tools.”

ebXML Adoption Making Headlines

• RosettaNet Adopts ebXML in RNIF• Covisint (GM, Ford, Daimler-Chrysler)

Supports ebXML for Automotive Industry• OpenTravel Alliance Specs Recommend ebXML • Open Applications Group Integrates ebXML into

182 Business Transaction Standards

• Global Commerce Initiative (GCI) Adopts ebXML in Data Exchange Standard for B2B Trade in Consumer Goods

“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.”

Backed by Industry Groups

The Open Healthcare Group

“We've got to pound a stake in the ground and move forward. ebXML is the stake we've chosen.”

Jeff CrippsDirector of Industry RelationsCovisint(eBusiness exchange founded by General Motors, Ford and Daimler-Chrysler)

What’s next?

ebXML Work Continues

• OASIS UN/CEFACT ebXML Coordination Cmte • OASIS UN/CEFACT ebXML Marketing Team• OASIS UN/CEFACT ebXML Tech Architecture• OASIS ebXML Collaboration Protocol Profile TC• OASIS ebXML Implementation/Interoperability TC• OASIS ebXML Messaging Services TC• OASIS ebXML Registry TC• UN/CEFACT e-Business Transition Ad hoc WG

(eBTWG)

What do I need to remember about ebXML?

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.

Get involved in ebXML

• Download the specs from www.ebxml.org• Join OASIS • Subscribe to ebXML-DEV mail list • Review public archives of OASIS ebXML

TC work• Encourage your industry group to adopt

ebXML specifications in standards• Specify ebXML-compliance from

providers

“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.”

“ebXML is our only chance this decade to establish an international e-commerce standard.”
