168493: XML and Web Services (II/2546) 2 Outline What is and Why ebXML? Technical architecture Business process CPP and CPA Registry/Repository Messaging Service Core components ebXML adoption

168493: XML and Web Services (II/2546) 3 Objectives Understanding the fundamental concepts and motivations of ebXML effort as a framework for electronic market place Understanding the architecture of ebXML and its functional modules Being able to interpret and construct ebXML messages Understand the relationship of ebXML to other web services standards

168493: XML and Web Services (II/2546) 4 ebXML Vision A global electronic market place where enterprises of any size, anywhere can: Find each other electronically Conduct business through exchange of XML based business messages ebXML effort was started and sponsored by United Nations (UN/CEFACT, Organization for Advancement of Structured Information Standards) and Organization for Structured Information Standards (OASIS)

168493: XML and Web Services (II/2546) 5 Why ebXML? Need for standardizing business collaboration which in turn enable automation of business collaboration Under ebXML, the actual business transaction occurs by exchanging XML- based business messages The structure of these business messages and the environment of business collaboration need to be standardized

168493: XML and Web Services (II/2546) 6 Why ebXML? SOAP, WSDL, UDDI alone are not adequate WSDL does not address business collaboration SOAP does not provide secure and reliable message delivery UDDI does not provide repository

168493: XML and Web Services (II/2546) 7 Why ebXML? Existing B2B Framework are not adequate EDI Too heavy-weight and too rigid Has been used only by large companies RosettaNet Does not provide machine-readable business collaboration documents BizTalk Proprietary Single-vendor Single-platform

168493: XML and Web Services (II/2546) 8 Goals of ebXML Make electronic business simple, easy, and ubiquitous Use XML to the fullest extent possible Offer an open standard that enables business transactions across industry boundaries for both business-to-business and business-to-consumer commerce

168493: XML and Web Services (II/2546) 9 Goals of ebXML Bring together the structure and content of various XML business vocabularies into a single specification Offer a migration path from current EDI standards, as well as XML vocabularies Keep adoption costs to a minimum

168493: XML and Web Services (II/2546) 10 ebXML Use Case Scenario Step 1. Company A checks ebXML registry to see what kinds of business processes are already defined Step 2. After company A finds the business it wants, for example, “purchase order” business process, it decides to build and deploy its own application that captures the semantics of that business process

168493: XML and Web Services (II/2546) 11 ebXML Use Case Scenario Step 3, company A then submits its own business profile to ebXML registry. The business profile describes the business processes the company support as well as its ebXML capabilities and constraints For example, it might want to register its business profile which says that it can participate in purchase order business process as a buyer

168493: XML and Web Services (II/2546) 12 ebXML Use Case Scenario Step 4, company B discovers business processes supported by company A in the ebXML registry by looking at business profile submitted by company A Step 5, company B sends a request to company A indicating its interest in engaging business transaction Step 6, company A accepts the business arrangement and finally business transaction occurs between the two

168493: XML and Web Services (II/2546) 14 ebXML High-level Architecture Messaging Service Business Process Specifications Specification Registration and Discovery Models And Profiles Partner Profiles And Agreements

168493: XML and Web Services (II/2546) 15 ebXML Value Addition Business process, CPP/CPA over WSDL Defines business process collaboration ebXML Reg/Rep over UDDI Repository as well as registry ebXML message service over SOAP Reliability and security semantics Core components
