Copyright OASIS, 2002 Role of Standards

Copyright OASIS, 2002 Industry Group’s Role in Standards Major user Purchasing power Major developer Domain Expertise Major driver Authority to strongly influence standards development

Copyright OASIS, 2002 To Drive Standards Effectively, Industry Groups Need to... 1.Define Business Requirements 2.Interface with Voluntary Standards Development Organizations (VSDO) 3. Endorse standards developed through open process with market adoption

Copyright OASIS, 2002 ebXML The Global Standard for Electronic Business

Copyright OASIS, 2002 ebXML Provides a Standard Way to: Exchange business messages Conduct trading relationships Communicate data in common terms Define and register business processes

Copyright OASIS, 2002 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

Copyright OASIS, 2002 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

Copyright OASIS, 2002 Main ebXML concepts Business Processes – Defined as models, Expressed in XML Business Messages – Expressed in XML Trading Partner Agreement – Specifies parameters for businesses to interface with each other – Expressed in XML Business Service Interface – Implements Trading Partner Agreement – Expressed in XML Transport and Routing Layer – Moves the actual XML data between trading partners Registry/Repository - Provides a “container” for process models, vocabularies, and partner profiles.

Copyright OASIS, 2002 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 200 member companies plus individuals

Copyright OASIS, 2002 “ebXML is our only chance this decade to establish an international e-commerce standard.”

Copyright OASIS, 2002 “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, 2002 “It is clear that ebXML will soon become the standard for all global trade. By implementing ebXML, GCI takes advantage of the excellent work that’s being accomplished to streamline many EDI processes and remove waste and redundancy from supply chains.”

Copyright OASIS, 2002 E-Business Web Services ebWS

Copyright OASIS, 2002 What is a Web Service? Application to application requests and responses over the web stack – SSL – HTTP/SMTP/... – XML – SOAP – ebXML/UDDI Registry RPC and Business Messaging all loosely coupled...

Copyright OASIS, 2002 Types of Web Services Simple – No side effects – Non-transactional – Context free – Sessionless, no roles – Minimal security – Call-response model – Point-to-point – Not developmentally scalable Complex, e-Business – Impacts other steps – Transactional – Context sensitive conversions, ordering of steps – Session based, personalized – Exactly once semantics – Sophisticated security – Messaging based – Scalable

Copyright OASIS, 2002 Remote Procedure Call (RPC)- based Web Services Implemented using a stateless session EJB. Appears as a remote object to the client application. The interaction centers around a service- specific interface. Tightly coupled and resemble traditional distributed object paradigms, such as RMI or DCOM. Synchronous, meaning that when a client sends a request, it waits for a response before doing anything else.

Copyright OASIS, 2002 Protocols for RPC-based Web Services Simple Object Access Protocol (SOAP) – W3C XML Protocol WG – SOAP v1.2 – Still in process Web Services Description Language (WSDL) – WSDL v1.1 (IBM & MS) W3C Note Mar – W3C WS Description WG started Jan Universal Description, Discovery and Integration (UDDI) – UDDI.org v2.0 specification June 2001

Copyright OASIS, 2002 Conversational or Message-Based Web Services Loosely coupled and document-driven Client invokes a message-based Web Service by sending it an entire document, such as a purchase order, rather than a discrete set of parameters. The Web Service accepts the entire document, processes it, and may or may not return a result message. Promotes a looser coupling between client and server and provide additional benefits beyond RPC-based Web Services

Copyright OASIS, 2002 How does this relate to ebXML? Exchanges, e-markets, supply chains, etc. need combinations of web services – Auction, pricing, tax computation, customs, RFP, RFQ, order management, content management – No two exchanges will use the same combination of services and service packages – Custom combinations require a framework approach ebXML provides the framework and many pieces
