What is a Web Service?

Profile Specifications


W3C Web Service Architecture Group - Definition of Web Service

A Web service is a software application

identified by a URI, whose interfaces

and bindings are capable of being

defined, described and discovered as

XML artifacts. A Web service supports

direct interactions with other software

agents using XML based messages via

internet-based protocols.

W3C – WSAG (draft): Basic Web Service Architecture

© W3C 2002.


W3C – WSAG (draft): Extended Web Services Architecture

© W3C 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,

ordering of steps– Session based,

personalized– Exactly once semantics– Sophisticated security– Messaging based– Scalable


Two Types of Web Services

• Remote Procedure Call (RPC)-based for supporting simple Web Services

• Conversational or Message-based Web Services for supporting loosely coupled asynchronous models, a key requirement for Enterprise-class Web Services.


Protocols for RPC-based Web Services• Simple Object Access Protocol (SOAP)

– SOAP v1.1 (IBM, MS, etc.) W3C Note - May 2000 – W3C XML Protocol WG started - Sep. 2000– SOAP v1.2 Working Draft - June 2002

• Web Services Description Language (WSDL)– WSDL v1.1 (IBM & MS) W3C Note - Mar. 2001– W3C WS Description WG started - Jan. 2002– WSDL v1.2 Working Draft - July 2002

• Universal Description, Discovery and Integration (UDDI)– UDDI.org v3.0 specification - July 2002– OASIS UDDI Spec. TC approved v2, v3 - Sep. 2002


Protocols for Message-Based Web Services• ebXML Messaging Services

– ebXML Messaging v2.0 TC Spec. – Mar. 2002– ebMsg. v2.0 OASIS Standard – Sep. 2002

• ebXML Collaboration-Protocol Profile– CPP/A v2.0 TC Specification – May 2002– CPP/A v2.0 submit for OASIS Standard – July 2002

• ebXML Registry – ebXML RIM v2.0 OASIS Standard – Apr. 2002– ebXML RS v2.0 OASIS Standard – Apr. 2002

• Business Transaction Protocol– BTP v1.0 TC Specification – May 2002


Web Services

• Step 1: Description – WSDL – ebXML CPP & ebXML Business Process Schema

• Step 2: Publication and Discovery– UDDI– ebXML Registry

• Step 3: Invocation – SOAP over HTTP– ebXML Messaging Spec integrating SOAP, HTTP

ebXML

The Global Standard for Electronic Business, and eBusiness Web Services


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


ebXML Provides a Standard Way to:

• Exchange business messages• Conduct trading relationships• Communicate data in common terms • Define and register business

processes


• 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


ebXML History

• Begun as 18-month initiative in November 1999

• V1.0 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


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


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.


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


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

Future directions

• Connection to Business server model and generic ebXML service support for persistent objects and language service

• Acceptance by clients


Continuing ebXML Work

• Specifications completed May 2001; available at www.ebxml.org

• Infrastructure work continuing at OASIS– Messaging– Collaborative Partner– Interoperability, Implementation, Conformance– Registry & Repository

• Content-related work continuing at UN/CEFACT– Business Process– Core Components


How do ebXML & web services fit into your corporate strategy?
