( From International Organization for Standardization ) :
– “Standards are documented agreements containing technical
specifications or other precise criteria to be used consistently as
rules, guidelines, or definitions of characteristics, to ensure that
materials, products, processes and services are fit for their
purpose.”
– International Standards thus contribute to making life simpler,
and to increasing the reliability and effectiveness of the goods
and services we use

What is e-business ?
 What is an Electronic Commerce (EC) ?
– the process of buying, selling, or exchanging products, services, and

Three Major Standard Bodies on WS
 W3C(World Wide Web Consortium)
– Architecture Domain/Web Services Activity
• 4 working groups
– XML related Activities, working groups.
 OASIS
– Global consortium that drives the development, convergence
and adoption of e-business standards
– ebXML, UDDI, UBL TC, …
 WS-I (Web Services Interoperability)
12
W3C
 “To develop a set of technologies in order to bring Web services to
their full potential.”
 A part of W3C’s Architecture Domain
 Created in January 2002.
 Composed of 5 groups and a Coordination group
–

–
XML Protocol WG
Web Services Description WG
Web Services Choreography WG
Web Services Architecture WG
Semantic Web Services Interest Group
 Duration of WS Activity is Until January 2006
 Outside the Web Services Activity:
– Internationalization task force
– XML Key Management work
– Privacy work in Privacy Activity
