Standards BodiesThe Organization for the Advancement of Structured Information Standards (OASIS) is a not-for-profit, international consortium

that drives the development, convergence, and adoption of e-business standards. Theconsortium produces more Web services standards than any other organization along with stan-dards for security, e-business, and standardization efforts in the public sector and for applica-tion-specific markets. Founded in 1993, OASIS has more than 4,000 participants representingover 600 organizations and individual members in 100 countries.

The World Wide Web Consortium (W3C) was created in October 1994 to lead the World Wide Web to its full potential by developing common protocols that promoteits evolution and ensure its interoperability. W3C has over 350 Member organiza-

tions from all over the world and has earned international recognition for its contributions to thegrowth of the Web. W3C is designing the infrastructure, and defining the architecture and the coretechnologies for Web services. In September 2000, W3C started the XML Protocol Activity to addressthe need for an XML-based protocol for application-to-application messaging. In January 2002, theWeb Services Activity was launched, subsuming the XML Protocol Activity and extending its scope.

The Web Services Interoperability Organization (WS-I) is an open industry organization chartered to promote Web services interoperability across platforms,

operating systems and programming languages. The organization’s diverse community of Webservices leaders helps customers to develop interoperable Web services by providing guidance,recommended practices and supporting resources. Specifically, WS-I creates, promotes andsupports generic protocols for the interoperable exchange of messages between Web services.

The Internet Engineering Task Force (IETF) is a large open international community of network designers, operators, vendors, and researchers concerned with the evolution of the Internet architecture and the smooth operation of the Internet.
