October, 2004 Interoperability: Ensuring the Success of Web Services An Overview to WS-I Copyright © 2004 by The Web Services Interoperability Organization (WS-I). All Rights Reserved 1 Agenda Why is Web services interoperability important? The evolution of the Web services “stack” An introduction to WS-I WS-I’s activities: past, present and future How WS-I works with other standards organizations Becoming a WS-I member Copyright © 2004 by The Web Services Interoperability Organization (WS-I).

All Rights Reserved 7 What is WS-I? An open industry effort chartered to promote Web Services interoperability across platforms, applications and programming languages. A standards integrator to help Web services advance in a structured, coherent manner Approximately 130 member organizations 70% vendors, 30% end-user organizations Strong non-U.S. membership, including very influential Japan SIG Copyright © 2004 by The Web Services Interoperability Organization (WS-I). All Rights Reserved 8 WS-I Goals • Achieve Web services interoperability Integrate specifications Promote consistent implementations Provide a visible representation of conformance • Accelerate Web services deployment Offer implementation guidance and best practices Deliver tools and sample applications Provide a implementer’s forum where developers can collaborate • Encourage Web services adoption Build industry consensus to reduce early adopter risks Provide a forum for end users to communicate requirements Raise awareness of customer business requirements Copyright © 2004 by The Web Services Interoperability Organization (WS-I). All Rights Reserved 9 WS-I Value Proposition For end-user companies Reduces the cost, complexity, and risk of adopting Web services Accelerates interoperable products and solutions to market Helps ensure that business requirements are met For vendors Satisfies customer demand for cross-vendor interoperability Speeds time-to-market for new product development Enables vendors to influence industry direction as WS-I members For all developers Increases productivity via specifications, tools and best practices Establishes framework for leveraging expertise of other developers Enables developers to influence industry direction as WS-I members Copyright © 2004 by The Web Services Interoperability Organization (WS-I). All Rights Reserved 10 Deliverables Profiles Defined set of specifications or standards at specific version levels Guidelines and conventions for using these specifications together in ways that ensure interoperability Sample applications Use cases and usage scenarios based on customer requirements Sample code and applications built in multiple environments Demonstrate profile-based interoperability Test tools and supporting materials Tools that test profile implementations for conformance with the profiles Supporting documentation and white papers Copyright © 2004 by The Web Services Interoperability Organization (WS-I). All Rights Reserved 11 Current Working Groups Basic Profile Working Group Core set of specifications that provide the foundation for Web services Basic Security Profile Working Group SOAP messaging security, transport and other security considerations XML Schema Work Plan Working Group Plan appropriate solutions for XML Schema interoperability issues Copyright © 2004 by The Web Services Interoperability Organization (WS-I). All Rights Reserved 12 Current Working Groups Sample Applications Working Group Illustrate best practices for implementations on multiple vendor platforms Testing Tools Working Group Develops self-administered tests to very conformance with WS-I profiles Requirements Gathering Working Group Captures business requirements to drive future profile selection Copyright © 2004 by The Web Services Interoperability Organization (WS-I). All Rights Reserved 13 Delivered to Date Basic Profile Basic Profile 1.0 and 1.1 — More than 200 interoperability issues resolved in the Basic Profile 1.0; conventions around messaging, description and discovery Simple SOAP Binding Profile 1.0 — Derived from Basic Profile requirements related to serialization of an envelope and its representation in the message Sample Applications and Testing Tools for the Basic Profile • Attachments Profile 1.0 Complements the Basic Profile 1.1 to add support for conveying interoperable, SOAP with Attachments (SwA) with SOAP messages Copyright © 2004 by The Web Services Interoperability Organization (WS-I). All Rights Reserved 14 Delivered to Date Basic Security Profile Security Scenarios (Working Group Draft) — Document security risks in interoperable Web services, along with potential countermeasures Basic Security Profile 1.0 (Working Group Draft) — Addresses transport security, SOAP messaging security and other security considerations for WS-I Profiles — Profiles OASIS’ Web Services Security specification — Final version expected in early, 2005 Copyright © 2004 by The Web Services Interoperability Organization (WS-I).
