Slide1: 

Interoperability: Ensuring the Success of Web Services October, 2004 An Overview to WS-I

Slide2: 

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 Agenda

The Web Services Context

Slide7: 

The Web Services Standards Stack Composition/Orchestration Business Process Orchestration Portals Management XML, SOAP XML Schema, WSDL, UDDI, SOAP with Attachments HTTP, HTTPS,Others Invocation Description Transports Composable Service Elements Transactionality WS-Security Reliable Messaging Endpoint Identification, Publish/Subscribe Messaging Additional Capabilities

Slide8: 

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 What is WS-I?

Slide9: 

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 WS-I Goals

Slide10: 

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 WS-I Value Proposition

Slide11: 

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 Deliverables

Slide12: 

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 Current Working Groups

Slide13: 

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 Current Working Groups

Slide14: 

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 Delivered to Date

Slide15: 

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 Delivered to Date

Slide16: 

The Web Services Standards Stack Composition/Orchestration Business Process Orchestration Portals Management XML, SOAP XML Schema, WSDL, UDDI, SOAP with Attachments HTTP, HTTPS,Others Invocation Description Transports Composable Service Elements Transactionality WS-Security Reliable Messaging Endpoint Identification, Publish/Subscribe Messaging Additional Capabilities

Slide17: 

WS-I’s Work to Date Composition/Orchestration Business Process Orchestration Portals Management XML, SOAP XML Schema, WSDL, UDDI, SOAP with Attachments HTTP, HTTPS, Others Invocation Description Transports Composable Service Elements Transactionality WS-Security Reliable Messaging Endpoint Identification, Publish/Subscribe Messaging Additional Capabilities

Slide18: 

Ongoing work Basic Security Profile Requirements gathering XML Schema Work Plan Likely future candidates Update Basic Profile to include SOAP v1.2, WSDL v2.0, UDDI v3.0 Other profile candidates include reliable messaging, transactionality, orchestration, etc. Driven by market demand What’s Next

Slide19: 

WS-I, Standards, and Industry

Slide20: 

Reduce cost, complexity and risk Provides confidence in interoperability Common implementation guidelines Improve productivity and accelerate time to market Eases collaboration, both internally and with business partners Allows companies to focus on added value, not basic plumbing Simplify Web services buying decisions The WS-I logo identifies conformance Business Value of WS-I Conformance

Slide21: 

Join Join a community of 130 industry leaders and visionaries with a shared vision for Web services interoperability Foster commitment across your industry Participate Encourage customer participation and buy-in Commit to an aggressive schedule for delivering resources to aid Web services implementations Adopt Ensure implementations conform with WS-I profiles Promote conformance to customers and partners Join WS-I Today
