SIDEBAR: The Road Gets Less Bumpy

Group Releases Set of Guidelines for Building Interoperable Web Services

Users concerned about being able to build interoperable Web services got an encouraging sign in August when an industry group released a long-awaited set of guidelines that vendors are expected to support in products. The Web Services Interoperability Organisation (WS-I), whose 170 members include vendors and user companies, announced the availability of its Basic Profile 1.0 guidelines, which detail how a set of core Web services specifications should be used to build interoperable Web services.

In developing the Basic Profile, the WS-I addressed about 200 problematic issues related to the specifications and their interoperability, said Steven VanRoekel, director of Web services at Microsoft. The WS-I has also pledged to release test tools that can be used to check if an application is compliant with the Basic Profile. Test tools are due this spring for both the Java and C# development environments.

Sample applications are also scheduled to be made available to provide developers design, implementation, test and deployment scenarios in various business situations on 10 different platforms.

The Basic Profile guidelines are intended for vendors, large corporations and industry consortia developing software and tools that can be used to write Web services, said Jason Bloomberg, an analyst at ZapThink LLC. "A lot of the grey areas with the basic Web services standards are now resolved, and we can move on to the more challenging areas: security, management, reliability and transactions," Bloomberg said.

The WS-I is continuing work on Version 1.1 of the Basic Profile, which will add support for attachments in SOAP-based messages, and on the Basic Security Profile. But it remains unclear what the WS-I's plans are for SOAP 1.2, according to VanRoekel. The new version of SOAP, which the World Wide Web Consortium finalised in June, brings substantial improvements over the 1.1 edition that became the de facto standard among vendors.

Tom Glover, chairman of the WS-I, has said that the group will consider incorporating SOAP 1.2 into a future version of the Basic Profile.
