WS Protocol Workshop Process Jorgen Thelin, Microsoft Corporation The path to interoperable Web Services specifications

Workshops – The Path to Interoperable Specs Purpose:  Applying software testing practices to Web Services specs  Provide review, testing and validation of WS-* specifications earlier in the spec development cycle Goal: INTEROPERABLE SPECS  Find and fix problems in the specs before they are widely implemented and adopted  Gather feedback from implementers, vendors and other interested parties on spec interoperability and usability problems  Demonstrate and test of the interoperability achievable using the spec(s) Result:  Community consultation and involvement in the spec development process  Proven interoperability among spec implementations

Workshops - Attendance Open to EVERYONE  Anyone who signs a feedback agreement can: Attend feedback or interop workshop Post to workshop mailing lists For example  Spec authors  Companies with known interest in the spec  Authors of competing specs, if they wish  Researchers / University staff

Types of Workshop Feedback Workshop  Gather comments from implementers and interested parties  Equivalent to: Code review / walkthrough Interop Workshop  Exercise spec implementations  Equivalent to: System / integration testing for software

Feedback Workshop Details Audience: all interested parties  Just sign the feedback agreement Goal: Gathering feedback on published drafts Format - 1-day event  Presentations for half a day  Feedback discussion for half a day Deliverables  Feedback to spec authors  Suggestions for future interop scenarios

Interop Workshop Details Audience: spec implementers  Sign the feedback agreement and bring your own implementation Goal: Achieving interoperability between implementations Format - 2-day event  Round-table interoperability lab - 1 room, many implementations  Hands-on peer-to-peer testing - BYO Laptop  Test cases created in advance – included in invite pack Deliverables  Feedback to spec authors on implementability of spec(s)  Broad levels of interoperability between implementations  Suggestions for future interop scenarios  (If possible) Live endpoints from ongoing testing

Why the incremental approach? Rome wasn’t built in a day  Neither was the Internet, or any major IT infrastructure! Specs take time to settle in and usage experiences develop Building the higher layers of the architecture can point out changes required in lower levels For example: HTML didn’t jump straight to v4.0 – it took time to see what worked and what didn’t
