Congratulations and thanks to Pamela Dingle for publishing a detailed analysis of what that the industry accomplished together during the Third OSIS User-Centric Identity Interop (I3). As Nulli Secundus writes about the paper:
The OSIS I3 Interop was a five-month event in which organizations, individuals, and projects working in the solution spaces of Information Cards and OpenID collaborated to define and demonstrate their ability to transact successfully regardless of differences in hardware or software platform. Participants worked within each solution space to define and test acceptable behaviors for various situations that crop up when loosely coupled solutions communicate with each other via open protocols. Interop participants created results within two different matrices: feature test results which recorded adherence to acceptable behavior when explicitly tested, and cross-solution results which recorded overall interoperability between solutions with complimentary roles. Combined, the participants recorded over 1200 mostly successful results.
As new solutions enter this space and existing solutions add to their feature sets, the OSIS Interop process and results serve as a metric to inform developers what features will contribute to a consistent experience for users and administrators. OSIS Interops have served as a focal point for discussion and feature concentration and a forcing function to solidify the protocols. Overall, much was accomplished but there is still work to be done. By examining participation, contribution to best practices, process and collaboration, discoveries, and obstacles, the Interop process can be refined and improved to give even more value to those involved; by doing so, diversity in product offerings will not result in difficulty for end users.
Many of the learnings and conclusions that Pamela has captured in the paper have informed the Fourth OSIS User-Centric Identity Interop (I4), which is under way and builds on the accomplishments of I3 and the previous interops. Check out the paper and if you have an implementation of Information Card or OpenID software, the time is now to participate in I4!
