It has been a while since DDWG reported, because the group has been busy dealing with technical comments on the draft API that was published several weeks ago. Comments were managed in public, and mainly they were addressed by providing additional clarity and a few adjustments to the text. Since completing this work, the group has attended a face-to-face meeting in France where several successful implementations were demonstrated. The implementation report
summarises the results, which show that all of the API features are viable.
The successful implementation by several independent contributors will go a long way to progressing this specification towards being a W3C Recommendation. If you are interested in implementing it yourself, check out the latest stable version
There's a pretty picture of the API on the DDWG home page
