I've also been following the discussion on the future of robot description formats in both ROS 1 and 2 here and in the various other linked channels, again, on and off, and I feel most people have been doing the same, with the last "wave of interest" rising and subsiding last fall. So as far as I can see, it is still an unsolved topic, and thus I was thinking of incorporating it in my proposed talk, trying to to provide a summary of the relevant points raised in discussion so far and compiling a list of the mentioned requirements and possible ways to go forward.
My hope is obviously that this would bring this topic back on people's minds, we could maybe get together for a birds-of-a-feather-meeting afterwards and thus possibly finally start a community effort to really go forward with this.
So my question: Would you like to see such a talk and would you be interested in organizing a birds-of-a-feather or even more 'formal' meeting on the topic at ROSCon 2017? And if so, which specific points would you like to see raised?
