Jon Udell, et al. wonder about the value of open source and/or standards.
I would hesitate to adopt any standard that does not already have a up-to-date open source implementation. And I would refuse to define a standard without concurrently defining an open source implementation.
I've been involved in two standards definition processes. Neither had any significant implementation or formal model to guide them. I suspect other standardization efforts have suffered similar consequences.
Mistakes were made.
