Dear Tom,
This has crossed my mind as well. Although I wasn't aware about standardization organizations offering these standards free of cost. In the Netherlands one related aspect has been taken to court, namely that some of the laws refer to standards which aren't available freely or free of cost. It was ruled that this was not particular issue, as the cost was justifiable for setting and maintaining the standards, and the standard was available in a non-discriminatory fashion (if I remember correctly).
The collection of standardization bodies are quite complex, with national organizations, industry-specific organizations, and international organizations (ISO, EN, IEC), often approving each other's standards. Coming from a power systems background, standards defining electromechanical systems like fuses, power cables and circuit breakers is very industry-specific and is mainly of interest to manufacturers and system engineers, which then again are mostly larger organizations. Somewhat remarkable my university has stopped adopting standards because the little use in academics didn't justify the cost of the license.
The main difference with software standards, and web-standards in particular seems to be that even individuals have the ability to create a working product, as no industrial manufacturing process is required. Adhering to closed, costly standards would be much more significant, unless maybe a reference implementation (library) would be available for use, removing the need for the actual standard to be read. So the cost of common software standards is therefore required to be approaching zero.
Scott's writing on standard adoption explain the way in which project can adopt standards and the many issues related to bringing about open standards.
I was reluctant to read an article by Gijs Hillenius in the Dutch Linux Magazine regarding the updated Open Source strategy of the European Commission, in which he pointed out that the EC was explicitly considering open standards in favor of other established standards. I consider this to be the confirmation that not-open standards are non preferable in relation to free software.
As society seems to become more decentralized and dynamic, the conventional standardization model will be under ever more pressure to lower the barriers of access, regarding cost, license of use, and transparency of process.
Thanks for bringing up this interesting topic. I'm very interested to hear the viewpoints and findings of others on this as well.
Kind regards, Nico Rikken
