Guest guest Posted December 4, 2006 Report Share Posted December 4, 2006 , I assume that the arrangement for letting you printing IESO standard (1st edition) at the end of your book is "no string attached".

Guest guest Posted December 4, 2006 Report Share Posted December 4, 2006 Please forgive me if this seems off topic, but I actually don't think it is..There are some interesting parallels between this debate and the debate in the Internet engineering community about the use and promotion of open standards and interoperability for document and IP protocols. Maybe some of you might be able to gain some insights into the solving of your industry's problems from reading about the issues encountered elsewhere via-a-vis open standards versus standards that use proprietary software, patents, hardware, information or whatever.. Places to look as far as seeing some of these debates are many, but what comes to my mind are the IETF.org site, the CreativeCommons.org and ScienceCommons.org, eff.org, gnu.org, etc. sites.. and others like them.. Searches on the above phrases might also bring up some useful stuff.. This isn't about IAQ, its about the various kinds of information sharing models out there and the relative merits of them all in different situations.. Again, if this seems off topic, please try to see it in a greater context.. This kind of debate is happening in all different kinds of disciplines and industries and I would think that your industry is no exception..
