[Dorset] Cabinet Office Survey on Open Standards in the Public Sector
All, The Government has set up a Public Survey entitled 'Open Standards in the Public Sector', see http://www.surveymonkey.com/s/UKGovOpenStandards. This survey covers quite a wide range and some elements of it are unlikely to be relevant to LUG member's interests. However, it includes all the IT Standards for web, email, etc and also document formats. It takes a bit of dedication to fill it in (there are 120 questions altogether), but whole sections can be skipped if they aren't relevant and it is permissible to leave questions unanswered. I found that I simply didn't know enough about some aspects covered, but I knew enough to answer a fair proportion of the survey. Can I suggest that we make it a LUG Project to visit the Survey and fill it in? Between us we probably know more about these technologies and Standards than most groups(certainly groups outside of software/web development), so we owe it to the Country to deliver some of that expertise on behalf of those ordinary folk who will be saddled with unsuitable Standards if the vested interests get a look-in. Having said that they may already have got a look-in because the questions about document formats in Section 11 state that ISO/IEC 29500:2008 (Office Open XML (or MSXML to the rest of us)) is called Open Office XML, which is easily confused with OpenOffice.org. Maybe it's a genuine mistake or maybe the fix is in. Anyway, like voting, if we don't participate we can't complain about the outcome. -- Terry Coles 64 bit computing with Kubuntu Linux -- Next meeting: Blandford Forum, Wednesday 2011-05-04 20:00 Meets, Mailing list, IRC, LinkedIn, ... http://dorset.lug.org.uk/ How to Report Bugs Effectively: http://goo.gl/4Xue
