Dear Colleagues,
Unless we are assuming that the CIF2 transition is not acutally
going to happen, that transition is going to involve a wide range
of both software developers and users of crystallographic software
throughout the community. Either we have te dicsussion with them
on a UTF-8-ony standard now, or we will have to have the discussion
with them later, when it is much harder and more expensive to
revise what we will have done.
If James is reluctant to post his own summary to the lists, then
how about the following:
COMCIFS, the IUCr Committee of the Maintenance of the CIF standard
is considering some important improvements and extensions to CIF.
Among the extensions being considered is enlarging the character
set allowed from simple ASCII to the full UNICODE character set
(the same set of characters used in web browsers with HTML and in XML). There is strong disagreement on COMCIFS as to whether
this would best be done by mandating just a single UNICODE encoding,
UTF-8, or whether is would be best to follow the practives of HTML
and XML in allowing alternate encodings. The full thread of the
discussion thus far can be seen at:
http://www.iucr.org/__data/iucr/lists/ddlm-group/
Comments from interested members of the community would be
appreciated.
Regards,
Herbert

I agree this would probably be more productive.1. Do you regularly use non-ASCII characters when editing text? Examples
Perhaps the IUCr could point its authors at such a survey - via its CIF
author services pages (printCIF, checkCIF...)?
Cheers

Subject: [ddlm-group] Community consulation regarding CIF2 encoding
Dear DDLm-ers,
I think Herbert's suggestion of sending a version of my summary out is
unlikely to produce a great deal of enlightenment, because I expect the
range of responses to simply mirror that which we have already seen in this
group, with no ultimate resolution. I would like to propose instead a
simple questionnaire that we can use to inform our decision. The questions
I would like to see answered are:2. What languages do you usually deal with when editing text?
of such characters include accented ASCII characters, and the characters
from Arabic, Japanese, Chinese, Cyrillic etc. (Yes/No/Don't know)
3. What text editing programs do you usually use?
4. Can the text editors that you usually use read and write files in UTF-85. Which non-ASCII encoding do you think would result in the least problems
format? (yes/no/don't know)6. Would you object to a new CIF standard which allowed only UTF-8 encoded
when transferring your text files across the internet?
files? If so, why?
7. Do you have any comments regarding suitable choice of encoding(s) for
the new CIF standard?
Once we have fine-tuned the questions, I would suggest creating the survey
using www.surveymonkey.com, then posting requests for responses wherever
crystallographers are to be found, but especially in groups where non ASCII
scripts are likely to be found (European Crystallographic Society, Japanese
Crystallographic Society, Computing Commission etc.).
James.
