Dear COMCIFS,

As per the resolution at the Montreal COMCIFS meeting, the canonical version of dictionaries that had been written in DDL1, and of any new dictionaries, will be DDLm. The foundation stone of the framework is the core CIF dictionary, a DDLm version of which is currently under review in the core CIF DMG before being presented to COMCIFS for approval. Meanwhile, the magnetic structures commission has produced a magnetic dictionary (in DDLm) which is waiting on core CIF approval before being presented to COMCIFS.  It is hoped that this dictionary, which has the support of the authors of popular magnetic structure software suites, will be formally introduced to the magnetism community at a magnetism workshop in December.  As this is a rare opportunity for the magnetism community to effectively promote magCIF, it is important that COMCIFS expedite its consideration of both core CIF and magCIF.

I therefore propose that our usual leisurely 6 week approval period is reduced to three weeks for the remainder of this calendar year, in view both of the need for timely consideration and the end of the summer holidays in the northern hemisphere. Note that three weeks is simply the period after which the absence of comment following significant changes is taken to be approval, and does not limit discussions started in that period.  Affirmative agreement to this proposal is requested as soon as possible from the COMCIFS voting members (J Westbrook, H Bernstein, J Bollinger, B McMahon).

Assuming that we work within a 3-week timetable, and that no significant issues are identified, our approval timetable looks like the following:

19th Sept: core CIF presented to COMCIFS
10th Oct: core CIF approved by COMCIFS, magCIF presented to COMCIFS
31st Oct: magCIF approved.

This leaves one month of leeway in case any significant problems are identified.

Those of you who wish to get a head start on the two dictionaries mentioned above may view advanced draft versions at the following links:


James.
