Formal specification (BNF) for CIF

  • Subject: Formal specification (BNF) for CIF
  • From: Brian McMahon <bm@xxxxxxxx>
  • Date: Sat, 30 Sep 2000 18:58:51 +0100 (BST)
Following earlier discussion on the cif-developers and comcifs-l
discussion lists, a draft Backus-Naur Form specifying the syntax and
grammar of CIF has been posted for public review at
The period of review will end on October 31 2000. If no objections are
forthcoming, this will be accepted as the definitive BNF for CIF,
to ensure greater consistency in the behaviour of CIF software.

Comments on the draft should be submitted to the COMCIFS coordinating
secretary (bm@iucr.org) or the author of the BNF (nick@cs.uwa.edu.au)
before the October 31 deadline. Public discussion is also invited
on the cif-developers@iucr.org distribution list.
