I would suggest actually writing the utility you have in mind. In practice, inasmuch as a CIF file looks like a text file, people are very likely to just pick one up in any convenient text editor change what they want to change and write an unidentified pseudo-cif file back out. Anything else needs to be provided to them in a complete, platform portable, well-documented package they can use easily in place of an editor that they use all the time for everything else. Please be practical -- CIF is a working tool, embedded in the IUCr journal process flows, in many crystallographic applications, in the PDB workflows, in Dectris detector software, etc.,. etc. The more disruptive you make the transition from CIF1 to CIF2, the more software and documentation you need to create to allow people to make the transition actually happen. We are essentially in the same place we were in Osaka. How do we break out of this loop and move forward? We need a realistic plan to get our job done and have a complete specification with the necessary supporting software for CIF2 in place and ready to demonstrate for Madrid, or I would suggest we accept the failure of this effort, and start over. -- Herbert At 10:32 PM +1000 9/13/10, James Hester wrote: >The original concept was to edit the non UTF8 files in the text editor >of choice, then run a simple checksumming application (that >understands CIF2 syntax) to update the checksum.
