[Imgcif-l] CBF file templates

[Chris Nielsen]

      Hi All,
 
      I tend to agree that a complete filling-in of the nominal template is probably
not going happen in many places, at least to start, but I would suggest that if
the DLS beamlines do a good job of it and the "extra" (beyond essential data processing
header items) turn out to be useful for this or that, more beam lines will do a more
complete job.  I'd note that these items should be sort of "backward compatible" in
the sense that, to start with, if you only fill in a few "extra" items it should not matter
that a future header has more complete information.  It's hard to see the downside in this.
 
      Graeme:  What are your thoughts on the coding required to do this?  Have you made
an attempt yet?
 
      Chris

I support templating, but compliance is likely to be an issue. When Jim
Pflugrath deliberately put in-your-face comments into the D*Trek
"comments" header slots that were designed to force beamlines to customize
their local implementations, seveal of the beamlines that used D*Trek
ignored those comments. So a lot of D*Trek-aquired data have comments
fields that contain language like "This is a meaningless header that
should be replaced by something with content".
