[ccp4bb] OT: mapping PDB to mmCIF data quantities

[Phil Jeffrey]

I'm updating some code to have limited mmCIF/PDB format interoperability 
and have hit a snag.  While I can infer the connection between some data 
items in the PDB header REMARK and the items in mmCIF I can't 
definitively deduce some others.  In particular the mapping of
REMARK  2  RESOLUTION
seems a little ambiguous and the dictionary documentation doesn't help 
in this regard.

Does anyone know where to find an explicit mapping of one data field to 
another between the two formats ?  (I don't expect there to be a data 
field in the PDB header for everything in mmCIF but I do for the reverse 
case).


Thanks
