This is a reply to the below message posted under "[ccp4bb] The
importance of USING our validation tool", which is a rather long thread now.

This is part of why I claim that wwPDB and its members are doing a bad
job. They have worked to systematically remove "general purpose"
information that does not fit their pre-defined schemes, which are
developed with out much interaction with the user community. the problem
is that we are doing RESEARCH, which means that we will continue to
develop new methods over time. The sensible thing to do is to allow
unformatted user-defined information, and eventually work it in to a
properly formatted, standard item if that information is seen as
generally useful by the user community.

I think that the lack of community involvement by the database
administrations should be a clear indication of why we should NOT switch
from PDB to mmCIF format for coordinate files. Instead, we should take
this opportunity of wwPDB members abandoning the PDB format to take over
management of the format ourselves. I was quite irate with them for
going against our wishes on several features of the PDB format, like
supporting the SegID. Instead, I think we should realize that "modern
database" management goals are different from experimentalist goals, and
that we should not rely on them to decide how our own data should be
represented.

I think that we should intentionally avoid mmCIF for coordinate files,
and stick to the PDB format. The wwPDB has absolutely no policy for user
involvement, and RCSB has clearly dropped the previously establish
PDB-format change policy. Their task was never to manage a public file
format standard. This is an opportunity to turn the PDB file format into
a public standard.

I have started a PDB Format Wiki, running on my home computer, at
http://pdb.homeunix.org. If it gains interest, I will see about moving
it to a proper Internet host.
