The archival PDB files will be distributed with the reserved
conventional names, in the form pdbentry_id.ent, where
entry_id is a PDB 4-letter code, e.g. pdb1abc.ent, for PDB
format entries; rentry_idsf.ent, e.g. r1abcsf.ent, for X-ray
experimental data; entry_id.mr, e.g. 1abc.mr, for NMR
experimental/constraints; entry_id.cif, e.g. 1abc.cif, for
mmCIF format entries; and entry_id.xml, e.g. 1abc.xml, for
canonical XML format entries.
By providing a formal mechanism for standardizing the
presentation of PDB data, software developers and users of
the data will be assured of consistent data. At the same time, it
is hoped that this agreement will allow for individual creativity
in how the data are presented and made available to the
