The wwPDB provides depositors with detailed reports (PDF and XML files) that include the results of model and experimental data validation, as part of the curation of X-ray, NMR, and 3DEM entries (announcement).
As these wwPDB validation reports provide an assessment of structure
quality using widely accepted standards and criteria, the wwPDB
partners strongly encourage journal editors and referees to request
them from authors as part of the manuscript submission and review
process. The reports are date-stamped and display the logo of the wwPDB
site where the entry was curated. They contain the same information,
regardless of which wwPDB site processed the entry. Provision of wwPDB
validation reports is already required by Nature, eLife,
The Journal of Biological Chemistry, the International Union of
Crystallography (IUCr) journals, FEBS, J Immunology, and Angew
Chem Int Ed Engl as part of their manuscript-submission process.
The validation reports continue to be developed and improved as we receive
recommendations from the expert Validation Task Forces (VTF) for
EM, as we develop the
wwPDB OneDep system,
and as we collect feedback from depositors and users.
The validation reports for all X-ray, NMR, and 3DEM structures deposited in the PDB archive has been updated in March 2016 with 2015 statistics (announcement).

Sample validation report PDFs for:
a 1.8Å resolution X-ray structure of a small protein and a ligand, an entry with
better overall quality relative to all X-ray structures.
a 3.2Å resolution structure with worse overall quality relative to all X-ray
a 3.6Å resolution structure with possible ligand geometry and fit to density issues.
Validation information and reports for released PDB entries are available from the entry pages at
RCSB PDB and
FTP access to validation reports, in PDF and XML format, for all released X-ray, NMR, and 3DEM entries from
Validation XML Schema:
Information on Stand-alone wwPDB validation servers
that allow experimental structural biologists to produce reports and validate their models
prior to publication and deposition.
