Snapshots have been archived annually since 2005 to provide readily 
identifiable data sets for research on the PDB archive.

The directory 20250101 includes the 229,564 experimentally-determined 
structure and experimental data available at that time. Atomic 
coordinate and related metadata are available in PDBx/mmCIF, PDB, and 
XML file formats. The date and time stamp of each file indicates the 
last time the file was modified. The snapshot of PDB Core Archive is 
1,437 GB.
