[3dem] July 21, 2027: PDB Beta Archive Will Replace Current Archive

[Justin Flatt]

Starting July 21, 2027:

  	* The PDB Beta Archive [1] will replace the current PDB main archive 
[2]. The current beta archive URL will point to the main archive.
  	* PDB entries that have been issued 4-character PDB IDs, including IHM 
structures in PDB-IHM, will be accessed in this archive using their 
extended PDB ID that prepends "pdb_0000" to the 4-character ID (e.g., 
1ABC becomes pdb_00001abc).
  	* OneDep will only issue 12-character IDs (prefix pdb_ followed by 8 
alphanumeric characters, e.g., pdb_1000axyz).

  	* New 4-character PDB IDs will not be issued at this point.
  	* Data deposited after July 21, 2027 will only be released in 
PDBx/mmCIF and PDBML formats.
  	* Legacy PDB formatted files will not be generated for these entries.

The PDB Beta Archive [1] is designed to be scalable and extensible. All 
files in this archive are re-organized using extended PDB IDs (including 
file naming and directories).

All PDB users, including software developers and journal editors, must 
transition to this new archive directory structure, PDBx/mmCIF and 
extended PDB ID format. Start using extended IDs and PDBx/mmCIF data 
files today.

For any further information please contact us at info at wwpdb.org.
