The PDB Beta Archive
https://www.wwpdb.org/news/news.php?year=2026#69ebcdca1103c56d3f444159
will replace the current archive July 21, 2027. The PDB Beta Archive
organization supports the transition to extended PDB IDs. Users are
strongly encouraged to start using this new directory structure and
extended PDB IDs now.
“Shortlinks” https://www.wwpdb.org/ftp/pdb-beta-ftp-sites#dataStCon
are URLs that can be used for downloading data from the beta archive
today without the need to know or code specific file paths, e.g.,
https://files-beta.wwpdb.org/download/pdb_00001abc.cif.gz
When the PDB Beta Archive becomes the main PDB Archive, shortlink users
will only need to update the domain name for these shortlinks:
https://files.wwpdb.org/download/pdb_00001abc.cif.gz
wwPDB recommends that users with automated workflows adopt shortlinks today.
Example Shortlinks
https://files-beta.wwpdb.org/download/pdb_00001abc-sf.cif.gz
https://files-beta.wwpdb.org/download/pdb_00001abc_nmr-data.str.gz
