HOW IS THE PDB ARCHIVE MANAGED?
The wwPDB members agree that the RCSB will be the ‘archive keeper’ and will have sole write access to the PDB archive and control over the directory structure and contents. The archive keeper distributes new PDB identifiers to all deposition sites. The members of the wwPDB will undertake to use PDB 4-letter codes as set out in the agreement. The four-letter PDB identifier currently consists of a number (0-9) followed by 3 letters or numbers.
