PDBML Schema Resources

The Protein Data Bank Markup Language (PDBML) provides a representation of PDB data in XML format. The description of this format is provided in XML schema of the PDB Exchange Data Dictionary. This schema is produced by direct translation of the PDBx/mmCIF Exchange Data Dictionary Other data dictionaries used by the PDB have been electronically translated into XML/XSD schemas and these are also presented in the list below.

• Data files in PDBML format can be downloaded from the wwPDB ftp site.
• PDBML data files are provided in three forms:
  • fully marked-up files,
  • files without atom records
  • files with a more space efficient encoding of atom records
• An article describing PDBML is available.
