The schema file to define PDBML data description rule is available from following URL:
The file name of a PDBML file is pdbid.xml. For example, 1a00.xml, 1gof.xml, etc.
These files are also called ``all'' files since it contains all data.
There are variants of PDBML files called ``noatom and ``extatom files which are described in the following pages:
- PDBML-noatom In short, ``noatom'' files are PDBML files without the atom_site category (i.e., no atomic coordinates).
- PDBML-extatom In short, ``extatom files contain only atomic coordinates and related information, but in a more concise format than the atom_site element of PDBML. This is similar to the ``ATOM lines of the classical PDB format (but not exactly the same).
