Dictionary Definition Language (DDL) is a STAR-based file format, which allows user communities to define their own custom STAR-based file format for the data they need to exchange. DDL plays a similar role for STAR as XSD does for XML.

Examples

http://www.iucr.org/resources/cif/dictionaries - IUCr page listing DDL dictionaries for the CIF file format http://mmcif.wwpdb.org/dictionaries/mmcif_pdbx_v40.dic/Index/ - DDL dictionary for the mmCIF file format - including a web interface to browse the structure of the file.
