Dictionary Definition Language DDLm
The methods Dictionary Definition Language (DDL) is a
proposed formalism for the recording of CIF data names and
their definitions and properties within CIF dictionaries, with
descriptions of algorithmic methods for evaluation and validation.
While providing important new functionality to dictionary
and applications software developers, DDLm fully supports
the definition capabilities of the existing dictionary
languages, DDL1 and DDL2, but will provide a higher level of
semantic content for domain dictionaries. No changes are
required in existing archival data files in order to apply
domain dictionaries written in DDLm.
Note that the example dictionaries distributed with this
draft (cif.dic, cif_core.dic, core_*.dic) are not
intended as a proposed implementation of the core dictionary
in DDLm, but are just mockups used to trial the DDLm
attributes and indicate possible areas of development.
See also the basic DDL1
and relational DDL2
dictionary definition languages.
