"""

A collection of container classes supporting the PDBx/mmCIF storage model.

A base container class is defined which supports common features of
data and definition containers.   PDBx data files are organized in
sections called data blocks which are mapped to data containers.
PDBx dictionaries contain definition sections and data sections
which are mapped to definition and data containers respectively.

Data in both PDBx data files and dictionaries are organized in
data categories. In the PDBx syntax individual items or data
identified by labels of the form '_categoryName.attributeName'.
The terms category and attribute in PDBx jargon are analogous
table and column in relational data model, or class and attribute
in an object oriented data model.

The DataCategory class provides base storage container for instance
data and definition meta data.
