Global Digital Format Registry (GDFR) Data Model, v.5.0.4 [ Octoeber 21, 2006 ]
GDFR-Data-Model-5_0_4.rtf [ RTF ]

A model in which family and format are considered different types of the same conceptual entity, although classification remains distinct. "Family" refers to abstract format families rather "format" refers to concrete formats. This represents a somewhat incompatible change for the PRONOM-compliant v.5.0.3 model described below.

Global Digital Format Registry (GDFR) Data Model, v.5.0.3 [ October 21, 2006 ]
GDFR-Data-Model-5_0_3.rtf [ RTF ]

Based on the PRONOM information model in which classification, family, and format are separate conceptual entities.
