The DMI Project Logical Data Model describes the sought after DMI Asset Metadata Structure represented
using UML Class Modelling diagrams. The model is describing the structure on a class level, but where
possible examples have been added to explain how the structure works.
The current version has not been fully populated with attributes but the required data structures should be in
The model covers all types of media assets, not just linear television programmes. The structure of the
model is supporting Linear Television Programmes, Radio Programmes, Interactive Services, Promotions,
Web Pages, Interstitials and Scripts etc. Several areas will require further analysis; this will be highlighted in
the detail of the document. It is expected that this will be looked at in the detailed design phase.
One of the main focuses of the model is that the asset information should be held separately from
information about the usage of that asset; this will simplify the reuse of the assets, from an information point
of view. The concepts Publishable Asset and Media Asset have been introduced to the model to support this
separation of the data.
