Here is an example of how real recordings
and scores might fit into the Variations2 Data Model.
A CD titled “Mozart, Piano Works” would represent the container level in the Data
The recordings of two different pieces on this CD—Sonata K.279 and Fantasia K.397—would
become instantiations, each having its own properties (recording date, place,
The performers of these recordings would receive appropriate Contributor records
with their own attributes (dates of birth, etc.). This is especially valuable
because unlike in the USMARC system, Variations2 Data Model accommodates very
clear and precise linking of performers and works.
Each of the instantiations would be linked to an abstract work record, with
its own “global” work properties. The work record, in its turn, is linked to
its contributor, the composer Wolfgang Amadeus Mozart.
A score would be accommodated in a similar way. For example, a score of the Piano
Fantasia K. 397 would be linked to its instantiation, which would be related
to the appropriate work and its contributor.
