|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 Model.
|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, etc.).
|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.
