Data Model
There are 3 primary entities in the VRA Core 4.0 data model: collection, work, and image. The primary
focus of description in VRA Core is the work record which can then be affiliated with one or more images
via the Relation element. By the same token, a single image can relate to one or more works when for
example a documentary image is taken of an exhibition and that image portrays multiple works. A
collection record can be used to aggregate multiple work or multiple image records.
