VRA Core Metadata Element Set
This is a metadata standard for describing works of visual culture and the images that document them. Developed by the Visual Resources Association, the current version is VRA Core 3.0; a new version VRA Core 4.0 is now at Beta Draft stage and the XML schema is available from the VRA website. Beta testing was scheduled to take place in December 2005 and January 2006, with finalization of the schema planned for March 2006.
A work is a physical entity that exists, has existed at some time in the past, or could exist in the future. Works may be single items or consist of many parts, and might be:
An image is a visual representation of a work. It can exist in photomechanical, photographic and digital formats. In a typical visual resources collection, an image is a reproduction of the work that is owned by the cataloguing institution and is typically a slide, photograph or digital file. A visual resources collection may own several images of a given work.
In VRA Core 3.0, separate records are created for the work and image(s). One element in the elements set denotes Record Type; this defines whether it is a work or an image that is being described.
There can also be relationships between two or more works. Essential relationships exist where the described work includes the referenced work, either physically or logically within a larger to smaller context. With works that have an essential relationship, it is recommended that the Title.LargerEntity qualifier always accompany the title for the part.
An informative relationship between two works exists when the described and referenced works could stand independently and the relationship is informative but not essential either physically or logically in identifying either of the works. The link between the works should be reciprocal.
