Check out this lovely metadata scheme for art and architecture images created by the University of Oregon Libraries Digital Images Initiative. Part crosswalk and part data dictionary, this simple scheme (UO-AAI) combines the best of VRA Core and Dublin Core. Authorities are clearly delineated with the usual suspects of ULAN, TGN and AAT at the forefront and it provides a solid framework for anyone seeking to manage a digital visual resource collection.
Ostensibly, this scheme was created to manage the rich resources available at UO’s Art and Architecture Library. Collections range from those originating from Oregon libraries like Oregon Digital, a joint effort by OSU and UO to the standard issue Artstor or Oxford Art Online.
