"The Sorting of Competing Metadata Models in Digital Asset Management" is an article I wrote with my DAM team.  It was published back in the spring in the Journal of Digital Media Management, and I get questions about this from time to time, so I thought I'd post it here for linking and reference.

This article owes much to Jenn Riley's "Seeing Standards: A Visualization of the Metadata Universe".  I have a six foot print of Riley's metadata map on the wall of my cube.  You can see it yourself at http://www.dlib.indiana.edu/~jenlrile/metadatamap/

If you're going to connect DAMs, or create a federated search engine across systems, I recommend deciding on a core metadata set that can be shared across platforms first.  It only needs to be ten fields or so, and don't worry - you don't have to lose data.  The refined metadata model from your multiple systems can reside still in each of those silos, while your one true metadata models gives searchability.  I saw several people struggling with this at #DAMLA, so I thought I would share.  Enjoy!  And build yourself some PPTPs to float your metadata from place to place.
