Managing D igital Assets: A Coll a borative Ca m pus-Wide Exploration of Infrastructure and Application s University of Michigan Lynn Johnson, Ph.D., School of Dentistry Louis E. King, Digital Media Commons EDUCAUSE Midwest Regional Conference April 21, 2004
The use of text based search engines to expose the content of rich media by searching metadata created by video and audio analysis tools. (voice to text, voice & facial recognition, optical character recognition, etc.)
IBM and our identified partners will deliver an end-to-end digital asset management system to the “Living Lab” as a working demonstration environment.
IBM and the University of Michigan will identify areas for collaborative research projects around subjects such as digital rights, open standards, and learning technologies.
IBM and the University of Michigan will use the Lab to support the delivery of pilot projects that will be used to explore a variety of existing and emerging digital asset management technologies.
IBM and the University of Michigan will co-create a marketing and communications program to promote the Lab’s efforts across campus, to the Big Ten CIC, to other higher education organizations and the Merlot consortium.

Copyright issues must be addressed in a systemic way – UMCore metadata schema will likely require a rights declaration
Digital Rights Management modules may be more cost effective managing regulatory issues such as FERPA (Family Educational Rights and Education Act) and HIPAA (Health Insurance Portability and Accountability Act)
Education, training, and support on metadata and file quality will help distribute the work load and maximize the ability to share materials
Ongoing interface design to meet project and user requirements. (Taking into consideration asset management’s inherently different approach of presenting multiple items, each of which may have a different set of user capabilities associated with it)
Integration with other academic tools or portal.
Relationship to Library, Institutional Repository and federated catalogue searching.
IP, Copyright, Use and Misuse policy.
Building a great user experience.
