The Oakland Museum of California (OMCA) is a multi-disciplinary museum with nearly 3 million objects in its collection. It is a consolidated museum that stewards three major disciplines (Art, History, and Natural Science). As a reflection of this, the DAMS at OMCA is also a multi-subject, multi-disciplinary resource for the museum's operational needs. Throughout the system's implementation, our assumptions have changed as the user base has grown. We are adapting our DAM to serve these needs, and we view OMCA’s DAM as a living system that requires constant transformation as it matures.
