Abstract: Improved management of digital media assets within an on-line media repository are disclosed. In one embodiment, the management includes methods and systems for identifying distinct digital media assets that are equivalent to one another. In one implementation, a plurality of digital media assets described and/or stored in a media storage device (e.g., database) can be automatically examined to determine whether any of them match one another or match a new digital media asset. Those digital media assets that are considered equivalent can be treated as such by an on-line store so as to facilitate customer interaction.
