Abstract: A unique material identifier (UMID) for a media file that was not provided with a UMID at its point of origination is generated by using the content of the file, and is independent of the time of file import or accessing. For a given item of media material, the UMID remains unchanged and uniquely identifies the item when such a file is imported or accessed multiple times. The UMID may be generated by hashing together selected portions of the metadata and essence of the media file. The amount of metadata and essence sampled is chosen to provide a high degree of assurance that the UMID will be unique, but is kept small enough so as to avoid causing a perceptible lag when the UMID is generated. In various embodiments the UMID is based purely on one or more selected portions of the media file essence.
