Abstract
Digital content, such as video, audio, multimedia, and similar files may be associated with metadata that is in some manner descriptive of the content by means of a unique identifier generated based on the content or a portion of the content. The two may be packaged in a wrapper. If the content is separated from the metadata, such as by circulation in a non-compliant environment, the content may be recognized by a regeneration of the identifier. Based upon the re-created identifier, the metadata may be re-associated with the content. Other scenarios may include generation of compilations for files that are not included in a wrapper with content and metadata, content that becomes dissociated with metadata by transcoding, and so forth.
