A method for identifying the contents of a compact disc manipulating a received table of contents (TOC) identifier associated with the compact disc. The method parses portions of the TOC comprising a series of numbers corresponding to track offsets for each track of the compact disc. The method further determines the first number from the series of numbers, subtracts the first number from each number in the series of numbers to form an altered series of numbers, and concatenates the altered series of numbers to form an altered string that comprises the altered TOC identifier. The altered TOC identifier may then be compared to a plurality of canonical TOC identifiers to identify the contents of the compact disc. Another method generates a generic TOC identifier for a plurality of compact discs known to contain the same data.

Enhanced table of contents (TOC) identifiers

Providing standardized metadata associated with media content responsive to input metadata. The invention extracts one or more tokens from the input metadata. Each of the extracted tokens represents a portion of the input metadata. The invention creates a token group comprising a plurality of selected tokens. The invention searches the database of standardized metadata using a multi-pass approach using the token group and the extracted tokens to identify the standardized metadata associated with the input metadata.

Matching media file metadata to standardized metadata

A media identifier registry for managing metadata records. The registry stores a unique logical identifier for each of the records as well as a base type corresponding to each of the logical identifiers. The base types are representative of the information contained in the respective metadata records for the corresponding logical identifiers. The registry further defines associations between the logical identifiers and base types. Improvements in identifying media content and related information according to the invention permit building a media data warehouse capable of aggregating data from many different sources, uniquely identify the same piece of content from different data providers, in different cultures, and in different physical forms to allow a consistent set of data to be stored and retrieved.
