Element track is used to describe single tracks. Please note that this element can be used also to link videos whose audio component refers to the piece. Detailed information about catalog metadata and event indexing are contained in its sub-elements (see the following).

 

Attributes
  • file_name, the path to locate the digital object. The path should use only slash and backslash characters as directory separators. The value of this attribute should respect the syntax rules supported by POSIX and MS-DOS/Windows operating systems.
  • file_format, extracted from a complete list of supported formats presented in the IEEE 1599 DTD. IEEE 1599 formats are similar to the corresponding MIME media type, but media type name (e.g., “audio”) and subtype name (e.g., “mp3”) are separated by an _ (underscore) character. As a consequence, a MIME type such as “audio/mp3” is expressed in IEEE 1599 as “audio_mp3.”
  • encoding_format (see file_format for allowed values). There is usually no difference between file format and encoding format, but some formats (such as TIFF for graphics and WAV for audio) can be considered containers of a number of other formats. In this case, file_format reflects the “external” encoding whereas encoding_format specifies the actual encoding within the container.
  • md5, an attribute to represent the cryptographic hash function known as MD5 (Message-Digest algorithm 5). As an Internet standard (RFC 13219), MD5 has been employed in a wide variety of security applications, and is also commonly used to check the integrity of files. An MD5 hash is typically a 32-character hexadecimal number.
