Identify the version of the Medium Identifier data type structure to which it applies. A Medium Identifier Structure Version comprises two parts: major and minor version numbers in the form: “major.minor”. Structures sharing the same major version have implied compatibility; structures having the same major version but different minor version numbers indicate the presence of compatible changes. The Medium Identifier Structure Version applicable to this issue of the standard is 1.0. The Medium Identifier data structure provides information that identifies the medium and its characteristics. Specifies an immutable unique identifier for the medium on which the Medium Identifier is recorded. The identifier is reused for the life of the medium, even if the medium is reformatted. The UUID is generated using the methods defined in RFC 4122 or ISO/IEC 9834-8. The business identifier of the medium, such as the value of a barcode label applied to the medium, a disk array volume label, a solid state memory device label, or some other identifying data item specific to the medium at the time of its preparation. Indicates the size, in bytes, of the data blocks recorded on the medium. Indicates the date and time that the medium was last prepared. Identifies the application that last prepared the medium. Specifies zero or more identifiers defined by the author of the Medium Identifier. (This field provides space for user-defined identifiers) Identifies the Entity that last prepared the medium. Identifies the Entity that owned the medium at the time it was last prepared.
