UDF 2.00 - OSTA - Optical Storage Technology Association

implementation specific. The intended purpose of this descriptor is to aid in the
identification of a Volume within a Volume Set that belongs to a specific Logical
Volume.
NOTE: An implementation may still record an additional Implementation Use
Volume Descriptor in its own format on the media. The UDF Implementation Use
Volume Descriptor does not preclude an additional descriptor.
2.2.7.1 EntityID Implementation Identifier
This field shall specify “*UDF LV Info”.
2.2.7.2 bytes Implementation Use
The implementation use area shall contain the following structure:
struct LVInformation {
struct charspec
dstring
dstring
dstring
dstring
struct EntityID
bytes
}
LVICharset,
LogicalVolumeIdentifier[128],
LVInfo1[36],
LVInfo2[36],
LVInfo3[36],
ImplementionID,
ImplementationUse[128];
2.2.7.2.1 charspec LVICharset
$ Interpreted as specifying the character sets allowed in the
LogicalVolumeIdentifier and LVInfo fields.
.
? Shall be set to indicate support for CS0 only as defined in 2.1.2.
2.2.7.2.2 dstring LogicalVolumeIdentifier
Identifies the Logical Volume referenced by this descriptor.
2.2.7.2.3 dstring LVInfo1
The fields LVInfo1, LVInfo2 and LVInfo3 should contain additional information
to aid in the identification of the media. For example the LVInfo fields could
contain information such as Owner Name, Organization Name, and Contact
Information.
2.2.7.2.4 struct EntityID ImplementionID
Refer to the section on Entity Identifier.
