Digital Item Declaration Object

Object

object representation in the Digital Item Method Language of a Digital Item Declaration element and associated with an Object Type

Note 1 to entry: A Digital Item Declaration Object has an Object Type that allows it to be processed in a Digital Item Method according to the Object Type. A Digital Item Declaration element is mapped to an Object Type by the Object Map.

Note 2 to entry: An Object Type is associated with a Digital Item Declaration element by an ObjectType element contained in a Descriptor-Statement child of the Digital Item Declaration element. For further information see 5.3.

Note 3 to entry: The capitalized term Object is used in this part of ISO/IEC 21000 to mean a Digital Item Declaration Object. Other uses of the term object without an initial uppercase letter is used for an object as understood in the context of object-oriented programming.
