An encoded Information Object Definition (IOD) Attribute that is composed of, at a minimum, three fields: a Data Element Tag, a Value Length, and a Value Field. For some specific Transfer Syntaxes, a Data Element also contains a VR Field where the Value Representation of that Data Element is specified explicitly. Data Element Tag A unique identifier for a Data Element composed of an ordered pair of numbers (a Group Number followed by an Element Number). Value A component of a Value Field. A Value Field may consist of one or more of these components. Value Field The field within a Data Element structure that contains the Value(s) of that Data Element.
