### F.5.40 Plan Directory Record Definition

The Directory Record is based on the specification of Section F.3. It is identified by a Directory Record Type of Value "PLAN". Table F.5-40 lists the set of keys with their associated Types for such a Directory Record Type. The description of these keys may be found in the Modules related to the Plan IEs of RT Plan IOD and RT Ion Plan IOD. This Directory Record shall be used to reference one of the class of Plan SOP Instances having a Modality (0008,0060) of "PLAN", such as the RT Beams Delivery Instruction IOD. This type of Directory Record may reference a Lower-Level Directory Entity that includes one or more Directory Records as defined in Table F.4-1.

Table F.5-40. Plan Keys

Key | Tag | Type | Attribute Description

Specific Character Set | (0008,0005) | 1C | Required if an extended or replacement character set is used in one of the keys.
