### F.5.23 Presentation State 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 "PRESENTATION". Table F.5-23 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 Softcopy Presentation State Storage and Structured Display IODs. This Directory Record shall be used to reference a Softcopy Presentation State Storage SOP Instance or a Structured Display SOP Instance. 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.
