## F.5 Definition of Specific Directory Records

The following Sections specify a number of Directory Records that were introduced by the Basic Directory IOD Information Model presented in Section F.4. For each one, it identifies the SOP Classes that may be referenced and the related mandatory keys. Keys are assigned a Type designation that indicates if it is required for all Media Storage Operations of the Directory (see Section 5).

Type 2 and Type 3 Keys may be changed to Type 1 and Type 2 or 3 respectively by Application Profiles defined in PS3.11. Keys based on Private Data Elements, or Private Keys may also be used in addition to Standard defined Keys. However such Private keys may be ignored by any File-set Reader or Updater.
