## I.4 Media Storage Standard SOP Classes

The SOP Classes in the Media Storage Service Class identify the Composite IODs to be stored. The following Standard SOP Classes are defined:

- all SOP Classes specified for the DIMSE C-STORE based Storage Service Class identified in Table B.5-1

- all SOP Classes specified for the DIMSE C-STORE based Non-Patient Object Storage Service Class identified in Table GG.3-1

- the media directory SOP Class identified in Table I.4-1

Table I.4-1. Media Storage Standard SOP Classes

SOP Class Name | SOP Class UID | IOD Specification (defined in PS3.3)
--- | --- | ---
Media Storage Directory Storage | 1.2.840.10008.1.3.10 | Basic Directory IOD

### Note

1. Except for the Media Storage Directory SOP Class, all the SOP Classes in the Media Storage Service Class are assigned the same UID Value as the corresponding network communication SOP Classes. This was done to simplify UID assignment. Although these SOP Classes are based on different Operations, the context of their usage should unambiguously distinguish a SOP Class used for Media Storage from a network communication SOP Class.

2. The storage of Normalized Print SOP Instances on media was previously defined in DICOM. They have been retired. See PS 3.4-1998.

3. The storage of Detached and Standalone SOP Instances on media was previously defined in DICOM. They have been retired. See PS 3.4-2004
