## II.6 SOP Class Definitions

### II.6.1 Protocol Approval Information Model

#### II.6.1.1 E/R Models

The Protocol Approval Information Model consists of a single entity. In response to a given C-FIND request, the SCP shall send one C-FIND response per matching Protocol Approval Instance.

#### II.6.1.2 Protocol Approval Attributes

Table II.6-1 defines the Attributes of the Protocol Approval Information Model.

### Note

Since protocol approvals are generally relevant only in the context of the protocol instance being approved, many searches will be looking for approvals that list a particular protocol instance in the Approval Subject Sequence (0044,0109).

Table II.6-1. Attributes for the Protocol Approval Information Model

Description / Module | Tag | Matching Key Type | Return Key Type | Remark / Matching Type
--- | --- | --- | --- | ---

### Note

The Enhanced General Equipment Module describes the equipment that created the Protocol Approval instance, not the equipment on which a referenced Protocol will be performed.

#### II.6.1.3 Conformance Requirements

An implementation may conform to one or more of the Protocol Approval Query/Retrieve SOP Classes as an SCU or SCP. The Conformance Statement shall be in the format defined in PS3.2.

##### II.6.1.3.1 SCU Conformance

###### II.6.1.3.1.1 C-FIND SCU Conformance

An implementation that conforms to the Protocol Approval Information Model - FIND SOP Class shall support queries against the Protocol Approval Information Model using the C-FIND SCU Behavior described for the Basic Worklist Management Service Class (see Section K.4.1.2 and Section II.4.1).

An implementation that conforms to the Protocol Approval Information Model - FIND SOP Class as an SCU shall state in its Conformance Statement whether it requests Type 3 Return Key Attributes, and shall list these Optional Return Key Attributes.

An implementation that conforms to the Protocol Approval Information Model - FIND SOP Class as an SCU shall state in its Conformance Statement how it makes use of Specific Character Set (0008,0005) when encoding queries and interpreting responses.

###### II.6.1.3.1.2 C-MOVE SCU Conformance

An implementation that conforms to the Protocol Approval Information Model - MOVE SOP Class as an SCU shall support transfers against the Protocol Approval Information Model, using the C-MOVE SCU baseline behavior described for the Query/Retrieve Service Class (see Section C.4.2.2.1 and Section II.4.2).

###### II.6.1.3.1.3 C-GET SCU Conformance

An implementation that conforms to the Protocol Approval Information Model - GET SOP Class as an SCU shall support transfers against the Protocol Approval Information Model, using the C-GET SCU baseline behavior described for the Query/Retrieve Service Class (see Section C.4.3.2).

##### II.6.1.3.2 SCP Conformance

###### II.6.1.3.2.1 C-FIND SCP Conformance

An implementation that conforms to the Protocol Approval Information Model - FIND SOP Class as an SCP shall support queries against the Protocol Approval Information Model, using the C-FIND SCP Behavior described for the Basic Worklist Management Service Class (see Section K.4.1.3).

### Note

The contents of the Referenced SOP Instance UID (0008,1155) in the Approval Subject Sequence (0044,0109) would be useful to index since querying for approvals of a specific Protocol instance will be very common.

An implementation that conforms to the Protocol Approval Information Model - FIND SOP Class as an SCP shall state in its Conformance Statement:

- whether it supports Type 3 Return Key Attributes, and shall list these Optional Return Key Attributes.

- how it makes use of Specific Character Set (0008,0005) when interpreting queries, performing matching and encoding responses.

- any behaviors that involve not returning matching instances (e.g. not returning an older approval instance that has been superceded/overridden by a newer approval instance).

###### II.6.1.3.2.2 C-MOVE SCP Conformance

An implementation that conforms to the Protocol Approval Information Model - MOVE SOP Class as an SCP shall support transfers against the Protocol Approval Information Model, using the C-MOVE SCP baseline behavior described for the Query/Retrieve Service Class (see Section C.4.2.3.1).

An implementation that conforms to the Protocol Approval Information Model - MOVE SOP Class as an SCP, which generates transfers using the C-MOVE operation, shall state in its Conformance Statement appropriate Storage Service Class, under which it shall support the C-STORE sub-operations generated by the C-MOVE.

###### II.6.1.3.2.3 C-GET SCP Conformance

An implementation that conforms to the Protocol Approval Information Model - GET SOP Class as an SCP shall support retrievals against the Protocol Approval Information Model using the C-GET SCP baseline behavior described for the Query/Retrieve Service Class in Section C.4.3.3.

#### II.6.1.4 SOP Classes

The SOP Classes of the Protocol Approval Query/Retrieve Service Class identify the Information Models, and the DIMSE-C operations supported.

Table II.6.1.4-1. Protocol Approval SOP Classes

SOP Class Name | SOP Class UID
--- | ---
Protocol Approval Information Model - FIND | 1.2.840.10008.5.1.4.1.1.200.4
Protocol Approval Information Model - MOVE | 1.2.840.10008.5.1.4.1.1.200.5
Protocol Approval Information Model - GET | 1.2.840.10008.5.1.4.1.1.200.6
