#### HH.6.1.3 Conformance Requirements

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

##### HH.6.1.3.1 SCU Conformance

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

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

An implementation that conforms to the Defined Procedure Protocol 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 Defined Procedure Protocol 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.

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

An implementation that conforms to the Defined Procedure Protocol Information Model - MOVE SOP Class as an SCU shall support transfers against the Defined Procedure Protocol 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 HH.4.2).

### Note

The contents of the Model Specification Sequence (0018,9912) would be useful to index for systems that support query or selection of appropriate Protocols for specific systems.

An implementation that conforms to the Defined Procedure Protocol 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.

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

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

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

### Note

It is expected that a device that does not match the contents of the Model Specification Sequence (0018,9912) will not execute the Protocol.

An implementation that conforms to the Defined Procedure Protocol 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.

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

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

#### HH.6.1.4 SOP Classes

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