#### X.6.1.3 Conformance Requirements

An implementation may conform to one of the Color Palette Information Model SOP Classes as an SCU, SCP or both. The Conformance Statement shall be in the format defined in PS3.2.

##### X.6.1.3.1 SCU Conformance

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

An implementation that conforms to one of the Color Palette Information Model SOP Classes shall support queries against the Color Palette Information Model using the C-FIND SCU Behavior described for the Basic Worklist Management Service Class (see Section K.4.1.2 and Section X.4.1).

An implementation that conforms to one of the Color Palette Information Model SOP Classes 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 one of the Color Palette Information Model SOP Classes 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.

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

An implementation that conforms to one of the Color Palette Information Model SOP Classes as an SCU shall support transfers against the Color Palette 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 X.4.2).

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

An implementation that conforms to one of the Color Palette Information Model SOP Classes as an SCU shall support transfers against the Color Palette Information Model using the C-GET SCU baseline behavior described for the Query/Retrieve Service Class (see Section C.4.3.2.1 and Section X.4.3).

##### X.6.1.3.2 SCP Conformance

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

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

An implementation that conforms to one of the Color Palette Information Model SOP Classes 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 one of the Color Palette Information Model SOP Classes 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.

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

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

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

An implementation that conforms to one of the Color Palette Information Model SOP Classes as an SCP shall support transfers against the Color Palette Information Model using the C-GET SCP baseline behavior described for the Query/Retrieve Service Class (see Section C.4.3.3.1).

An implementation that conforms to one of the Color Palette Information Model SOP Classes as an SCP, which generates transfers using the C-GET operation, shall state in its Conformance Statement the Color Palette Storage Service Class SOP Class under which it shall support the C-STORE sub-operations generated by the C-GET.

#### X.6.1.4 SOP Classes

The SOP Classes of the Color Palette Information Model in the Color Palette Query/Retrieve Service Class identify the Color Palette Information Model, and the DIMSE-C operations supported. The following Standard SOP Classes are identified:
