## V.6 SOP Class Definitions

### V.6.1 Product Characteristics Query SOP Class

#### V.6.1.1 Product Characteristics Query SOP Class Overview

The Product Characteristics Query SOP Class defines an application-level class of service that facilitates the communication of detailed information about drugs, contrast agents, or devices identified by a bar code or similar identifier. The detailed information is intended to be used both for automated processing and for presentation to a system operator.

The Product Characteristics Query SOP Class supports the following example use cases:

- Obtain the active ingredient, concentration, or other parameters of a contrast agent for inclusion in the image SOP Instances created during use of the agent, or for setting up image acquisition parameters (e.g., ultrasound transducer frequency)

- Obtain the size parameters of a device (e.g., a catheter) for use in calibrating images that show that device

- Obtain a network reference for an online copy of the "product label" (regulated prescribing and use data) for a drug, contrast agent, or device.

#### V.6.1.2 Product Characteristics Query Information Model

##### V.6.1.2.1 E/R Model

The Product Characteristics Query Information Model is represented by the Entity Relationship diagram shown in figure Section V.6 -1.

Figure V.6-1. Product Characteristics E-R Diagram

There is only one Information Entity in the model, which is the Product. The Attributes of a Product can be found in the following Module in PS3.3.

- Product Characteristics Module

##### V.6.1.2.2 Product Characteristics Query Attributes

Table V.6-1 defines the Attributes of the Product Characteristics Query Information Model:

Table V.6-1. Attributes for the Product Characteristics Query Information Model

Description / Module | Tag | Matching Key Type | Return Key Type | Remark/Matching Type
--- | --- | --- | --- | ---
Product Package Identifier | (0044,0001) | R | 1 | Shall be retrieved with Single Value Matching only.
Product Type Code Sequence | (0044,0007) | - | 1 |
>Include Table 8-3a “Enhanced SCU/SCP Coded Entry Macro with no SCU Support and no Matching Key Support”
Product Name | (0044,0008) | - | 1 |
Product Expiration DateTime | (0044,000B) | - | 2 |
Product Parameter Sequence | (0044,0013) | - | 2 |
>Value Type | (0040,A040) | - | 1 |
>Concept Name Code Sequence | (0040,A043) | - | 1 |
>>Include Table 8-3a “Enhanced SCU/SCP Coded Entry Macro with no SCU Support and no Matching Key Support”
>All other Attributes of the Product Parameter Sequence |  | - | 1C | Conditional on value of Value Type (0040,A040); See PS3.3 Content Item Macro.
All other Attributes of the Product Characteristics Module |  | - | 3 |

The Product Package Identifier (0044,0001) might not be globally unique and might conflict with other identifiers used within the scope of the institution.

### Note

The package identifiers are typically unique within the scope of the substance administration management systems. This is a warning that they are not UIDs.

#### V.6.1.3 Conformance Requirements

An implementation may conform to the Product Characteristics Query SOP Class as an SCU or an SCP. The Conformance Statement shall be in the format defined in PS3.2.

##### V.6.1.3.1 SCU Conformance

An implementation that conforms to the Product Characteristics Query SOP Class shall support queries against the Information Model described in Section V.6.1.2 using the baseline C-FIND SCU Behavior described in Section V.4.1.2.

An implementation that conforms to the Product Characteristics Query SOP Class as an SCU shall state in its Conformance Statement the Return Key Attributes it requests, and how those Attributes are used in the application.

An implementation that conforms to the Product Characteristics Query 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.

##### V.6.1.3.2 SCP Conformance

An implementation that conforms to the Product Characteristics Query SOP Class shall support queries against the Product Characteristics Query Information Model described in Section V.6.1.2 using the C-FIND SCP Behavior described in Section V.4.1.3.

An implementation that conforms to the Product Characteristics Query SOP Class as an SCP shall state in its Conformance Statement the Return Key Attributes that it supports.

An implementation that conforms to the Product Characteristics Query SOP Class as an SCP shall state in its Conformance Statement how it makes use of Specific Character Set (0008,0005) when encoding responses.

#### V.6.1.4 SOP Class
