Dictionary types

Definition and purpose

A dictionary type is a name or identifier for the metadata for a dictionary. You create a coding map for a verbatim using a dictionary type.

The dictionary type specifies the metadata for all versions of a dictionary, including:

• Verbatim types.
• Dictionary levels.
• Dictionary level types, such as Term or Code.
• Where applicable, context meanings.

Dictionary types in the installation

The following dictionary types are installed with the Central Designer application:

• MedDRA—Medical Dictionary for Drug Regulatory Activities.
• MedDRAJ—Japanese version of the MedDRA dictionary.
• WHO-DD—World Health Organization Drug Dictionary (formerly WHO-DRL—World Health Organization Drug Reference List).
• JDrug—Japanese drug dictionary.

Importing

You can import other standard dictionary types as well as custom dictionary types in the Central Designer Administrator application.

For more information, see Importing and overwriting a dictionary type (in the Administrator Guide).

Multiple versions

The Central Designer application supports multiple versions of a dictionary type.

A version consists of dictionary metadata and dictionary data. In most cases, versions are different only in data, but new versions can also contain new metadata.

Using in a study or library

To use a coding dictionary in a study or library to create coding maps, you must use the following process:

1. Import the dictionary type (in the Administrator Guide).
2. Enable the dictionary type (in the Administrator Guide).
3. Select the dictionary type for a study or library.

Association with verbatim types

You can associate multiple verbatim types with a single dictionary type.

Deployment

Dictionary types that are used in the coding maps are deployed to the InForm application as MedML DICTIONARY objects.
