# Code Directory

### Definition

The definition of a [Terminology](/standards/dci/terminology.md#code-directory)is documented in the Terminology section.

#### Language and Localization

The definitions documented in the Code directory section are language-agnostic and intended to be used consistently across different countries and system implementations.

Countries and implementing partners may create localized profile versions, including labels and descriptions in the language(s) of their preference. In all cases, the underlying codes must remain unchanged and aligned with the standardized definitions.

This approach ensures interoperability and semantic consistency at the data level, while allowing flexibility for national languages and local user needs at the presentation and user-interface level.

### Data Type

{% hint style="info" %}
The data type for all code directories is [DT.COM.02 string](/standards/standards-for-interoperability-interfaces/common-standards-for-interoperability-interfaces/data/data-types-and-formats/dt.com.02-string.md).
{% endhint %}
