## Overview

This solution sets up a Taxonomy called “Region” that contains a list of countries, and each country has term UID. Then an Automation is created that does the following:

- Listens to the “Create Entry” event for a particular content type.


- Sets up mappings from locale codes to country term UIDs.


- If the country does not have the mapping, it will set the default term UID as 'usa'.



Example: Country “Netherlands” term UID is netherlands.

## Tactical Rundown

- Create the following Taxonomy in a stack:

- Create a Content Type which also has the Taxonomy field where the locale can be stored.

- Create an Automation to fill the Region term based on the present entry's language.

- With the Contentstack connector create an Entry Trigger for any new entry created based on the particular Content Type.

- Use the CodeBlock connector with the following JavaScript Code:

```
const mapping = {'sw':'sweden', 'en-us':'usa', 'en-uk':'england', 'nl-nl':'netherlands', 'de-de':'germany'};
return mapping[input.locale] || 'usa';
```

Here's how it looks:

- Use the HTTP connector to update an entry based on the localized country of the entry.

Examples:

- When the entry created in default locale, the term is set as “usa,” and when the entry gets localized into Dutch, the term is set as “netherlands.”


- Based on the above automation steps, when the entry is localized in Germany, the term is automatically added.

## Frequently asked questions

### How does Contentstack assign taxonomy terms based on locale?

By setting up a mapping from locale codes to country term UIDs and using an automation workflow, Contentstack can automatically assign the appropriate taxonomy term to an entry based on its locale.

### What happens if a locale does not have a mapping?

If a locale doesn't have a specific mapping, the system will assign the default term UID, which in this example is 'usa'.

### What tools are used to automate term assignment in Contentstack?

Automations use Contentstack's connectors including Entry Triggers, CodeBlock with JavaScript, and HTTP connectors to update entries and assign taxonomy terms.
