# Dictionary Domain Tab

## Creating a Domain

If you create an Entity with **Import CSV,** attributes and domains are auto-generated based on a dataset. See [Generate Entity from CSV](#generate-entity-from-csv) for more information. Otherwise, click the **Add Domain** button to open the domain editing window. 

{% hint style="info" %}
In general, attributes with coded terms will have a defined domain (e.g. the domain for gender might be "F","M"). Attributes with unlimited possible values will not have a defined domain (e.g. Year).
{% endhint %}
