# Tag-based Policies
<a name="tag-based-policies"></a>

Amazon SWF supports policies based on tags. For instance, you could restrict Amazon SWF domains that include a tag with the key `environment` and the value `production` with the following condition:

```
"Condition": {
    "StringEquals": {"aws:ResourceTag/environment": "production"}
}
```
