<p>Optional metadata that you assign to a resource. You can specify a maximum of five tags for an OpsMetadata object.

In this case, you could specify the following key-value pairs:</p> <ul> <li> <p> <code>Key=Environment,Value=Production</code> </p> </li> <li> <p> <code>Key=Region,Value=us-east-2</code> </p> </li> </ul>
