Assigns one or more tags (key-value pairs) to the specified Amazon Location Service resource. <p>Tags can help you organize and categorize your resources. You can also use them to scope user permissions, by granting a user permission to access or change only resources with certain tag values.</p> <p>You can use the <code>TagResource</code> operation with an Amazon Location Service resource that already has tags. If you specify a new tag key for the resource, this tag is appended to the tags already associated with the resource. If you specify a tag key that's already associated with the resource, the new tag value that you specify replaces the previous value for that tag. </p> <p>You can associate up to 50 tags with a resource.</p>
