<p>Add one or more tags (keys and values) to a specified application. A <i>tag</i> is a label that you optionally define and associate with an application. Tags can help you categorize and manage application in different ways, such as by purpose, owner, environment, or other criteria. </p> <p>Each tag consists of a required <i>tag key</i> and an associated <i>tag value</i>, both of which you define. A tag key is a general label that acts as a category for more specific tag values. A tag value acts as a descriptor within a tag key.</p>
