title: How "store" REST archetype isn't creating a new resource and a new URI?
body: <p>REST API design indicates there are four resources archetypes: document, collection, store and controller.  </p>
  
  <p>Store do not create new resources; therefore a store never generates new URIs.</p>
  
  <p>An example:</p>
  
  <pre><code>PUT /users/12245/favorites/boston-celtics
  </code></pre>
  
  <p>A user added Boston Celtics to his favorites list.</p>
  
  <p>But how that isn't creating a new resource ? and how it isnt generating a new URI?  </p>
