title: Using a RESTFUL PUT, how should parent/child entities be updated (or informed)?
body: <p>For a simple example, I'll use tires and cars. I intend to execute a PUT to increase the price of a tire. The UI also contains cars that use the tires being updated, therefore requiring a price update of their own.</p>
  
  <p>Is it appropriate for the original PUT request to contain car pricing in its response? If not, how is this typically solved?</p>
