title: Is an API RESTful if it only uses GET/Retrieve
body: <p>If an API only allows retrieval of data (through GET) and does not allow Create, Update or Delete is it still RESTful? </p>
  
  <p>I question this because Wikipedia says "When a client holds a representation of a resource, including any metadata attached, it has enough information to modify or delete the resource." as a constraint of REST.</p>
  
  <p>I'm sorry if this seems like a silly question but I'm trying to get to the point where I can say 'I understand REST' confidently. </p>
