title: Rel on REST API collection links
body: <p>I'm working on a REST API, and one of my resources is a collection of other resources, so I should return something like that:</p>
  
  <pre><code>{
      "Links":[
          {
              "Href":"http://my.rest.api/document/1",
              "Rel":"something"
          },
          {
              "Href":"http://my.rest.api/document/2",
              "Rel":"something"
          }
      ]
  }
  </code></pre>
  
  <p>My question is about the "rel" property. I don't really understand its use. Is it something to specify which HTTP method to use? Can somebody explain me?</p>
  
  <p>Thanks a lot</p>
