title: What's the difference between mediatype, contenttype and mimetype?
body: <p>Is there a difference between <em>mimetype</em>, <em>contenttype</em> and <em>mediatype</em>? (Java's JAX-RS <a href="http://jackson.codehaus.org/javadoc/jax-rs/1.0/javax/ws/rs/core/MediaType.html">MediaType</a>). </p>
  
  <p>From the <a href="http://en.wikipedia.org/wiki/Internet_media_type">wikipedia article</a> i gathered that it's only a content-type in the context of e.g. HTTP requests as a field in a request's header: So are these just synonyms or are there any actual semantic differences between the different terms?</p>
