title: MIME Type of Wavefront's OBJ and MTL
body: <p>I was building a little 3D-application using ThreeJS and WebGL. I purposely chose not to convert models into ThreeJS compatible .json files, instead started building an importer. It works, but I also planned to have the application decide what type of model has been loaded using both file extension and MIME type, the later if the first is unknown.</p>
  
  <p>I've read somewhere that the MIME Type is supposed to be <code>application/wavefront-obj</code>, which would be kind of weird since there is also the <code>model</code> tree, but okay anyways. Though browsing the IANA website for this file type yields no results.</p>
  
  <p>Am I missing something?</p>
