title: How to read XMI?
body: <p>I need to read UML diagrams that are serialized into XMI. Is there any library that would allow me to conveniently read UML XMI - by conveniently I mean having some methods to iterate over classes/packages/methods/attributest etc. in model.</p>
  
  <p>I tried EMF, but I am unable to find any tutorial that would show how to import XMI containing UML. I have also found <a href="http://nsuml.sourceforge.net/" rel="noreferrer">NSUML/NSMDF</a> but the link to documentation is broken. </p>
