title: What is the difference between IRI and URI in OWL?
body: <p>Example: </p>
  
  <pre><code>http://data.doremus.org/activity/587ae689-790e-3525-9e3a-dac63f449a03
  </code></pre>
  
  <p>I think it is a IRI and also a URI. (Am I right?)</p>
  
  <p>And I use OWL API to parse it. In the class "IRI", there is a method <code>getShortForm()</code>, when I use it, I get "ae689-790e-3525-9e3a-dac63f449a03". </p>
  
  <p>About URI, I think its local name is "587ae689-790e-3525-9e3a-dac63f449a03". I am not very sure. In fact, I know the word "local name" from others' blog. I don't find the "local name" in URI's structure as follows.</p>
  
  <blockquote>
  <pre><code>scheme:[//[user[:password]@]host[:port]][/path][?query][#fragment]
  </code></pre>
  </blockquote>
  
  <p>So, I have two questions: </p>
  
  <ol>
  <li><p>What's the shortForm of IRI? Why the shortForm of the example is not "587ae689-790e-3525-9e3a-dac63f449a03"?</p></li>
  <li><p>What's the local name of URI and what's the local name of the example?</p></li>
  </ol>
