title: protege how to add a data property to an object property (from different ontologies)
body: <p>First I will list how I was doing what I want to do when I had just one Ontology, then I will list my question with two ontologies just to give you the full context of my problem. (and excuse me if i used the words such as properties in wrong context, that is why I will add pictures to support my question)</p>
  
  <p>When I had just one ontology, I had an Object Property, and I could add property (you may call it annotation) for it like this:
  <a href="https://i.stack.imgur.com/VTOeb.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/VTOeb.png" alt="enter image description here"></a></p>
  
  <p>It was simple, just click on add annotation, and create a new annotation called "degreeBy" and set the value.</p>
  
  <p>However, now I have two ontologies (the same example but different name for the properties), where I have a data property in one ontology and an object property in another ontology.</p>
  
  <p>I created a thrid ontology in protege by importing the two ontologies.
  so now I have <strong>in the object property section</strong>:

  <p>where <code>hasFeature</code> is an object property coming from the first ontology, and I have <strong>in the data property section</strong>:</p>

  <p>where <code>hasSimilarityValue</code> is a data property (with range double) coming from the second ontology.</p>
  
  <p>Now I want to say that the <code>hasFeature</code> property has <code>hasSimilarityValue</code> with a specific value. As I showed you, this was easy when I had just on ontology, but now, when I click on the <code>hasFeature</code> property and then click add annotation, i can't see the <code>hasSimilarityValue</code> there, this is why I see:</p>
