Please review slides 31-34 in [1] for a precise example of the  
technique I am referring to. There is a link to working code that  
implements the example within lsw [2]

In particular note that (restriction !getMethod (has-value ! 
vitaminSourceDemoMethod)))) on vitaminSourceDemoThing means that when  
we ask for the  getMethod of http://www.example.org/NM_013987_XML  
which is a vitaminSourceDemoThing, we get vitaminSourceDemoMethod  
even though it is not explicitly asserted as a property value of  
ex:NM_013987_XML

Since there is an existing worked out example, it would be easier to  
answer questions that refer to it. I found it a little difficult to  
see what you were getting at in your question.

ps. If they are carrots, then they are NotAnInformationEntity, and  
can't be "resolved" at all :)
