Hi,

I'm running Joseki+Pellet. I want the properties and corresponding values of
a Class to be inherited down its subclasses.

So for instance, with the code below, I want <urn:ITEM:1234:REV-1> to
inherit the value of myitem:title from its parent.. So after inference
<urn:ITEM:1234:REV-1> returns the myitem:title value of "Original Name".

Please can someone show me how I should write this in Triples, as what I
have below does not give me a title value for <urn:ITEM:1234:REV-1>after
reasoning by Pellet.. Any help or guidance will be highly valued!
