Re: Individuals with more than one rdf:type

As a general rule of thumb, mentally replace, in everything you read,

 "rdf:type" with "is a member of the set",
 "rdfs:subClassOf" with "is a subset of",
 and the name of every class with "named XXX".

That will convey the correct semantics.

... the instance named "MacBookPro" is a member of the set named  
Laptop, the set named MacintoshComputer, and the set named i386Computer.

RDF types are not object oriented classes. RDF instances are not  
objects. They do not inherit anything in the OO sense.
