adding several values to the same predicate == Bag??

Hi all,

This is a very very simple question... but I am trying to interiorize
myself with containers...

having:

graphA =
<rdf:Description
 rdf:about="http://www.recshop.fake/cd/Beatles">
 <cd:artist>John</cd:artist>
</rdf:Description>


graphB =
<rdf:Description
 rdf:about="http://www.recshop.fake/cd/Beatles">
 <cd:artist>Paul</cd:artist>
</rdf:Description>


graphC =
<rdf:Description
 rdf:about="http://www.recshop.fake/cd/Beatles">
 <cd:artist>
   <rdf:Bag>
     <rdf:li>John</rdf:li>
     <rdf:li>Paul</rdf:li>
   </rdf:Bag>
  </cd:artist>
</rdf:Description>


does the following hold true?

graphA U graphB = graphC


Can anyone point to advanced material on containers and collections??

Thanks,
Aldo
