modeling nested containers with items

I'm having a hard time figuring out an RDF way to model containers that can
each contain items and/or other containers. A filesystem directory/file
structure and a bookmark folder/bookmark structure are good examples.
Assuming that each container and each item can have properties (e.g.
"created" in the example below), how could I represent the following in RDF?
My attempts at using RDF containers have been bumping into those striping
issues. Or is even attempting to use RDF here a case of barking up the wrong
tree? 


   <container id="i1" created="20031001">
      <item id="i2" created="20031001"/>         
      <item id="i3" created="20031003"/>         
      <container id="i4" created="20031002">
         <item id="i5" created="20031002"/>          
         <item id="i6" created="20031003"/>          
         <item id="i7" created="20031001"/>          
         <container id="i8" created="20031003">
            <item id="i9" created="20031004"/>
         </container>
         <container id="i10" 20031004"/>
      </container>
   </container>

thanks,

Bob
