Resource Description Framework (RDF) - slide "Statements about the elements of a container"

One could also say:

  <rdf:Bag ID="pages">
    <rdf:li resource="http://foo.org/foo.html" />
    <rdf:li resource="http://bar.org/bar.html" />
  </rdf:Bag>
  
  <rdf:Description about="#pages">
    <s:creator>Bob Hopgood</s:creator>
  </rdf:Description>

This is a statement on the Bag as a whole. But:

  
  <rdf:Description aboutEach="#pages">
    <s:creator>Bob Hopgood</s:creator>
  </rdf:Description>

expresses a statement about each element of the container.
