Description
RDF defines several container elements.
The rdf:Bag element groups together relevant resources.
The order of resources is not important and it can contain duplicate
resources. The individual resources are either individually numbered with rdf:_1, rdf:_2, rdf:_3 ... , or generalized form
rdf:li can be used.
