A Sequence or Seq (a resource having type
rdf:Seq) represents a group of
resources or literals, possibly including duplicate members, where the order of
the members is significant.
EXAMPLE: A Sequence might be used to describe a group that must be maintained in alphabetical order.

To describe a resource as being a Sequence, the resource
is given an rdf:type property whose value is rdf:Seq
The rdf:Seq class is the class of RDF 'Sequence' containers. It
is a subclass of rdfs:Container. Whilst formally it is no
different from an rdf:Bag or an rdf:Alt, the rdf:Seq class is used
conventionally to indicate to a human reader that the numerical ordering of the
container membership properties of
the container is intended to be significant.
