Yes, RDF123 supports this example and much more complicated ones.
Earlier spreadsheet to RDF systems generally made the assumption
that each row corresponded to an instance and specified values for
its properties. In RDF123, each row can create any number of
instances. Take a look at the examples in http://rdf123.umbc.edu/examples/
