        "http://www.w3.org/2000/01/rdf-schema#comment" : [ "In mathematics, the Klein bottle /ˈklaɪn/ is an example of a non-orientable surface; it is a two-dimensional manifold against which a system for determining a normal vector cannot be consistently defined.  Informally, it is a one-sided surface which, if traveled upon, could be followed back to the point of origin while flipping the traveler upside down.  Other related non-orientable objects include the Möbius strip and the real projective plane." ] ,
