The FTOnto enables reseachers to sematically describe a physical fischertechnik factory simulation environment. This is archieved by aligning concepts from MASON and SOSA with own concepts. Furthermore the FTOnto can capture knowledge about semantic web services which are used to interact between the service-layer and the cyber-physical layer in a cyber-physical production system. This includes precondition which have to be met before a webservice can be performed, postconditions which check if the webservice execution was performed successfully and effects which describe the changed state of the domain after performing a service.
