| PathManager | class | While building a render engine, this Strategy class decides on the actual render strategy in accordance to the current controller settings (system state) |
| pathmanager | artifact | Manager for deciding the actual render strategy |
| Pipe | class | structural asset representing a basic building block within the high level model: a port for building a processing chain and generating media output |
| pipe | artifact | structural asset corresponding to some port generating media output |
| pipes | relation | the global ports (busses) of the session |
| placement | artifact | Key Abstraction: a way to place and locate a Media Object |
