Signaling Devicec back to ToC or Class ToC

IRI: https://w3id.org/mep#Signal

A signal is an active device that conveys information or instructions to users, by means of an audio, visual signal or a combination of both. The primary distinction from an Sign is that a signal is active and therefore a subtype of Flow Terminal usually requiring power and data connections for its operation. An instance of Signal represents a singular signalling device in a larger assembled unit or connected system, such as an individual frame within a railway signal, a single light unit in a traffic light system or an audio signal or light mounted on a navigational buoy. Signals can be physically aggregated together into an assembly which can include multiple signal instances (and also sign instances) and the associated supporting structural elements such as a simple pole or a rigid frame gantry (see Signal Assembly for examples). Signals can be logically (functionally) grouped together into a signalling system (a type of distribution system) to represent a connected group of signals for example a group of traffic lights controlling an road intersection.

Waste Terminalc back to ToC or Class ToC

IRI: https://w3id.org/mep#WasteTerminal

A waste terminal has the purpose of collecting or intercepting waste from one or more sanitary terminals or other fluid waste generating equipment and discharging it into a single waste/drainage system. A waste terminal provides for all forms of trap and waste point that collects discharge from a sanitary terminal and discharges it into a waste/drainage subsystem or that collects waste from several terminals and passes it into a single waste/drainage subsystem. This includes the P and S traps from soil sanitary terminals, sinks, and basins as well as floor wastes and gully traps that provide collection points.
