Figure 4

Examples of events published on the SCB. This instantiation diagram visualizes two examples of events that are published on the SCB, namely A) an event indicating that a light sensor with ID L101 measured a light intensity of 100 lumen and B) an event expressing that a person with ID AB452487 is located in room 101. The squares represent classes from the core ontologies. The dashed arrows depict subclass relationships. The blue arrows represent relationships between classes (object properties). The green text and arrows indicate instances of classes, ranges of datatype properties and instantiated object properties.
