Core Concepts and Functionality
Orion Context Broker operates based on entities, attributes, and subscriptions. These elements enable interaction between context producers and consumers.
Entities
Entities represent objects in the system and have properties called attributes. For example, a sensor monitoring room temperature can be an entity, and the temperature reading is its attribute.
Each entity is identified by:
-
ID: Unique identifier for the entity.
-
Type: Defines what kind of object the entity represents (e.g., "Sensor", "Room").
