subclass of: Restriction
  on property: has cluster
  all values from: Cluster
subclass of: Restriction
  on property: has profile
  all values from: Profile
subclass of: Restriction
  on property: manage
  all values from: Device
comment: An aggregated, virtual cluster of prosumers which will be perceived and acted upon as a single, large prosumer entity by the Aggregator. Prosumers entailed into each Virtual Node will have common characteristics, defined by their corresponding Aggregator.

Device
type: Class
equivalent class: Restriction
  on property: measuresProperty
  all values from: Property
comment: A tangible object designed to accomplish a particular task in households, common public buildings or offices. In order to accomplish this task, the device performs one or more functions. For example, a washing machine is designed to wash (task) and to accomplish this task it performs a start and stop function. Devices can be structured in categories (subclasses) that reflect the different domain in which a device is used, e.g., smart appliances domain (subclass FunctionRelated) vs. building domain (subclass BuildingRelated) vs. smart grid domain (subclass EnergyRelated). New categories can be defined,if needed, to reflect other differences, for example different points of view, such as the point of view of the device's user vs. the point of view of the device's manufacturer. We propose a list of devices that are relevant for the purpose of SAREF, but this list can be extended.
