description description https://saref.etsi.org/core/ Profile A specification associated to a device to collect information about a certain Property (e.g., Energy) or Commodity (e.g.Water) for optimizing its usage in the home, office or building in which the device is located. This specification is about a certain Property or Commodity (saref:isAbout), can be calculated over a time span (saref:hasTime ) and can be associated to some costs (saref:hasPrice). An example is the Power Profile defined in the SAREF4ENER extension that can be associated to a device for optimizing the Energy efficiency in the home, office or building in which the device is located.

FEIDs will be equipped with smart meters measuring energy related data (e.g. consumption, generation, emissions, power coefficient, etc.) and through an intelligent lightweight toolkit compute real-time flexibility, providing them as input to the DVN Agent using fog computing techniques, aligned to a strategy (i.e. time interval) imposed to the specific Node by the Aggregator.

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.

For example, Power is a property and Watt is a unit of power that represents a definite predetermined power: when we say 10 Watt, we actually mean 10 times the definite predetermined power called \"watt\". Our definition is based on the definition of unit of measure in the Ontology of units of Measure (OM). We propose here a list of some units of measure that are relevant for the purpose of SAREF, but this list can be extended, also using some other ontologies rather than the Ontology of units of Measure (OM).
