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.

Granularity of the profile (e.g., weekly, daily)
Reliability associated to a virtual node
A specification associated to a Virtual Node or a device to collect information about properties
A relationship defining the value of a certain property, e.g., energy or power. Note that, even if numeric values are expected to enable reasoning, measurement values could use other datatypes.
A relationship between a measurement and the feature of interest whose quality was measured
Relationship between a violation and its type, which can be overvoltage, undervoltage or overloading.
Relationship between an event and its duration

Relationship between an action and the virtual node in charge of perform it
A relationship specifying the property that can be measured by a certain device
Constraints of the grid that limits a system
link between the Virtual node and its smart contracts
An intelligent device, responsible for collecting information stemming from the field devices (home appliances, distributed energy resources, storage components etc.) to the DELTA Virtual Nodes and facilitate end-to-end communication of signals from/to the Aggregator and to/from the field devices. 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.
Relation between a smart contract and the payment associated
Relationship between a violation and a profile that describes such violation
A temporal entity with an extent or duration
A property related to measurements that are characterized by a value measured in energy units
Aggrupation of elements, such as FEIDs or Virtual Nodes
Value that indicates whether the FEID is available
Relation between a Virutal Node and the devices it manages
Frequency constraint related to the grid
Element contained in the FEID that detects and responds to events in an environment
A relationship identifying what an entity, such as a Profile, is about
Link between a Virtual Node and its index
Relation to define the comfort settings of a system
A temporal entity with zero extent or duration
Incentive (usually monetary) associated to energy values
Relationship between a smart contract and the property it agrees on
Reward associated to the customers that is given after using the engagement tools
Reward associated to the customers that is given after using the engagement tools (e.g., discounts)
Relationship between the FEID and the violation it detects
Reliability and Fairness Index that refers to the distribution network configuration
Link between the customers and the devices
A saref:Property crelated to some measurements that are characterized by a certain value that is measured using saref:Currency
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.
DR type that is implemented by the FEID, which can be implicit or explicit
Points that are used by the DELTA platform to calculate the customers rewards
A relation between a property and its incentives associated
Relation between a virtual node and its associated aggregator
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.
A spatial representation for a given feature.
A feature of interest represents any real world entity from which a property is measured.
Address of the service within the system.
A relationship between a property and the measurements it relates to
Relation between an object and the geographical feature in which it is located at
A property related to measurements that are characterized by a value measured in power units
Relationship between a DR request and the needed measurement in order to solve a violation
Relation between an aggregator and the market settlement it consumes
A relationship indicating a composite entity that consists of other entities (e.g., a temperature/humidity sensor that consists of a temperature sensor and a humidity sensor)
The final status as if the DVN fullfiled the request or it failed
A relationship stating the timestamp of an entity (e.g. a measurement).
Period where an entity, such a contract, is valid
Link between a smart contracts and the transactions it stores
Transaction between entities that will be store in the smart contract
Link to the grid constraints of a system
Legal entities that aggregate the load or generation of various demand and/or generation/production units and aim at optimizing energy supply and consumption.
Link from a virtual node to its aggregator
A relationship between a measurement and the property it relates to
This class represents the top-level feature type. This class is equivalent to GFI_Feature defined in ISO 19156:2011, and it is superclass of all feature types.
Link between a customer and its associated reward
The class represents the top-level geometry type. This class is equivalent to the UML class GM_Object defined in ISO 19107, and it is superclass of all geometry types.
A link between a node and the event it sends
Relationship identifying the properties associated to a group of entities, such as clusters
The unit of measure is a standard for measurement of a quantity, such as a Property. 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).
