The flexibility ontology module (ic-flex) is by design tightly integrated with SAREF, SAREF4ENER and the following InterConnect modules: power limit (ic-pwlm), incentive table (ic-inc), S2 (ic-s2), data-point (ic-data) and forecast (ic-fc) The main concept of the ic-flex module is the s4ener:FlexOffer, which allows to represent a flexibility offer (or schedule) as a combination of multiple time-series, data-points and forecasts. It also allows to specify a creation time (s4ener:hasCreationTime), validity period (s4ener:hasEffectivePeriod) and provenance (s4ener:producedBy) for the offer, on top of the creation time, validity period and provenance already specified for the time-series and data-points included in the offer. The additional key aspect captured in the ic-flex module is that a flex offer can also include various categories of flexibility, which are modelled as subclasses of the s4ener:FlexibilityProfile class, as follows: - Power Profile flexibilty is modelled as s4ener:PowerProfile based on the EEBUS spec - Tariff based flexibility (s4ener:TariffBased) is implemented using the incentive table (ic-inc) ontology based on the EEBUS spec (note that tariif-based felxibility does note exist in S2) - Power limit flexibility (ic-pwlm:PowerLimit) is implemented using thepower limit (ic-pwlm) ontology based on the EEBUS spec (and compliant also with S2) - Power Envelope flexibility (s4ener:PowerEnvelope) is implemented using theS2 (ic-s2) that follows the S2 specification (and compliant also with EEBUS) - Demand driven flexibility (s4ener:DemandDriven) flexibility (s4ener:PowerEnvelope) is implemented using theS2 (ic-s2) that follows the S2 specification (and compliant also with EEBUS) - Operation mode flexibility (s4ener:OperationMode) is implemented using theS2 (ic-s2) that follows the S2 specification (and compliant also with S2) - Fill rate based flexibility (s4ener:FillRateBased is implemented using theS2 (ic-s2) that follows the S2 specification (and compliant also with S2)

Independent from the ActuatorSwitch class, the ActuatorLevel class enables a user or application to model LEVEL commands (start, up, percentageAbsolute, relative, etc.). This can be used to dim a light, set the speed of an electric motor, etc.
Actuator level
Basic on/off operations on a simple actuator can be modelled with the ActuatorSwitch class. Whether the function turns a device itself ON or OFF, or whether it switches a specific feature, depends on the implementation. For example, one could model the super freeze program of a freezer using ActuatorSwitch class. An ON command would then activate the super freeze program and an OFF command would deactivate it. This example shall just give an idea how ActuatorSwitch can be used for more purposes than only turning devices on and off.

An Instruction as specified for an Demand Driven Based Control Profile.
Demand Driven Based Control Instruction
A data point is a quantity that is extended with various pieces of process information, namely - A creation time (instant). This is the point in time when the data point was created, which is not necessarily the time for which it is valid. In the case of soft-sensors or forecasters, a data point might have been created ahead of time, in the case of a direct observation a data point might created at its time of validity (or at the end of its validity time interval) and in the case of an archived value the data point might have been created after the fact. - A validity time (temporal entity) which will be named "time stamp". The validity time is the instant or interval in time in which a specific quantity is in effect. For example a room temperature might be measured at 12:00, which means it is in effect at this very instant. A specific amount of energy might me expended within the time-slot between 12:30 and 12:45, which means that the energy observation is in effect during this time interval. - A location or topological association. For example, an observation might be taken in a specific room, a power avarage might have been measured by a specific meter, a forecast might be valid for a specific region or grid segment. This association is therefore not always a location.

A specialization of a saref:Device that exposes a power profile with power sequences to the CEM. Most of the existing devices can expose at most one power profile, but there are special cases in which more than one power profiles can be exposed by the same device. For example, consider the case of a combined fridge-freezer in which there are 2 logical devices (fridge and freezer) combined in 1 physical device. This combined device can expose 2 power profiles, one for the fridge and one for the freezer. A s4ee:Device (e.g. a household appliance or a smart meter) can also receive events about overload warning severity level and related load control commands (LoadControlEventData)
