Description The Smart Appliances REFerence (SAREF) ontology is a shared model of consensus that facilitates the matching of existing assets (standards/protocols/datamodels/etc.) in the smart appliances domain. The SAREF ontology provides building blocks that allow separation and recombination of different parts of the ontology depending on specific needs. @en

Comment
(2016-06-15) Ghislain Atemezing: A reference ontology for smart appliances developed with the support of the European Commission. SAREF provides modular building blocks to represent devices in the smart home environment, such as lists of functions, commands and states that can be combined to create complex functionality in a single device.
(2019-06-27) María Poveda-Villalón: Information about changes compared to version 1.1.1: • The classes and properties related to how to represent devices in building spaces (such as the saref:BuildingSpace class, saref:BuildingObject class and saref:isLocatedIn property) have been removed from SAREF and incorporated into the SAREF4BLDG extension related to buildings [i.4], including the reuse of the W3C® WGS84 geo positioning vocabulary. • The saref:DeviceCategory and saref:FunctionCategory classes have been removed. Instead, the hierarchy of device categories has been implemented directly as subclasses of the saref:Device class. • The information specific for energy efficiency has been moved to the SAREF4ENER extension. For example, the saref:Profile class has been redefined to accommodate only the properties that are general enough for any type of profile, not only for energy and power. Details on how to specifically model a power profile can be found in the SAREF4ENER extension [i.2]. • The subclasses of the saref:Energy class have been removed (i.e., Average Energy, Maximum Energy, Minimum Energy, Total Energy, HVAC Energy, Hot Water Energy and Lighting Energy). • The saref:Property class has been split into two classes (saref:Property and saref:Measurement), as it is done in the SAREF4ENVI extension in [i.3], in order to properly accommodate the distinction between the concept of property (an observable quality of something) and the concept of measurement (a concrete value observed for a property). • Too restrictive cardinality restrictions have been revised, sometimes making them optional rather than mandatory (better to make properties mandatory in the extensions that specialize SAREF for a specific purpose, rather than restricting SAREF, whose purpose is more general). For example, definitions of units of measurement using an enumeration (owl:oneOf) were too restrictive because they did not allow using other units than those enumerated. Therefore, the individuals of each class are still there, but the owl:oneOf enumeration has been removed. • The saref:UnitOfMeasure subclassesre use individuals from the OM ontology for unit of measures (http://www.wurvoc.org/vocabularies/om-1.6/), but this is not the only solution. It has been clarified in the comments that the OM ontology is an example, but other ontologies can be used. • The global restrictions (rdfs:domain and rdfs:range) in object properties have been completely removed not to hinder interoperability. Object properties are now only restricted locally in the classes. • The subclasses of saref:Task have been transormed in individuals. • The saref:hasTask property has been removed from the saref:Profile class to resolve an ambiguity with the saref:Task class.
(2020-03-10) Ghislain Atemezing: New URI namespace now under ETSI at https://saref.etsi.org/core/. We might need to change the URI in LOV.
(2021-02-25) María Poveda-Villalón: Updated to new namespace
