The extension was create
27、d in collaboration with domain experts in the field of light pollution currently working in the STARS4ALL European H2020 project (http:/www.stars4all.eu/index.php/lpi/). The STARS4ALL project is composed by partners such as Universidad Politcnica de Madrid, Universidad Complutense de Madrid, ESCP Eu
28、rope, Leibniz Institute of Freshwater Ecology and Inland Fisheries, Instituto de Astrofsica de Canarias, University of Southampton, Europan Crowdfunding Network, and CEFRIEL (Societ Consortile a Responsabilita Limitata). SAREF4ENVI has two main aims: on the one hand, to be the basis for enabling the
29、 use of SAREF in the environment domain and, on the other hand, to exemplify how to enable interoperability between environmental devices in cooperation. SAREF4ENVI is an OWL-DL ontology that extends SAREF with 32 classes (24 defined in SAREF4ENVI and 7 reused from the time, SAREF and geo ontologies
30、), 24 object properties (22 defined in SAREF4ENVI and 2 reused from the SAREF and geo ontologies), 13 data type properties (9 defined in SAREF4ENVI and 4 reused from the SAREF ontology), and 24 individuals (9 defined in SAREF4ENVI and 12 reused from the OM ontology). SAREF4ENVI focuses on extending
31、SAREF for photometers to solve the lack of interoperability between sensors that can measure and share information about light pollution. Such extension involves the following use cases (more details can be found in ETSI TR 103 411 i.1): Use case 1: Monitor light pollution in a city, through the dat
32、a collected by photometers about the magnitude of the light emitted in a given area. Use case 2: Adjust lampposts light intensity due to high pollution, after identifying the most contaminating lampposts and therefore the areas where more energy is being thrown away. Use case 3: Register a photomete
33、r, in which a new collection of photometers is incorporated into an existing sensor network. The prefixes and namespaces used in SAREF4ENVI and along this document are listed in Table 1.

35、 xsd http:/www.w3.org/2001/XMLSchema# 4.2 SAREF4ENVI 4.2.1 General overview A graphical overview of the SAREF4ENVI ontology is provided in Figure 1. In such figure, grey rectangles are used to denote classes created in the ontology while white rectangles denote reused classes. For all the entities,
36、it is indicated whether they are defined in the extension or in other ontologies by the prefix included before their identifier, that is, if the element is defined in SAREF4ENVI there is no prefix added and if the element is reused from another ontology it is indicated by a prefix according to Table
37、 1. Arrows are used represent properties between classes and to represent some RDF, RDF-S and OWL constructs, more precisely: Plain arrows with white triangles represent the rdfs:subClassOf relation between two classes. The origin of the arrow is the class to be declared as subclass of the class at
38、the destination of the arrow. Dashed arrows between two classes indicate a local restriction in the origin class, i.e. that the object property can be instantiated between the classes in the origin and the destination of the arrow. The identifier of the object property is indicated within the arrow.
39、 Dashed arrows with identifiers between stereotype signs (i.e. “) refer to OWL constructs that are applied to some ontology elements, that is, they can be applied to classes or properties depending on the OWL construct being used. Dashed arrows with no identifier are used to represent the rdf:type r
40、elation, indicating that the element in the origin of the arrow is an instance of the class in the destination of the arrow. Datatype properties are denoted by rectangles attached to the classes, in an UML-oriented way. Dashed boxes represent local restrictions in the class, i.e. datatype properties
41、 that can be applied to the class it is attached to. Individuals are denoted by grey rectangles (or white ones in the case of being reused from other ontologies) in which the identifier is underlined. The representation of additional property axioms (functional, inverse functional, transitive, and s
42、ymmetric) that are being used in the diagram is shown in the legend of Figure 1. Clause 4.2.2 to clause 4.2.7 describe the different parts of the SAREF4ENVI extension describing the different conceptual modules of the ontology.

43、.2.2 Physical Object Hierarchy In SAREF4ENVI, the SAREF ontology has been extended with various elements to describe different physical objects, devices, and their characteristics. Apart from extending the saref:Device class with the s4envi:Device class, a hierarchy has been defined also including t
44、he classes s4envi:PhysicalObject, s4envi:System and s4envi:Actuator in the upper levels. In order to represent sensors from the light pollution domain, the classes s4envi:Photometer and s4envi:TESS (a specific type of photometer) have been included extending the hierarchy. Such classes are organized
45、 in the hierarchy shown in Figure 2. ETSI ETSI TS 103 410-2 V1.1.1 (2017-01)9 Figure 2: Physical Object hierarchy 4.2.3 Devices and Measurements Devices and measurements are depicted in Figure 3. This model represents an n-ary pattern that allows users to relate different measurements from a given s
46、ensor for different properties measured in different units. That is, the saref:Measurement class aims at describing a measurement of a physical quantity (using the saref:hasValue property) for a given saref:Property and according to a given saref:UnitOfMeasure. This pattern enables to differentiate
47、between properties and the measurements made for such properties and to store measurements for a concrete property in different units of measurement. Furthermore, it allows adding a timestamp (using the saref:hasTimeStamp property) to identify when the measurement applies to the property, which can
48、be used either for single measurements or for series of measurements (e.g. measurement streams). It is worth noting that this modelling was included in SAREF 2.0 after the SAREF4ENVI extension was developed. This pattern was first included in the SAREF4ENVI and SAREF4BLDG extensions and then propose
49、d to be extrapolated to SAREF 2.0; this explains why the prefix used for this part of the model refers to SAREF instead of to SAREF4ENVI. However, as its origin is in the SAREF4ENVI and SAREF4BLDG extensions requirements and models, the explanations are kept in the present document.
