SAREF reference ontology patterns
The SAREF reference ontology patterns provide guidelines on how to use and extend SAREF concepts and relationships for the modelling and the description of any kind of applications-related data/information/systems. The SAREF reference ontology patterns can be applied to different verticals to provide the SAREF suite of ontologies a homogeneous and predictable structure, and to achieve higher semantic interoperability.
SAREF4SYST patterns for connection points of systems
Sub-classes of s4syst:ConnectionPoint
A specialization of the SAREF4SYST pattern may define a sub-class of the s4syst:ConnectionPoint class. If defined, it shall have an English-tagged label (rdfs:label) ending with "Connection Point". The local name of its IRI shall be a camel case form of its English-tagged label.
EXAMPLE 1: ex:ThreePhaseConnectionPoint has English-tagged label "Three-Phase Connection Point"@en.
A sub-class of the s4syst:ConnectionPoint class shall have an English-tagged comment (rdfs:comment) that defines it in natural language.
EXAMPLE 2: ex:ThreePhaseConnectionPoint has English-tagged comment "A three-phase connection point is a connection point composed of four wires (plus the protective earth): wires R, S, T, for the phases; wire N for the neutral".@en.
A sub-class of the s4syst:ConnectionPoint class may have a universal restriction on the property s4syst:connectsSystemThrough or one of its sub-properties to a sub-class of s4syst:Connection. If so, then the label or the comment of the sub-class of s4syst:ConnectionPoint and the sub-class of s4syst:Connection shall show this relation ostensibly.
A sub-class of the s4syst:ConnectionPoint class may have a universal restriction on the property s4syst:connectionPointOf to a sub-class of s4syst:System. If so, then the label or the comment of the sub-class of s4syst:ConnectionPoint and the sub-class of s4syst:System shall show this relation ostensibly.
EXAMPLE 3: ex:IlluminableZoneFrontierConnectionPoint has a universal restriction on the property s4syst:connectsSystemThrough to the class ex:LightTransmissionSystemConnection, has a universal restriction on the property s4syst:connectionPointOf to the class s4syst ex:IlluminableZoneSystem, and has English-tagged comment "The class of zones frontiers _on_ which one may measure/effect luminosity, and perceive brightness. Illuminable zones are surfaces such as walls, tables, sheer curtains, mirrors, windows. Light may be reflected, absorbed, and transmitted by illuminable zone frontier connection points"@en.
Sub-properties of s4syst:connectionPointOf
A specialization of the SAREF4SYST pattern may define a sub-property of the s4syst:connectionPointOf property. If defined, it shall have an English-tagged label (rdfs:label), and the local name of its IRI shall be a mixed case form of its English-tagged label. The label of the sub-property should use the same morpho-syntactic structure as its super-property.
A sub-property of the s4syst:connectionPointOf property shall have an English-tagged comment (rdfs:comment) that describes in natural language how the connected s4syst:System interact.
Sub-properties of s4syst:connectsAt
A specialization of the SAREF4SYST pattern may define a sub-property of the s4syst:connectsAt property. If defined, it shall have an English-tagged label (rdfs:label), and the local name of its IRI shall be a mixed case form of its English-tagged label. The label of the sub-property should use the same morpho-syntactic structure as its super-property.
EXAMPLE 1: ex:connectsPrimarilyAt has English-tagged label "connects primarily at"@en.
A sub-property of the s4syst:connectsAt property shall have an English-tagged comment (rdfs:comment) that describes in natural language how the connected s4syst:System interact.
EXAMPLE 2: ex:connectsPrimarilyAt has English-tagged comment "Links an electric power transformer system to its primary connection point"@en.
A sub-class of s4syst:System may be equivalent to an anonymous class having a universal restriction on s4syst:connectsAt or one of its sub-properties to a sub-class of s4syst:ConnectionPoint. If so, then the label or the comment of the sub-class of s4syst:System and the sub-class of s4syst:ConnectionPoint shall show this relation ostensibly.
EXAMPLE 3: ex:USBCommunicationDeviceSystem is equivalent to an anonymous class having a universal restriction on s4syst:connectsAt to the class ex:USBCommunicationConnectionPoint, and has English-tagged comment "The class of communication devices capable of communicating using the USB protocol"@en.
Sub-properties of s4syst:connectsSystemThrough
A specialization of the SAREF4SYST pattern may define a sub-property of the s4syst:connectsSystemThrough property. If defined, it shall have an English-tagged label (rdfs:label), and the local name of its IRI shall be a mixed case form of its English-tagged label. The label of the sub-property should use the same morpho-syntactic structure as its super-property.
EXAMPLE 1: ex:connectsSystemInSNThrough has English-tagged label "connects system in SN through"@en.
A sub-property of the s4syst:connectsSystemThrough property shall have an English-tagged comment (rdfs:comment) that describes in natural language how the connected s4syst:System interact.
EXAMPLE 2: ex:connectsSystemInSNThrough has English-tagged comment "Links a single phase connection point to a three-phase power bus connection with which it is connected with a SN configuration"@en A sub-property of the s4syst:connectsSystemThrough property may have an inverse property. If defined, the English-tagged labels and comments of these two properties shall reflect this aspect.
EXAMPLE 3: ex:connectsSystemInSNThrough and ex:connectsSystemInSNAt are inverse properties.
A sub-property of the s4syst:connectsSystemThrough property may be defined as disjoint from other sub-properties of s4syst:connectsSystemThrough.
EXAMPLE 4: The following properties are disjoint: ex:connectsSystemInStarThrough and ex:connectsSystemInTriangleThrough.
Sub-properties of s4syst:connectsSystemAt
A specialization of the SAREF4SYST pattern may define a sub-property of the s4syst:connectsSystemAt property. If defined, it shall have an English-tagged label (rdfs:label), and the local name of its IRI shall be a mixed case form of its English-tagged label. The label of the sub-property should use the same morpho-syntactic structure as its super-property.
EXAMPLE 1: ex:connectsSystemInStarAt has English-tagged label "connects system in star at"@en.
A sub-property of the s4syst:connectsSystemAt property shall have an English-tagged comment (rdfs:comment) that describes in natural language how the connected s4syst:System interact.
EXAMPLE 2: ex:connectsSystemInStarAt has English-tagged comment "Links a three-phase power bus connection to one of the three-phase connection points it connects with a triangle configuration"@en.
A sub-class of s4syst:Connection may have an existential or universal restriction on s4syst:connectsSystemAt or one of its sub-properties to a sub-class of s4syst:ConnectionPoint. If so, then the label or the comment of the sub-class of s4syst:Connection and the sub-class of s4syst:ConnectionPoint shall show this relation ostensibly.
EXAMPLE 3: ex:USBCommunicationConnection has a universal restriction on s4syst:connectsSystemAt to the class ex:USBCommunicationConnectionPoint, and has English-tagged comment "The class of USB communication connections between communication devices"@en.
A sub-property of the s4syst:connectsSystemAt property may have an inverse property. If defined, the English-tagged labels and comments of these two properties shall reflect this aspect.
EXAMPLE 4: ex:connectsSystemInSNAt and ex:connectsSystemInSNThrough are inverse properties.
A sub-property of the s4syst:connectsSystemAt property may be defined as disjoint from other sub-properties of s4syst:connectsSystemThrough.
EXAMPLE 5: The following properties are disjoint: ex:connectsSystemInStarAt and ex:connectsSystemInTriangleAt.
