observed property^op back to ToC or Object Property ToC

IRI: http://purl.oclc.org/NET/ssnx/ssn#observedProperty

is defined by: http://purl.oclc.org/NET/ssnx/ssn

Relation linking an Observation to the Property that was observed. The observedProperty should be a Property (hasProperty) of the FeatureOfInterest (linked by featureOfInterest) of this observation.

observes^op back to ToC or Object Property ToC

IRI: http://purl.oclc.org/NET/ssnx/ssn#observes

is defined by: http://purl.oclc.org/NET/ssnx/ssn

Relation between a Sensor and a Property that the sensor can observe. Note that, given the DUL modelling of Qualities, a sensor defined with 'observes only Windspeed' technically links the sensor to particular instances of Windspeed, not to the concept itself - OWL can't express concept-concept relations, only individual-individual. The property composition ensures that if an observation is made of a particular quality then one can infer that the sensor observes that quality.

of feature^op back to ToC or Object Property ToC

IRI: http://purl.oclc.org/NET/ssnx/ssn#ofFeature

is defined by: http://purl.oclc.org/NET/ssnx/ssn

A relation between some aspect of a sensing entity and a feature. For example, from a sensor to the features it can observe properties of, or from a deployment to the features it was installed to observe. Also from a measurement capability to the feature the capability is described for. (Used in conjunction with forProperty).

on platform^op back to ToC or Object Property ToC

IRI: http://purl.oclc.org/NET/ssnx/ssn#onPlatform

is defined by: http://purl.oclc.org/NET/ssnx/ssn

Relation between a System (e.g., a Sensor) and a Platform. The relation locates the sensor relative to other described entities entities: i.e., the Sensor s1's location is Platform p1. More precise locations for sensors in space (relative to other entities, where attached to another entity, or in 3D space) are made using DOLCE's Regions (SpaceRegion).

quality of observation^op back to ToC or Object Property ToC

IRI: http://purl.oclc.org/NET/ssnx/ssn#qualityOfObservation

is defined by: http://purl.oclc.org/NET/ssnx/ssn

Relation linking an Observation to the adjudged quality of the result. This is of course complimentary to the MeasurementCapability information recorded for the Sensor that made the Observation.

sensing method used^op back to ToC or Object Property ToC

IRI: http://purl.oclc.org/NET/ssnx/ssn#sensingMethodUsed

is defined by: http://purl.oclc.org/NET/ssnx/ssn

A (measurement) procedure is a detailed description of a measurement according to one or more measurement principles and to a given measurement method, based on a measurement model and including any calculation to obtain a measurement result [VIM 2.6]
