Description
This ontology describes sensors and observations, and related concepts. It does not describe domain concepts, time, locations, etc. these are intended to be included from other ontologies via OWL imports.
This ontology is developed by the W3C Semantic Sensor Networks Incubator Group (SSN-XG). The concepts and structure of the ontology were discussed in the group's meetings and on the mailing list. For more information on the group's activities see: http://www.w3.org/2005/Incubator/ssn/
Please report any errors to the Semantic Sensor Network Incubator Activity via the public W3C list public-xg-ssn@w3.org

Section Skeleton

Introduction Skeleton

This part of the ontology defines 8 classes and 13 properties .

Module Term Name Type Definition
Skeleton FeatureOfInterest class A feature is an abstraction of real world phenomena (thing, person, event, etc).
Skeleton Observation class An Observation is a Situation in which a Sensing method has been used to estimate or calculate a value of a Property of a FeatureOfInterest. Links to Sensing and Sensor describe what made the Observation and how; links to Property and Feature detail what was sensed; the result is the output of a Sensor; other metadata details times etc.
Skeleton Property class An observable Quality of an Event or Object. That is, not a quality of an abstract entity as is also allowed by DUL's Quality, but rather an aspect of an entity that is intrinsic to and cannot exist without the entity and is observable by a sensor.
Skeleton Sensing class Sensing is a process that results in the estimation, or calculation, of the value of a phenomenon.
Skeleton Sensor class A sensor can do (implements) sensing: that is, a sensor is any entity that can follow a sensing method and thus observe some Property of a FeatureOfInterest. Sensors may be physical devices, computational methods, a laboratory setup with a person following a method, or any other thing that can follow a Sensing Method to observe a Property.
Skeleton SensorInput class An Event in the real world that 'triggers' the sensor. The properties associated to the stimulus may be different to eventual observed property. It is the event, not the object that triggers the sensor.
Skeleton SensorOutput class A sensor outputs a piece of information (an observed value), the value itself being represented by an ObservationValue.
Skeleton Stimulus class An Event in the real world that 'triggers' the sensor. The properties associated to the stimulus may be different to eventual observed property. It is the event, not the object that triggers the sensor.
Skeleton detects property A relation from a sensor to the Stimulus that the sensor can detect. The Stimulus itself will be serving as a proxy for (see isProxyOf) some observable property.
Skeleton featureOfInterest property A relation between an observation and the entity whose quality was observed. For example, in an observation of the weight of a person, the feature of interest is the person and the quality is weight.
Skeleton forProperty property A relation between some aspect of a sensing entity and a property. For example, from a sensor to the properties it can observe, or from a deployment to the properties it was installed to observe. Also from a measurement capability to the property the capability is described for. (Used in conjunction with ofFeature).
Skeleton hasProperty property A relation between a FeatureOfInterest and a Property of that feature.
Skeleton implementedBy property A relation between the description of an algorithm, procedure or method and an entity that implements that method in some executable way. For example, between a scientific measuring method and a sensor the senses via that method.
Skeleton implements property A relation between an entity that implements a method in some executable way and the description of an algorithm, procedure or method. For example, between a Sensor and the scientific measuring method that the Sensor uses to observe a Property.
Skeleton isPropertyOf property Relation between a FeatureOfInterest and a Property (a Quality observable by a sensor) of that feature.
Skeleton isProxyFor property A relation from a Stimulus to the Property that the Stimulus is serving as a proxy for. For example, the expansion of the quicksilver is a stimulus that serves as a proxy for temperature, or an increase or decrease in the spinning of cups on a wind sensor is serving as a proxy for wind speed.
Skeleton observationResult property Relation linking an Observation (i.e., a description of the context, the Situation, in which the observatioin was made) and a Result, which contains a value representing the value associated with the observed Property.
Skeleton observedBy property
Skeleton observedProperty property 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.
Skeleton ofFeature property 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).
Skeleton sensingMethodUsed property 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]

Observation

An Observation is a Situation in which a Sensing method has been used to estimate or calculate a value of a Property of a FeatureOfInterest. Links to Sensing and Sensor describe what made the Observation and how; links to Property and Feature detail what was sensed; the result is the output of a Sensor; other metadata details times etc.

Label: Observation
Source: skos:closeMatch 'observation' [O&M] Observation in this ontology and O&M are described differently (O&M records an observation as an act/event), but they record the same thing and are essentially interchangeable. The difference is in the ontological structure of the two, not the data or use. Observation here records a Situation (the estimation of the value of a Property) and a description of the method that was used (along with the participants), while O&M interprets an Observation as the event itself; there must, however, have been an event that lead to our situation, so both are records of events. The distinction is between the event itself and the record of what happened in that event. skos:closeMatch 'measurement result' [VIM 2.9] result in VIM is the measured value plus any other relevant information, which means that measurement result and observation will often be associated to the same data (a value, a time, a property, etc.).

Introduction Sensor

This part of the ontology defines 15 classes and 3 properties .

Module Term Name Type Definition
Measuring SensingDevice class A sensing device is a device that implements sensing.
Measuring SensorDataSheet class A data sheet records properties of a sensor. A data sheet might describe for example the accuracy in various conditions, the power use, the types of connectors that the sensor has, etc. Generally a sensor's properties are recorded directly (with hasMeasurementCapability, for example), but the data sheet can be used for example to record the manufacturers specifications verses observed capabilites, or if more is known than the manufacturer specifies, etc. The data sheet is an information object about the sensor's properties, rather than a direct link to the actual properties themselves.
Measuring observes property 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.
MeasuringCapability Accuracy class The closeness of agreement between the value of an observation and the true value of the observed quality.
MeasuringCapability DetectionLimit class An observed value for which the probability of falsely claiming the absence of a component in a material is β, given a probability α of falsely claiming its presence.
MeasuringCapability Drift class A, continuous or incremental, change in the reported values of observations over time for an unchanging quality.
MeasuringCapability Frequency class The smallest possible time between one observation and the next.
MeasuringCapability Latency class The time between a request for an observation and the sensor providing a result.
MeasuringCapability MeasurementCapability class Collects together measurement properties (accuracy, range, precision, etc) and the environmental conditions in which those properties hold, representing a specification of a sensor's capability in those conditions. The conditions specified here are those that affect the measurement properties, while those in OperatingRange represent the sensor's standard operating conditions, including conditions that don't affect the observations.
MeasuringCapability MeasurementProperty class An identifiable and observable characteristic of a sensor's observations or ability to make observations.
MeasuringCapability MeasurementRange class The set of values that the sensor can return as the result of an observation under the defined conditions with the defined measurement properties. (If no conditions are specified or the conditions do not specify a range for the observed qualities, the measurement range is to be taken as the condition for the observed qualities.)
MeasuringCapability Precision class The closeness of agreement between replicate observations on an unchanged or similar quality value: i.e., a measure of a sensor's ability to consitently reproduce an observation.
MeasuringCapability Resolution class The smallest difference in the value of a quality being observed that would result in perceptably different values of observation results.
MeasuringCapability ResponseTime class The time between a (step) change inthe value of an observed quality and a sensor (possibly with specified error) 'settling' on an observed value.
MeasuringCapability Selectivity class Selectivity is a property of a sensor whereby it provides observed values for one or more qualities such that the values of each quality are independent of other qualities in the phenomenon, body, or substance being investigated.
MeasuringCapability Sensitivity class Sensitivity is the quotient of the change in a result of sensor and the corresponding change in a value of a quality being observed.
MeasuringCapability hasMeasurementCapability property Relation from a Sensor to a MeasurementCapability describing the measurement properties of the sensor.
MeasuringCapability hasMeasurementProperty property Relation from a MeasurementCapability to a MeasurementProperty. For example, to an accuracy (see notes at MeasurementCapability).

Module Term Name Type Definition
Deployment Deployment class The ongoing Process of Entities (for the purposes of this ontology, mainly sensors) deployed for a particular purpose. For example, a particular Sensor deployed on a Platform, or a whole network of Sensors deployed for an observation campaign. The deployment may have sub processes, such as installation, maintenance, addition, and decomissioning and removal.
Deployment DeploymentRelatedProcess class Place to group all the various Processes related to Deployment. For example, as well as Deplyment, installation, maintenance, deployment of further sensors and the like would all be classified under DeploymentRelatedProcess.
Deployment deployedOnPlatform property Relation between a deployment and the platform on which the system was deployed.
Deployment deployedSystem property Relation between a deployment and the deployed system.
Deployment deploymentProcessPart property Has part relation between a deployment process and its constituent processes.
Deployment hasDeployment property Relation between a System and a Deployment, recording that the System/Sensor was deployed in that Deployment.
Deployment inDeployment property Relation between a Platform and a Deployment, recording that the object was used as a platform for a system/sensor for a particular deployment: as in this PhysicalObject is acting as a Platform inDeployment Deployment.
PlatformSite Platform class An Entity to which other Entities can be attached - particuarly Sensors and other Platforms. For example, a post might act as the Platform, a bouy might act as a Platform, or a fish might act as a Platform for an attached sensor.
PlatformSite attachedSystem property Relation between a Platform and any Systems (e.g., Sensors) that are attached to the Platform.
PlatformSite onPlatform property 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).
OperatingRestriction MaintenanceSchedule class Schedule of maintenance for a system/sensor in the specified conditions.
OperatingRestriction OperatingProperty class An identifiable characteristic of the environmental and other conditions in which the sensor is intended to operate. May include power ranges, power sources, standard configurations, attachments and the like.
OperatingRestriction OperatingRange class The environmental conditions and characteristics of a system/sensor's normal operating environment. Can be used to specify for example the standard environmental conditions in which the sensor is expected to operate (a Condition with no OperatingProperty), or how the environmental and other operating properties relate: i.e., that the maintenance schedule or power requirements differ according to the conditions.
OperatingRestriction SurvivalProperty class An identifiable characteristic that represents the extent of the sensors useful life. Might include for example total battery life or number of recharges, or, for sensors that are used only a fixed number of times, the number of observations that can be made before the sensing capability is depleted.
OperatingRestriction SurvivalRange class The conditions a sensor can be exposed to without damage: i.e., the sensor continues to operate as defined using MeasurementCapability. If, however, the SurvivalRange is exceeded, the sensor is 'damaged' and MeasurementCapability specifications may no longer hold.
OperatingRestriction SystemLifetime class Total useful life of a sensor/system (expressed as total life since manufacture, time in use, number of operations, etc.).
OperatingRestriction hasOperatingProperty property Relation from an OperatingRange to a Property. For example, to a battery lifetime.
OperatingRestriction hasOperatingRange property Relation from a System to an OperatingRange describing the normal operating environment of the System.
OperatingRestriction hasSurvivalProperty property Relation from a SurvivalRange to a Property describing the survial range of a system. For example, to the temperature extreme that a system can withstand before being considered damaged.
OperatingRestriction hasSurvivalRange property A Relation from a System to a SurvivalRange.
