Schema.org SOSA schema

This is an RDFa-based representation of the SOSA schema, a schema.org compatible representation of the core module of the W3C Semantic Sensor Network vocabulary.

Observation Act of carrying out an (Observation) Procedure to estimate or calculate a value of a property of a FeatureOfInterest. Links to a Sensor to describe what made the Observation and how; links to an ObservableProperty to describe what the result is an estimate of, and to a FeatureOfInterest to detail what that property was associated with. Candidate for schema.org Subclass of: Action
Sampling An act of Sampling carries out a sampling Procedure to create or transform one or more samples. Candidate for schema.org Subclass of: Action
Actuation An Actuation carries out an (Actuation) Procedure to change the state of the world using an Actuator. Candidate for schema.org Subclass of: Action
Procedure A workflow, protocol, plan, algorithm, or computational method specifying how to make an Observation, create a Sample, or make a change to the state of the world (via an Actuator). A Procedure is re-usable, and might be involved in many Observations, Samplings, or Actuations. It explains the steps to be carried out to arrive at reproducible results. Candidate for schema.org Subclass of: Intangible
Sensor Device, agent (including humans), or software (simulation) involved in, or implementing, a Procedure. Sensors respond to a stimulus, e.g., a change in the environment, or input data composed from the results of prior Observations, and generate a Result. Sensors can be hosted by Platforms. Candidate for schema.org Subclass of: Thing
Sampler A device that is used by, or implements, a Sampling Procedure to create or transform one or more samples. Candidate for schema.org Subclass of: Thing
Actuator A device that is used by, or implements, an (Actuation) Procedure that changes the state of the world. Candidate for schema.org Subclass of: Thing
Feature Of Interest The thing whose property is being estimated or calculated in the course of an Observation to arrive at a Result or whose property is being manipulated by an Actuator, or which is being sampled or transformed in an act of Sampling. Candidate for schema.org Subclass of: Thing
Observable Property An observable quality (property, characteristic) of a FeatureOfInterest. Candidate for schema.org Subclass of: Property
Actuatable Property An actuatable quality (property, characteristic) of a FeatureOfInterest. Candidate for schema.org Subclass of: Property
Result The Result of an Observation, Actuation, or act of Sampling. To store an observation's simple result value one can use the hasSimpleResult property. Candidate for schema.org Subclass of: Thing
Sample A Sample is the result from an act of Sampling. Feature which is intended to be representative of a FeatureOfInterest on which Observations may be made. Samples are artifacts of an observational strategy, and have no significant function outside of their role in the observation process. The characteristics of the samples themselves are of little interest, except perhaps to the manager of a sampling campaign. A Sample is intended to sample some FatureOfInterest, so there is an expectation of at least one isSampleOf property. However, in some cases the identity, and even the exact type, of the sampled feature may not be known when observations are made using the sampling features. Physical samples are sometimes known as 'specimens'. Candidate for schema.org Subclass of: Thing
Platform A Platform is an entity that hosts other entities, particularly Sensors, Actuators, Samplers, and other Platforms. Candidate for schema.org Subclass of: Thing
has feature of interest A relation between an Observation and the entity whose quality was observed, or between an Actuation and the entity whose property was modified, or between an act of Sampling and the entity that was sampled. Candidate for schema.org Domain: Sampling Domain: Observation Domain: Actuation Range: FeatureOfInterest Range: Sample
is feature of interest of A relation between a FeatureOfInterest and an Observation about it, an Actuation acting on it, or an act of Sampling that sampled it. Candidate for schema.org Domain: FeatureOfInterest Domain: Sample Range: Actuation Range: Sampling Range: Observation
observed property Relation linking an Observation to the property that was observed. The ObservableProperty should be a property of the FeatureOfInterest (linked by hasFeatureOfInterest) of this Observation. Candidate for schema.org Domain: Observation Range: ObservableProperty
phenomenon time The time that the Result of an Observation, Actuation or Sampling applies to the FeatureOfInterest. Not necessarily the same as the resultTime. May be an Interval or an Instant, or some other compound TemporalEntity. Candidate for schema.org Domain: Actuation Domain: Sampling Domain: Observation Range: TemporalEntity
result time The result time is the instant of time when the Observation, Actuation or Sampling activity was completed. Candidate for schema.org Domain: Sampling Domain: Actuation Domain: Observation
has result Relation linking an Observation or Actuation or act of Sampling and a Result or Sample. Candidate for schema.org Domain: Actuation Domain: Sampling Domain: Observation Range: Sample Range: Result
is result of Relation linking a Result to the Observation or Actuation or act of Sampling that created or caused it. Candidate for schema.org Domain: Sample Domain: Result Range: Actuation Range: Sampling Range: Observation
used procedure A relation to link to a re-usable Procedure used in making an Observation, an Actuation, or a Sample, typically through a Sensor, Actuator or Sampler. Candidate for schema.org Domain: Sampling Domain: Actuation Domain: Observation Range: Procedure
measurementTechnique A technique or technology used in a Dataset (or DataDownload, DataCatalog), corresponding to the method used for measuring the corresponding variable(s) (described using variableMeasured). This is oriented towards scientific and scholarly dataset publication but may have broader applicability; it is not intended as a full representation of measurement, but rather as a high level summary for dataset discovery. For example, if variableMeasured is: molecule concentration, measurementTechnique could be: "mass spectrometry" or "nmr spectroscopy" or "colorimetry" or "immunofluorescence". If the variableMeasured is "depression rating", the measurementTechnique could be "Zung Scale" or "HAM-D" or "Beck Depression Inventory". If there are several variableMeasured properties recorded for some given data object, use a PropertyValue for each variableMeasured and attach the corresponding measurementTechnique.
