NAME

SemanticWeb::Schema::Observation - Instances of the class [[Observation]] are used to specify observations about an entity (which may or may not be an instance of a [[StatisticalPopulation]])

VERSION

version v14.0.0

DESCRIPTION

Instances of the class SemanticWeb::Schema::Observation are used to specify observations about an entity (which may or may not be an instance of a SemanticWeb::Schema::StatisticalPopulation), at a particular time. The principal properties of an SemanticWeb::Schema::Observation are [[observedNode]], [[measuredProperty]], [[measuredValue]] (or [[median]], etc.) and [[observationDate]] ([[measuredProperty]] properties can, but need not always, be W3C RDF Data Cube "measure properties", as in the lifeExpectancy example). See also SemanticWeb::Schema::StatisticalPopulation, and the data and datasets overview for more details.

ATTRIBUTES

margin_of_error

marginOfError

A marginOfError for an SemanticWeb::Schema::Observation.

A margin_of_error should be one of the following types:

InstanceOf['SemanticWeb::Schema::QuantitativeValue']

_has_margin_of_error

A predicate for the "margin_of_error" attribute.

measured_property

measuredProperty

The measuredProperty of an SemanticWeb::Schema::Observation, either a schema.org property, a property from other RDF-compatible systems e.g. W3C RDF Data Cube, or schema.org extensions such as GS1's.

A measured_property should be one of the following types:

InstanceOf['SemanticWeb::Schema::Property']

_has_measured_property

A predicate for the "measured_property" attribute.

measured_value

measuredValue

The measuredValue of an SemanticWeb::Schema::Observation.

A measured_value should be one of the following types:

InstanceOf['SemanticWeb::Schema::DataType']

_has_measured_value

A predicate for the "measured_value" attribute.

observation_date

observationDate

The observationDate of an SemanticWeb::Schema::Observation.

A observation_date should be one of the following types:

Str

_has_observation_date

A predicate for the "observation_date" attribute.

observed_node

observedNode

The observedNode of an SemanticWeb::Schema::Observation, often a SemanticWeb::Schema::StatisticalPopulation.

A observed_node should be one of the following types:

InstanceOf['SemanticWeb::Schema::StatisticalPopulation']

_has_observed_node

A predicate for the "observed_node" attribute.
