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 v5.0.0

DESCRIPTION

Instances of the class Observation are used to specify observations about an entity (which may or may not be an instance of a StatisticalPopulation), at a particular time. The principal properties of an 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 StatisticalPopulation, and the data and datasets overview for more details.

ATTRIBUTES

margin_of_error

marginOfError

A marginOfError for an Observation.

A margin_of_error should be one of the following types:

Str

measured_property

measuredProperty

The measuredProperty of an 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']

measured_value

measuredValue

The measuredValue of an Observation.

A measured_value should be one of the following types:

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

observation_date

observationDate

The observationDate of an Observation.

A observation_date should be one of the following types:

Str

observed_node

observedNode

The observedNode of an Observation, often a StatisticalPopulation.

A observed_node should be one of the following types:

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