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), 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.

Properties from Observation

Property	Expected Type	description
marginOfError	QuantitativeValue	A marginOfError for an Observation.
measuredProperty	Property	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.
measuredValue	DataType	The measuredValue of an Observation.
observationDate	DateTime	The observationDate of an Observation.
observedNode	StatisticalPopulation	The observedNode of an Observation, often a StatisticalPopulation.

Properties from Thing

Property	Expected Type	description
additionalType	URL	An additional type for the item, typically used for adding more specific types from external vocabularies in microdata syntax. This is a relationship between something and a class that the thing is in. In RDFa syntax, it is better to use the native RDFa syntax - the 'typeof' attribute - for multiple types. Schema.org tools may have only weaker understanding of extra types, in particular those defined externally.
alternateName	Text	An alias for the item.
description	Text	A description of the item.
disambiguatingDescription	Text	A sub property of description. A short description of the item used to disambiguate from other, similar items. Information from other properties (in particular, name) may be necessary for the description to be useful for disambiguation.
identifier	PropertyValue URL Text	The identifier property represents any kind of identifier for any kind of Thing, such as ISBNs, GTIN codes, UUIDs etc.
image	URL ImageObject	An image of the item. This can be a URL or a fully described ImageObject.
instanceOf	Enumeration	Type to which this subject belongs. Use for membership in a value set (Enumeration), not inheritance. Example: K2 instanceOf mountain; volcano subClassOf mountain.
mainEntityOfPage	URL CreativeWork	Indicates a page (or other CreativeWork) for which this thing is the main entity being described. See background notes for details.
name	Text	The name of the item.
potentialAction	Action	Indicates a potential Action, which describes an idealized action in which this thing would play an 'object' role.
sameAs	URL	URL of a reference Web page that unambiguously indicates the item's identity. E.g. the URL of the item's Wikipedia page, Wikidata entry, or official website.
subjectOf	Event CreativeWork	A CreativeWork or Event about this Thing.
url	URL	URL of the item.

Instances of Observation may appear as a value for the following properties

Property	On Types	description
diseaseSpreadStatistics	SpecialAnnouncement	Statistical information about the spread of a disease, either as WebContent, or described directly as a Dataset, or the specific Observations in the dataset. When a WebContent URL is provided, the page indicated might also contain more such markup.
