ObservationClass
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.

Property Expected Type TMPC Mapping description marginOfError A marginOfError for an Observation.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.measuredValue The measuredValue of an Observation.observationDate DateTimeThe observationDate of an Observation.observedNode The observedNode of an Observation, often a StatisticalPopulation.- Properties from Thing
Property Expected Type TMPC Mapping description additionalType URLAn 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 TextAn alias for the item.description TextA description of the item.disambiguatingDescription TextA 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 The identifier property represents any kind of identifier for any kind of Thing, such as ISBNs, GTIN codes, UUIDs etc. Schema.org provides dedicated properties for representing many of these, either as textual strings or as URL (URI) links. See background notes for more details.image URLImageObjectAn image of the item. This can be a URL or a fully described ImageObject.mainEntityOfPage URLCreativeWorkIndicates a page (or other CreativeWork) for which this thing is the main entity being described. See background notes for details.name TextThe name of the item.potentialAction Indicates a potential Action, which describes an idealized action in which this thing would play an 'object' role.sameAs URLURL 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 A CreativeWork or Event about this Thing.url URLURL of the item.- Instances of Observation may appear with as a value for the following properties

When a WebContent URL is provided, the page indicated might also contain more such markup.- Superseded by
