SchemaHttpObservation class

Observation class from SchemaHttp vocabulary

Instances of the class {Observation} are used to specify observations about an entity at a particular time. The principal properties of an {Observation} are {observationAbout}, {measuredProperty}, {statType}, {value and {observationDate} and {measuredProperty}. Some but not all Observations represent a {QuantitativeValue}. Quantitative observations can be about a {StatisticalVariable}, which is an abstract specification about which we can make observations that are grounded at a particular location and time.

Observations can also encode a subset of simple RDF-like statements (its observationAbout, a StatisticalVariable, defining the measuredPoperty; its observationAbout property indicating the entity the statement is about, and {value} )

In the context of a quantitative knowledge graph, typical properties could include {measuredProperty}, {observationAbout}, {observationDate}, {value}, {unitCode}, {unitText}, {measurementMethod}.
