Observation results may have many data types, including primitive types like category or measure, but also more complex types such as time, location and geometry [OGC 10-004r3 and ISO 19156:2011]. SensorThings’ MultiDatastream entity is an extension to handle complex observations when the result is an array.

A MultiDatastream groups a collection of Observations and the Observations in a MultiDatastream have a complex result type.
