Related Thing, Datastream, Observation, Feature #172

Open hylkevds opened 5 months ago

Self-relations for the EntityTypes Thing, Datastream, Observation and Feature are quite common. Like #65, and the RelatedDatastream concept of STAplus.

The current proposal (#167) adds a Relations Extension: Datamodel-SensorThingsApi-V2-RelationsFull drawio

Open Question: do we need a time (TM_Object or TM_Instant) on these relations?
