Datastream is quite "homogeneous" as it tries to represent single streams of data,
![Sensor Things API data model (sensing)](https://upload.wikimedia.org/wikipedia/commons/thumb/5/57/SensorThings_API_data_model.svg/991px-SensorThings_API_data_model.svg.png) 

namely each observation in a Datastream has the same Sensor, ObservedProperty, and Thing (may be equivalent to sosa:Platform). It doesn't necessarily have the same FoI and generally does not have the same phenomenonTime or validTime. An alignment should have those homogeneity constraints.

I'm wondering if it might be helpful to create a Sensor Things ontology for the purposes of alignment.
