dr-shorthair has just created a new issue for https://github.com/w3c/sdw:

== Homogeneity of an ObservationCollection ==
According to the proposal [1] an ObservationCollection should be homogeneous in one or more of

feature-of-interest
ultimate feature-of-interest
observed-property
procedure
sensor
phenomenon-time
result-time
i.e. ObservationCollections can be homogeneous on different properties.

See discussion here [2] for confirmation that addition of this class might accommodate several existing use-cases, for example streaming.

While the requirement for 'one or more' are not yet axiomatized, that would be a relatively easy tweak.
This issue to host discussion of whether these homogeneity constraints are enough or too much.
