ObservationCollection

[mbeaufils]

As defined in OMS :

A collection of similar Observations #19

[LucasoilCloud]

For each observation, we can add a property, for example 'CollectionReference'. Like that it would be easy to connect each observation of a same set of observations together.

What it is important, I think is not to confuse a collection of observation with a type of observation. For example, if we have 2 boreholes SPT_1 and SPT_2 with 2 NSPT value. In total, we have 4 observations (2 in each borehole). Here, all these 4 observations has the type 'SPT', 2 have 'SPT1' has 'CollectionReference' property and the 2 others have 'SPT2' has 'CollectionReference' property.

Following the ObservationTypology discussed in April.

Several specializations of ObservationCollection are proposed:

• Serie Observation : A collection of Observations that observed the same property thanks to the same procedure repeated in either time or space,
• Parallel Observation : A collection of Observations obtained by following a unique procedure that adress several observed properties based on a single act of observation,
• Parallel series : A collection of Serie Observations that themselves address one ObservedProperty.
• Serie of ParallelObservations : A collection of ParallelObservations. ParallelObservations that are repeated in either time or space.
