example of query for metrics and miniprod
Can you provide an example of simple query for a list of metrics? for a list of miniprods?
As a reminder, we define here a "metrics" equivalent as either :
- a single parameter value from the in situ dataset : it can be for instance a value of sea_surface_temperature if so is named the sst in iQUAM. Extracting these simple metrics is just extracting values from the in situ server. In this case of course, metrics are not statisical values (no mean, std, etc... just single values)
- an operation on a miniprod, exactly like in felyx that would return a single value, for instance mean(miniprod(sea_surface_temperature)). This is completely in line with felyx processing workflow when you process dynamic metrics.
We define the "miniprod" equivalent as : the miniprod in the in situ server context is a history of some single parameter values. So it is an extension of the metric since you provide a series of values (centered on the requested time) instead of the single closest value. Why don't I call single values miniprods (which would be reduce to just one value) ? I could have... but I have considered that calling them metrics, they can be directly compared with felyx metrics (for instance in situ value against the central value of a dynamic miniprod).
