Realization string Id instead of realization index? #18

Closed stefhummel closed 3 years ago

stefhummel commented 3 years ago

In FEWS, a member of ensemble run has an ensemble member id, which is a string. In the DD-GRID-API it is an integer. To support string id's, we could simply redinen 'realization' as string instead of int, because the integer index value would perfectly fit into a string. However, this leads to problems in defining the realization axis in the 'envelope' and 'domainSet'. To be discussed.

The purpose of the id, I guess, would be an immutable identifier, while Id actually is an index? In that case, would an additional property instead of the string id make sense? Perhaps ExternalKey?

(After team discussion) We will make the realization 'index' a string. How to express the axis in the meta data is yet to be elaborated. For requesting the data for a certain realization, we will use the generic filtering mechanism as defined in the DD-API. In fact this has to be adjusted also in the DD-API. We will create an issue for this.
