PartialEntry #57

Closed mmaelicke closed 4 years ago

mmaelicke commented 4 years ago

@MarcusStrobl , we had another discussion about Eddy data yesterday and concluded, that we need to introduce a new column to Entry, called is_partial, a boolean column that is False by default. If an Entry is partial, it has to be part of a EntryGroup of type==composite. The metadata described by these kind of Entry do only make sense in conjunction with the other Entry records in the same composite, while the others are self-contained and also make sense without the partial Entry.

Example

The Eddy data in principle consists of wind measurements (Entry no. 1), e.g. CO2 fluxes (Entry no. 2) and Covariances between all the components (<- partial Entry). It makes sense to use only wind measurements or CO2 fluxes and not caring about the Eddy tower. You can use either without the other. But if you are interested in Eddy, you need all three. Thus if a user searches for wind, he should find Entry no. 1 (and only that), with a note that the data is part of a composite. If he searches for Eddy (the EntryGroup) and 'clicks' on Entry no. 1, the system has to load Entry no.1, no. 2 and the partial Entry. The partial Entry itself does not make any sense like this and should not be found.
