Metadatamanagement: Are we able to import and represent long-format-data?

[AndyDaniel1]

We need to discuss in general if we're currently able to import and represent long-format-data properly.

@rbirkelbach adressed in issue #1834 one question in this context

[rbirkelbach]

| t | v |
|---|---|
| 1 | 1 |
| 1 | 2 |
| 2 | 3 |
| 2 | 4 |

Variable details site for variable v has choser where you can select t.

[AndyDaniel1]

The MDM currently cannot display the distributions of long format variables.

Question: does this pose a problem for the user?

[rreitmann]

For various reasons (dataset report, one distribution per variable) the MDM supports only the wide format which contains one variable per value of t (v_1, v_2). These can be connected by panelIdentifier. We can implement a dropdown on the variable details page (of v_1) in which the user can select the associated variables (v_2)
