CSV Import with Custom Annotations #144
Description
Related to #143.
Sometimes the user has other columns on the CSV import that are currently lost during the transformation. These are sometimes user/application specific and are not possible to put in our CSV template. So, we should extend the CSV import to include whatever column is added on top of the template. A pop-up should "warn" the user as it is possible that the user has a typo such as modbus:typ instead of modbus:type which is not a custom annotation.
As a follow-up, we should enable adding another CSV that has the same property names where such custom annotations appear. If the new CSV has overlapping column names, the user should be warned as well.
