INTERLIS Import last_modification is updated also with append

[sjib]

Describe the bug A clear and concise description of what the bug is.

When re-importing the same dataset e.g. organisation it shows in the wizard, that it already exists and only appends new data. (append mode).

The strange thing is, that also for the existing objects in this append mode, the last_modification field is updated.

Expected behavior A clear and concise description of what you expected to happen.

In append mode (as currently implemented) existing datas last_modification field should not be updated to the time of a re-import. This behaviour should be implemented in a update mode, when an existing dataset is really updated and e.g. an attribute is changed.

If we import a dataset and re-import it the last_modification is changed. Shouldn't the last_modification of the import data (what is in the xtf) be kept? Or is importing data in another system considered a modification?

Is this a behaviour we want or not? @cymed @teksi/technical-group

I think we don't want this behaviour. I suggest the same strategy as with enabling/disabling symbology triggers
