This includes two things: First, we relax the assumption that a geometry column must be present and let the actual handler implementation decide to add the dimension lco option. Second, we introduce a prepare_import step to the interface. Here, any customizations can be done before the actual import starts. Actual implementation of the datapackage handler moved to the contribs repository and can be installed as mere dependency. * Tests if prepare_import is called --------- Co-authored-by: Giovanni Allegri <giovanni.allegri@gmail.com> Co-authored-by: Henning Bredel <h.bredel@gmx.de>

As you know the new importer misses the CSV handler. We were waiting to implement a solution that should replace the upload steps that we have now, where the lat/lon column can be selected at upload time.
We cannot afford to implement a new UI for the custom selection of columns, so our proposal would be the following:
preconfigure the CSV handler with OGR X_POSSIBLE_NAMES="x,lon*" and Y_POSSIBLE_NAMES="y,lat*" options
accept a companion "*.csvt" file, as supported by the OGR CSV driver
This solution would provide an alternative that's not too expensive and complex to implement, and gives the opportunity to remove the current upload system (at the moment it's still required only for CSV files).
I'm not against the solution based on Tabular Data Resource and VSI.
I think all these options could coexist, letting the handler pick up the best depending on the provided files, with X_POSSIBLE_NAMES and Y_POSSIBLE_NAMES preconfigurations as a fallback.
What's your opinion?
