Import Type
This is a semi-automated import that uses Ogr2osm and a script that converts polygons to relations, and adds tags [2] made by User:Stalker. That is a modified script from michigantownships twptranslation.py [3]. The whole command is: python3 ../ogr2osm/ogr2osm.py -t smz-translation.py -f --split-ways=1 -o smz.osm naselja.shp
Data Preparation
Tagging Plans
Tags that will be put on boundary relations:
name=* < NA_IME from the DGU geojson
ref:hr:maticni_broj=* < NA_MB from the DGU geojson
Tags that will be put on boundary ways:

Data Merge Workflow
Team Approach
The data is pretty straightforward, so Janko Mihelić will do the manual part of the import.
Dedicated user account
The user under which the import will be done is called Import DGU borders.
Workflow
The fore mentioned tools will make the .osm file to be imported. Importing will be done manually, way by way. During this, history of old borders will be preserved by copying them to some of the smaller borders.
