This project is not what you think it is.
DZK developers might not even know about this project, it does not use data from data.land.gov.ua. Don't use data as an official source of information.
The only initial goal was to collect parcel addresses for the OSM project.
There are no plans to do something with data or setup regular updates, but author can give you whatever raw data you want.
Use maputnik as WYSIWYG editor
