JOSM support for Maastotietokanta GML scheme?

Hi everyone,

I thought about starting to work on JOSM support for supporting NLS’ Maastotietokanta scheme? Is anyone working on this already?
Or do you know any related work, i.e. Maastotietokanta GML to OSM/PBF converters or anything?

Would anyone be interested to work on this together?

Thanks,

Dominik
