Hi Pitscheplatsch,
I am part of the team lead for IDEAMAPS asset mapping. We were trained to upload and update the OSM in the survey area. We were asked to put every name in lowercase and underscore to separate the words. 
Currently, we have lots of survey POI data validated by the community and IDEAMAPS team. How can you advise on uploading our survey data successfully?

Thank you,
Sabitu
