As far as I remember: these three columns are not supported by osmconvert when generating CSV files.
Maybe the program can be expanded accordingly… For what purpose do you need these columns? There might be another way to get these data.
I checked the xml-file beforehand. these data are contained in the node tag. thanks anyway, as sometimes you miss the obvious.
Thanks for the info. I just wanted to make sure not to miss something.
I found a work-around: I used ArcGIS OSM Editor (that was at hand, I am sure that there is a QGIS equivalent) to get the timestamp and version data - however, the ArcGIS OSM Editor does not supply all tag information. So, I combined this in R with the csv-output from osmconvert.
What do I do with the data? I am interested in what was mapped when to feed into a scientific study on representation of certain phenomena in different kind of maps (OSM is just one of them).
Thanks for the explanation; I was just curious, because I did not expect these data to be needed in a CSV list.
Some minutes ago I uploaded osmconvert version 0.7R. The missing header tags @version, @timestamp and @changeset have been added. This might ease your toolchain a bit and perhaps could help other users as well.
