From time to time I copy the administrative borders of Luxembourg into OSM. As the legally available data is only coarse, this boarders should only be considered as a first approach.
I add also some minor details as well as some relations on the public transportation etc
Furthermore I correct the OSM based on "Keep Right" and "OSM Inspector".
Recently (2010/12) I have added some "status" columns in the Luxembourg OSM-Wiki [].
I have started to create maps, which shows the status of the different projects (, WikiProject Luxembourg/Public Transport, WikiProject Luxembourg/Cycle Route Network). For rendering I use the data from the site Geofabrik. These data are imported with osm2pgsql to a PostgreSQL Database, where they are treated. Visualization is done with Qunatum GIS.
Some of my used Maperitive Codes are shown here: Loll78:Maperitive-Codes
