If you want the meta data, you can have it in a separate database. :) And donate all your corrections back to the source provider. Using the FME GIS application from SAFE. This product provides that option. (All i know is that it works.. but i dont know how it does) ... others do. http://www.safe.com/ Natural Resources Canada will be using it as a way to enhance the source dataset with the more accurate OSM data, and creating a DIFF dataset. (which shows the difference between the source versions, so then the next available dataset will be much smaller, as it only includes the 'missing data' ) And in return for that, Natural Resources Canada is creating .osm files the size of nice NTS tiles (and smaller quad-tree tiles) ie. .1x.1 degrees for those areas with a hi-density of data. (so local people can view all of the features into a single combined .osm file) Osmosis can also do this, but i think an algorithm still needs to be made to line up with degree tiles. (which tile-splitter can possibly help). I hope im saying that correctly. So using a combination of both, the WMS layer from the source data & the .osm files. It should make for more happy campers all around. Cheers, Sam p.s. Some folks on the main #osm IRC chat might be happy discuss it also :-)
