OSM Protocol Stack Overview

OSM Protocol Specification Versions

• OSM Protocol Specification Version 0.3 (no longer used)

• OSM Protocol Specification Version 0.4 (no longer used)

• OSM Protocol Specification Version 0.5 (currently used)

• OSM Protocol Specification Version 0.6 (not before TomH has reviewed changes and certainly not by mid May)

You can insert the template {{not 0.5 compatible}} on a wiki page if it describes something that doesn't work with the current API version. This is very helpful for people that aren't uptodate with how OSM works.
