Projects/Oxygen/namingSpec
Here you will find the newest info about the implementation of namespaces found on freedesktop.org.
Note that this is still a study of work in motion
Concrete action proposals for Oxygen as well as the icon naming specification itself can be found for the following categories: actions, apps, categories, devices, places, status, animations, emblems, emotes, mimetypes.
The following list (thanks go to Jonathan Riddell) was used for the initial conversion of icon names and should not be considered the definitive resource for KDE 3/4 icon name relations as it's incomplete and probably outdated for some of the icon names. The pages linked above contain more current, but probably still incomplete name mappings.
The format is <standard-name> <kde3-name> <status>
NEW is new use for an icon
NONE is doesn't exist at all in kde 3
