Before going too far into this, take a look at the name key
<http://wiki.openstreetmap.org/wiki/Name> on the OSM wiki. Also take a
look at the on-the-ground rule
<http://wiki.openstreetmap.org/wiki/Disputes#On_the_Ground_Rule>. OSM
records what is - there's little scope for what was and will be.
Basically name=* is what displays on most of the renderers etc. If most
(local) people and (more importantly) road signs know it as the Blyde
River then that's what should be set in the name=* tag. In such a case
official_name="Motlatse River" is useful.
alt_name=* would probably apply if it were also called Blyde Canyon River.
Of course if the local government's got lots of money for sign changes
(and the people want out with the old) then go ahead and use
name="Motlatse River"; old_name="Blyde River".
Language variations (name:xx=*) might be useful in cases where the
official name is really just the same thing in a different language
(which seems to be the case for Levuvhu vs Levubu, but I'm no language
expert). In these cases it's still a good idea to use
name/official_name/old_name etc.
This naming stuff also applies to names of other things like places,
parks, and streets.
Include the suffix ("River/Stream/Spruit" etc) in the name if known.
It's quite possible to have "Blyde River" tagged as waterway=stream
(waterway=* is a physical/functional tag and would be relevant even if
it was called "Motlatse Street").

Hi
I think the alt name should be the old name. If we do it the other way
around we risk getting involved in politics. Having the old names as
alt names would however be important. More names means it gives
flexibility to have differently rendered maps. You could probably even
go as far as having the old province borders imported as historical
data, not that it would be of much use but might be interesting for
historical purposes.

Hi List!
The OSM data still has the Olifants River, Blyde River, etc.
listed under
their old names.
According to various sources, the official name changed in 2005 to
Lepelle.
http://www.krugerpark.co.za/krugerpark-times-2-15-olifants-river-lepelle-20557.html
So did the names of a number of other places.
Have these name changes never been adopted by the ZA public, and
are therefore
merely an act of the bureaucracy? I think, both names should be in
our data.
Either as name: Lepelle, old_name: Olifants River, or name:
Olifants River,
alt_name: Lepelle. What do you think?
Best,
David
