Hi All,
Kathmandu Living Labs took the time to compile a really useful tagging guide specific to Nepal. 
There’s one specific tagging guide for roads here: http://wiki.openstreetmap.org/wiki/Nepal/Roads
There’s a more general Nepal tagging guide here: https://docs.google.com/spreadsheet/ccc?key=0AmYd3Y40Dfk8dGk4TzgtVmE5RExMVGNncEEzb2JtSHc&usp=drive_web#gid=0
I would strongly recommend following KLL’s guidelines wherever possible, they put a lot of thought into crafting a tagging scheme specific to Nepal’s context.
And for those who don’t know, a galli is an alley. Very useful word in Kathmandu :)

I also saw a lot of inconsistencies. You can try to contact directly Nama Budathoki on this list and from Kathmandu living lab in Kathandu.
They have some difficulties and they might not be online. 

If you cannot contact, I suggest that you start to revise.

There seems to be inconsistencies in how the roads are classified, with many National Highways being marked as trunk, primary, secondary, tertiary and even unclassified.
Based on http://wiki.openstreetmap.org/wiki/Nepal/Roads#Road_Classification and my own experience with roads in India, the tagging should probably be more like this:
Trunk National Highway (ref=H##): trunkFeeder Roads (ref=F##): primaryDistrict Roads (ref=D##): secondary
used with appropriate surface=* tag
Can someone from the ground make any recommendations based on practical use? There does not seem to be any comprehensive documentation of how the existing tagging scheme came about and it looks quite messy.
The forum has some discussion about this with no clear consensus: http://forum.openstreetmap.org/viewtopic.php?id=30221
