I have shared my presentation from SOTM Africa here:
https://drive.google.com/open?id=0B_2QVFnCIYvpQllEWnR2bWhTVnM

There are quite a few photographs of different types of roads in Africa
along with the aerial view.

At the workshop in Kampala there was a good deal of discussion and
frustration expressed regarding inconsistencies in descriptions and usage.
There was not a consensus that additional tags were needed, however, there
was general agreement that the Africa Highway Tagging Guide needed some
clarification.
There was a suggestion that the editing software could have regional tag
exclusions. An example would be highway=living_street, a legally defined
type road that is not found in Africa.

I like the guidance Bjoern gave us below and the nice presentation. My only
suggestion would be that metal roofs could be one factor in determining
path/residential/unclassified. I have seen many remote villages only
accessible by path that have some metal roofs.  I think the same could be
true in Nepal?

Here is a draft 1-page document for use in mapathons

The order of tag listing is "upside down" emphasizing the most common
routes first.  highway=service should probably be added and primary could
be dropped.

Let's continue this conversation.

Regards,

Emmor
