Hi Stefan,

HOT (and OSM) tagging has grown and evolved since we first started 5 or 
6 years ago that is for sure. And given the somewhat intermittent 
participatory nature of OSM and the wiki things can for sure get out of 

We would welcome any assistance with updating, streamlining and 
regularizing HOT's tagging and tagging guidance and underlying data 
model if need be. It is a big project for the folks in and out of HOT 
who developed and maintain it.

It was through gentle ;) feedback from the OSM community that we have 
started use some more planned tagging schemes you mentioned so there is 
yet time for some of that to catch up.

I am excited for us to roll up our sleeves and give the tagging, 
guidance, data model and rendering a timely review and updating. At the 
moment many in HOT are concentrating on working with our fellow 
travelers in Nepal (and DRC and Vanuatu and Guam and South Sudan and 
Nigeria and several other places unfortunately), but when that begins to 
thankfully be less of an urgent matter several of us look forward to 
joining you fully in the process.

And like I said, any reorganization or updating and streaming in the 
wiki you could help us with in the mean time will be very welcome and 
appreciated. If you have any questions please just ask them here on the 
mailing list but under a different email thread so it is less confusing 
talking about something that has nothing to do with this thread.
