Hi Will and all,

Do bring up my volunteering to annotate photos with tags in the meeting. I won't be able to attend, unfortunately. 

Please also note Katja's gallery. Katja and I both have design expertise and we are interested in putting together photos to help orient mappers to the areas being mapped. She wants to focus on the gallery, I want to focus on annotating tags to photos. Of note, in the #1048 - Nepal Earthquake, 2015, Tanahu Task, many buildings are not being mapped because the roofs are dark brown, oval, and thatched in that area of Nepal. Also some buildings there are round or a combination of both, so photos are really useful. 

Just a quick note on community. Through the past weeks I've met wonderful people through HOT. This is a welcoming and vibrant community.

I tentatively plan on being at the meeting

I'd like to help and my proposal is
1. to collect and identify most common tags specific to HOT
2. to mention and document them in Wiki page "Humanitarian_OSM_Tags" [1]

Regarding Point #1, your identification of the popular tags used in HOT activations that aren't well documented but have been used often would be appreciated. 

I think there's been the tendency where attention and participation moves to another crisis after some time even if its not intentional. As a result, any new tags or tagging schemas aren't incorporated into a larger scheme like the HOT/HDM preset. 

The HOT/HDM preset page - https://github.com/hotosm/presets - hasn't been maintained much in the past couple and I sometimes wonder if its still used by many people. Heck, a couple of my pull requests (which aren't controversial) have sat without any response in two years. 
The lack of response and lack of visible use is a small reason that I haven't contributed as much as I had in the past (the largest reason, a full time paid job in an unrelated field). 

As Springfield mentions, there's a few tags in there that don't make sense, but the intention was not only just for a crises but for lower income communities in areas that hadn't been represented in OpenStreetMap and communities that have experienced crises in the past), and to grow OpenStreetMap communities who use tags that don't have an obvious connection to crises. 

Lastly, Suzan, I did see your request and offer of annotating pictures for a tagging guide in a particular area like Nepal! I hope that it is mentioned at tomorrow's meeting! 


So, to begin collecting the candidates, I only foumd these two:
* damage:event=*
* operator:type=private • government • community

The "idp:camp_site=spontaneous_camp" is already sub-specific to a
disaster event.

Any others tag or key candidates?

Yours, S.
