Also, if I wanted to capture specific data about that they offered,
I'd like to follow the amenity:recycling tagging scheme
(http://wiki.openstreetmap.org/wiki/Tag:amenity%3Drecycling):
+ homeless_shelter:programs=jobs
+ homeless_shelter:meals_served=breakfast
+ homeless_shelter:lodging=yes
+ homeless_shelter:emergency_medical=yes
Is this a good model to follow?
I'm not sure.
I think, there are two general approaches to simulate a tree-style
tagging scheme like this.
The first is to use more keys (as you do here with homeless_shelter:*),
the second is to use more values and to concatenate multiple values by ;
(like you will have at
homeless_shelter:meals_served=breakfast;lunch
(compare crossing=island;traffic_signals)
Both are good for some reasons:
using less keys provides easy access for the whole group of values;
using less values is more easy to parse and search - there is no string
slicing needed.
But:
I would not mix these together.
Perhaps that's only my POV - feel free to argument against.

Peter
