[OSM-talk] OSMHQ GIS Data Model

I've started working on a GIS Data Model for OSMHQ. As part of this
work I have defined a list of thematic layers, a set of standard tags
for each OSMHQ feature, and a list of feature types in the first
thematic layer, the Vehicle Road Network. If you are interested in
OSMHQ, or improving the quality of OSM trough recommended tag sets and
mapping procedures please respond with your ideas for improving what
I've done so far.

If there is enough interest, perhaps I can add some documentation on
this GIS data model and the tool chain that supports it to the OSM
wiki?

Vehicle Transportation Network Layer Non Spatial Feature Types
- Roads ( A Road feature is a collection of related road segments that
share either a primary road name/identity or a physical route.)

Vehicle Transportation Network Layer Relations/Relationships
- Road Segments To Road Crossings
