[Accessibility] adding maps inside of buildings

[Parker, Anson D (adp6j)]

hi - i'm working with the university of virginia to get our CAD maps of buildings - especially inside of the hospital where i work - made available in OSM.   what are the best practices for this?  i would like to add maps that include wayfinding information for wheelchaired and vision impaired people

are there any online tutorials for going from DXF -> OSM.  one specific question is how is 3d data like stairwells best communicated?

here's a working document of what we've done so far

any comments welcome!

thanks
