Interesting idea.<br><br>I would be inclined to try to make it work with existing tagging schemes rather than invent a new one (would mean you could use an existing routing application with little, if any modification).<br>
<br>There is not really a significant difference between this and a multi-level road interchange is there? This would mean we could use 'layer=xxx' to show the floors.<br>The main addition would have to be a tag for an elevator - stairs are really just footpaths, and there is already a tag for them.<br>
<br>The main problem may come in editors - how to select the correct node, way etc when there are lots on top of each other.<br><br>Therefore I think it should be achievable without too much trouble in terms of the data analysis, but it might need a modification to an editor.<br>

<div>Dear all,</div>
<div> </div>
<div>
<div>On July 5th there has been a featured image of an inhouse route to FH Hannover Campus (c.f. <a href="http://wiki.openstreetmap.org/wiki/Featured_images" target="_blank">http://wiki.openstreetmap.org/wiki/Featured_images</a>)</div>
<div> </div></div>
<div>Are there any opinions and proposals on handle indoor routing?</div>
<div> </div>
<div>Indoors means to me among others to have </div>
<div>* floors (elevation/altitude is not enough!)</div>
<div>* stairways, escalators </div>
<div>* and lifts between floors. </div>
<div> </div>
<div>
<div>1. Is it possible to handle that many topologically only partially connected ways (graphs)? </div>2. How to tag this? With "level=2"? or better with floor=2?</div>
<div>3. How about several nodes (on different floors) with the 'same' coordinate but different elevation/altitude?</div>
<div> </div>
<div>Yours,</div>
<div>S.</div>
