Congratulations. It’s good to see another link in the 3D chain come to life.
@viw: the models are already included in the OSM3D browser, which runs in a Java plugin. Including the models in osm2world or other 3D models is a decision / work for the developers of those services, but I am sure they are thinking about it. As noted in the wiki, they need an API first.
@Matthias: Is there a way to facilitate “collaborative editing”? The current way the system works suggests that there is only one definitive model for each building. It would be nice to encourage people to improve models. This can currently be done by downloading, editing, reuploading, although it’s not clear whether a second upload will be possible. A nice feature would be to use something like git to track differences, allow side-by-side comparison, reverting and so on.
A couple of quick usability points: the ‘more’ links in the popups sometimes open a new browser tab, sometimes don’t. The header on the detail pages doesn’t link to home, it links to the page already open. Both of these can be confusing!
