Thanks for all the work on the interior of Ablah Library! Just a couple requests:
1) could you please review https://wiki.openstreetmap.org/wiki/Simple_Indoor_Tagging and the examples listed? Please note that walls are lines, not areas. Also, walls for rooms should be connected and simplified a bit from how you mapped them.
2) The use of amenity=chair seems like it might be misused here... Please note that amenity=chair is a chair that doesn't move (is fixed in one place) see: https://wiki.openstreetmap.org/wiki/Tag:amenity=chair
