<div dir="ltr">One problem with multipolygon relation is that by definition you can't put <u>node </u>it those and you can't put <u>contiguous buildings</u> either. How do you group "node + polygons + multipolygon" (some buildings are a multipolygon already where the hole is not part of the university ^_^) with other thing than a site relation ? If you have any suggestion feel free to share as i never find anything else (and we already discussed it in the past on this mailing list, always to say "okay it is the best fit for the time being"). :-)<div><br></div><div>You can't put big polygon around these things either, as many of these "city university" don't own the ground around the building (they are really in the middle of the city spread across it) and as you said, many parts are only an "office" in a building shared with other companies or services (so only nodes in OSM). </div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">Le jeu. 6 févr. 2020 à 02:58, Joseph Eisenberg <<a href="mailto:joseph.eisenberg@gmail.com">joseph.eisenberg@gmail.com</a>> a écrit :<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">> ... put the tag "amenity=university" and all the information only 1 time for the whole university<br>

+1 for the common multipolygon relation, not type=site.<br>
