Hi, I'm not quite sure what you mean, but I'm guessing you mean creating a new node within the building that has the reference number. Which (and I apologise if I am wrong) sounds like you are tagging for the render rather than being true to whats there.
I'd personally put the ref tag on the building itself, failing that if you want to be specific I would create a node on the outline of the building where the entrance is and tag that. At least then the node is directly associated with the way that forms the building. Though this seems pointless as there are a variety of entrances to many buildings, tagging them all seems like a waste of time. Common sense tells you to walk around the outside until you find a way in ;) Hope that helps, Ciarán _______________________________________________ Talk-gb-westmidlands mailing list Talk-gb-westmidlands@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb-westmidlands
