As is shop=*. They are both not purely main objects, but also not purely attributes. You go to a building because the shop you want to visit is in it; you go to a building because you want to go to the blood collection.

If the building is not primarily the shop, you tag the building with building=* and place a node inside with just the shop tags. Similarly for healthcare=blood_donation.

This is a bit philosophical.

> * also applying to healthcare=any (to be modified): the tag can be put on an area object (typically building), but, preferably IMHO, unless the whole area is devoted to donation, a node inside an area.  In that case, having an object tag such as a room in the node is required (you said you are happy without)

I did not previously understand your call for a 'room' tag. Indeed I am happy without a room tag if the building is not indoor mapped. If indoor mapping ever catches on, the outlines of rooms where blood donation takes place can be tagged with room=yes and healthcare=blood_donation.

opening_hours=Tu 17:00-19:30 "days on schedule (see website)" seems far from perfect. Semantically, IMO, it is implied that the facility is open every Tuesday, with a comment for the user. Perhaps the opening_hours syntax could be amended.
Another problem is that the mobile collections don't always occur on the same day of the week. For example, in Heist, Belgium, The upcoming mobile collections are We 19 August, Tu 25 August, Tu 10 November and We 18 November.

I am not convinced that the mobile blood donations can be adequately mapped by this. They would at least need an additional tag. Also, they are points that are fixed in space, but not in time. OpenStreetMap normally requires both I think.

However, I do like the idea of mapping them. Maybe we can ultimately get our Red Crosses to use OSM maps on their sites.

Thank you for elaborating on your point of view. I now better understand what you meant.
