I think that it is a poor assumption to make that there exists a one to one mapping between objects (nodes, ways, relations) tagged with amenity=university, and actual organisations. For example, you would not count the roads in a town by looking at all ways tagged with highway=(primary|secondary) in that town, as more than one way can make up just one named road. > I think someone mentioned Cambridge Uni was using OpenStreetMap for > some of its maps,* so I'd be nervous about proposing anything radical > right now.

Alternatively there are tags in use such as > building=university which might be good drop-in replacements... I have been doing some things around the University of Southampton, I have just made an attempt to bring the wiki page a bit more up to date [1]. It should now cover some of the basics. As for the tagging, for the University of Southampton, none of the software that I have written (e.g. [2]) relies on amenity=university. I am pretty much only relying on the URI's (uri tag) to link out of OpenStreetMap. This allows for going in to OpenStreetMap and identifying bits of information. In summary, I am not sure what amenity=university means, or should mean, however, it obviously plays a part in rendering OSM. I am unsure about relations, I think it remains to be seen if they are fit for purpose in this regard. 1: https://wiki.openstreetmap.org/wiki/University_of_Southampton 2: http://maps.southampton.ac.uk/
