Addresses within a University Campus

I'm just adding some postcodes to one of the Nottingham University campus sites and realise that the available Open Data for addresses within the campus means that the addresses don't fit neatly in existing OSM addressing schemas. I am sure this issue affects many large campus sites (Universities, Hospitals, Commercial sites).

Most, if not all buildings share the following address elements University of Nottingham, University Park, Nottingham NG7 2RD. The latter two are OK: one is addr:city, the addr:postcode, but the former is an organisation and the latter an area, which contains many named roads. I expect that there are other organisations sited on University Park (such as the Medical Research Council Institute of Hearing Research).

It is conceivable that one could treat "University Park" as a street name, but I would regard that as highly misleading. Therefore I would like to know :

Are there viable alternative approaches to mapping addresses on campus sites?

Note: this is an example of how addresses dont fit most people's preconceptions.

(I am aware of course about addr:full, but this question is aimed at finding ways of avoiding this cop-out).
