Plumbing roughing

Can anyone tell me what “roughing” is in relation to plumbing? My house, which I purchased last year, has an open permit on it from 2003 which I am trying to resolve. The DOB site says (under the plumbing inspection info) “first floor rear roughing OK, basement roughin OK” but I don’t understand what this means. Any adive would be appreciated.
