[OSM-talk-ie] tags for highways

[Caroline Lewis]

Hi - i am correcting in josm and am confused by the highway tags - in cork highways leading to houses were all tagged as tracks but in the kerry section there are residential, service, unclassified  and tracks 
which tag should i use and when?
also do i need to draw in buildings or should i just get highways/streams done?
its v. slow work!!!
thanks
