the not-very-helpful-for-you-but-philosophically-correct answer. any
and all information is good. there is no definitive list of info that
needs to be added. this is open-source and you're unpaid, so all info
is gratefully received. also, the map will never be complete, there
will always be changes, additions, etc.
the more-theoretically-helpful-but-possibly-not-helpful-in-reality-answer
if you cover all the features on the wiki at:
http://wiki.openstreetmap.org/index.php/Map_Features
you will have done everything possible to populate the map. and have
no life outside OSM
the answer i use for myself (in order of importance):
roads/railways;
footpaths/cycleways;
parks and other large areas of single-use land;
public and semi-public amenities (churches, post offices, town halls,
rail/bus stations, sports stadia, car parks, schools, playgrounds);
private, widely used amenities (supermarkets, pubs, chemists, petrol stations);
other notable physical features (bridges, car parks, railway level
crossings, power stations, triangulation points, peaks, lakes)
and then, time-permitting (usually not, unless it's somewhere i visit
a lot), any other items on the list of features
these are loosely based on the theory that most people will use OSM to
get from one (Street) location to another, and that large structures
by the side of the road/path help with finding location. after that, i
try to pick the things that people use the most and will search for
the most useful answer: think what you and others like you want the
map for. then, it depends on how much of your time you want to
dedicate; personally, the first time i go somewhere, i hit the most
important features to me, as listed above. if i go again, i add more
and more for each visit. i want to map everything, but i don't want to
spend my whole life noting every building, shop, track, etc.
sorry, that's not really answered your question directly, but i don't
think there is a definitive answer
