To create a new OpenStreetMap::Node object:

node = OpenStreetMap::Node.new(:id => "123", :lat => "52.2", :lon => "13.4", :changeset => "12", :user => "fred", :uid => "123", :visible => true, :timestamp => "2005-07-30T14:27:12+01:00")

To get a node from the API:

node = OpenStreetMap::Node.find(17)
