Tags
OSM Data Objects are described by Tags, which consists of a pair of values, a Key and a Value
Tagging is relatively flexible, created through a folkosomony. ● (Does the tag exist? No ? Create one and document it on the wiki !
● Found a Tag ? Add it to the object !
Systems of Tags● http://wiki.openstreetmap.org/wiki/Map_Features
What do I map ?
● Anything that Physically Exists (and is Permanent) !
