An OSM '''way''' is also used to respresent a river, the boundaries of a country, or even a building. If a '''way''' is closed, i.e. if the last node is the same as  the first node, it is also called an '''area'''.

- * [[Image(source:/trunk/images/data/relation.png)]] - a '''relation''' is an sequence of other objects, for instance a sequence of '''ways''' (representing road segments) and '''nodes''' (representing bus stops) which represent a bus route. Each object participating in a '''relation''' can be assigend a '''role''', for instance `stop` for a bus stop in the bus route, or `forward` for a road segmente which is part of the bus route from the start to the terminal station.

-A '''tag''' is a name/value pair assigend to an object. Tags are used to describe an object in detail. If we write `foo`=`bar` we mean ''The tag with key foo is assigned the value bar''. Here are two examples:

Whenever possible you are adviced to stick to these tags because map renderers, routing engines, and other pieces of software rely on them.
