[OSM-dev] Source and algorithms

[Vojtech Brtnik]

Hello everyone,

I must admit, that I am a bit lost on the openstreetmap homepage, so
maybe you can just forward me to appropriate places :)

For the purposes of my master thesis at Uni, I am looking for
documentation about OSM (OpenStreetMap). Is it avaiable to see
algorithm description and data representation that you use in OSM? Is
there any API, that one could use for a plugin or application using
OSM somehow?
Under what licence is OSM written - GPL?

Thanks,
PJ
