It seems that you want to translate some strings in the online editor called Potlatch2 … you cannot translate “Openstreetmap” because that isthe whole project. YOu can define one component of OSM like a special web GUI or an editor 
Have a look at http://wiki.openstreetmap.org/wiki/Potlatch_2 to find out how to get in development about it.
