I would like to clarify once again that I really do want to attribute OSM. But it's damn difficult for me to find out under which license my work falls.
I know lots of people, loading OSM tiles in QGIS and draw stuff on it. So I'm pretty confused that there aren't any guidelines discussed.

No, the shapefile will be used for further geoprocessing: selection of POI, which are non-free, but fall into the border I've digitized upon the OSM background map.

Would you recommend
1. to use another datasource as background map or
2. draw all borders on an OSM extract once again?

Since neither the drawing, nor my digitalization uses OSM data, I'm really asking myself if it's not a trivial act at all?
Wouldn't "Drawn on OSM tiles in CC-BY-SA 2.0, based on OSM data in ODbL" be enough as attribution?
