Can you give me a reference for the statement that CCBYSA and ODBL are compatible? I understand that they have certain similarities, but I want to understand if I can take ODBL content and relicense it under CCBYSA and the other way around.
Probably it isn't allowed to import CCBYSA sources into ODbL either. Pretty complicated. Thats why in OpenStreetMap all useres have been asked to agree to the licence change from CCBYSA to ODbL.
