I have thought about building a vocabulary learning tool for learning Japanese on top of Apple Dictionary. My idea is simple: user collects dicitionary items and the tool offers lookup / spaced-repetition.
However, I'm concerned that the dictionary is copyrighted. Is there any precedent that says whether such a tool would be legal/illegal?
