While we are pleased with the current status of Mi vaMi, one big item on our agenda is better resolution of ambiguous Tannaim and Amoraim. There are several Tannaim and Amoraim who bear the same name. There are four Amoraim who go by "Rav Kahana", in the first, second, third, and fifth-sixth generation. There is Rabbi Yehuda the Tanna, and Rav Yehuda the Amora. There is Rabbi Yitzchak bar Avdimi, the fifth generation Tanna, and Rav Yitzchak bar Avdimi, the third generation Amora. Is it Ravina I, or his nephew Ravina II? How do we distinguish between them? Right now, we often don't. Most names are not ambiguous, because
Rabbi Eleazar ben Shamua or ben Pedas?
