OK, I've periodically brought this issue up casually, but I'm wondering if anyone has any concrete suggestions. I am working on an easy-to-use schema that is based more-or-less on MODS. However, I still don't understand how in MODS to distinguish between: - an interview broadcast on a radio, and a one-on-one private interview - a play, and the performance of the play - a speech text, and a speech performance Is there something missing in MODS to fully support this? Maybe an "event" typeOfResource value? Something else? Bruce
