Then maybe it would be best to have an abstract song folderish content type
which *only* contains the metadata, and contained within this folder you
could have the actual audio and notation files.

That's strange - I thought for sure that I replied to the list as well. I'm
pretty sure I did because otherwise you couldn't have gotten my mail. When I
sent it to your address, I got this msg back:

Nothing about CMF?  Archetypes is a relatively new thing, so it wouldn't be
in the Zope book. Here are a few links where you can read more:

Well, if you have it in postscript, you can convert it to PNG or PDF.

This sounds like a perfect use case for using Archetypes, because you can
define some BaseSchema (all the metadata about the song which is common to
the audio and notation files - song title, composer, etc.)

Then the audio and notation files could inherit these properties, so you
wouldn't have to add them again. You would only have to add the metadata
that is specific to the audio file (when it was recorded, who was it
performed by, etc.) and notation file.

Yes, I get overwhelmed sometimes too. There is a lot to learn with
Zope/CMF/Plone/Python, but once you get a handle on it, it starts to come
