How to name and conceive audio for an archive

Questions Questions

start arrising:

Example: Simon Pope's recording has three parts

1) introduction under the arch (just before the minidisc died)
2) part outside - further explanation
3) quite noisy but understandable part in the cafeteria - where people do their charade and there is the talk about rights

So, my questions are, do I keep the three parts?
How do I name them?
Do I keep comments about how cold it is?
What to do with the introductions to the talks, for example the sunday?
because, basically, with the audio we have we can reconstruct the festival (so, really link it to the time structure)
Do I try to make seperate audiofiles from those introductions - if their quality is ok?
How to name them for the database?
