Hi Dave,

Well, actually it's close to a decade old. But it *is* still
only a start. ;)

Right now, you can just mail me the spectra and any information
you have on them.  I'd prefer them as column data of energy,
xmu, and any other channels you might have (i0, a reference
foil, etc), and in individual files rather than a spreadsheet.

I think it's definitely worth looking into re-implementing this
Model Data database.  Looking at the code and data I have, I
think this is definitely possible, and it does seem like it is
time to revisit this idea.

I think there are a few important features for such a database:
 -  through-the-web uploading and annotaing of data, probably
    after 'logging on' (as with the FAQ).
 -  simple visualization, even if just plotting mu(E).
 -  link to crystallographic info.  Say, an atoms.inp.
 -  easy searching.
 -  either "user comments" added by others (aka Amazon-style 
    reviews) or some way to indicate that the data is "good".

Does anyone else have thoughts or suggestions for such a
database of model compound data?  Is a database like this 
worth doing?
