handling metadata with multiple values

[Ray Plante]

Hi Gretchen,

Hmm, I thought you guys didn't like the list elements (or at least Wil 
didn't).

Could you expand on this a little more about how it would help?  That is, 
how do you envision extracting values to test against a query?  (e.g. will 
you extract into a database first?  using an ots tool or something custom 
written on top of, say, DOM & JDBC?)

There is no difference in the information stored in the two approaches.  
So the differences are in how you access the data programmaticly and how 
it looks.  (Any others?)  My discussion addressed the programmatic issues.  
I don't want to discount the ascethetics, but I think it is important to 
understand which kind of issue we're talking about.

cheers,
Ray
