rpm-python and metadata stuff

Hi all,
 I've been working on some code to deal with generating and importing
metadata. Many of y'all have already heard about this stuff but I wanted
some more input, if possible, from others.

go here:
http://linux.duke.edu/metadata/generate/

that's the code that generates the metadata from a dir of rpms.

then go here:
http://linux.duke.edu/metadata/import/

that's the code that imports the metadata from the format generated
above.

Give it a look over, test it out, see if you think it sucks, etc etc.

I'd like input about it, suggestions, whatever.
Thanks
