Excel file to Dublin Core?

Hello all,

I have an excel file that I need to map to Dublin Core. I can think of
a number of ways to do this, but was wondering if anyone else who has
done it has a suggestion before I dust off my old sed/awk skills or
otherwise reinvent the wheel. I looked at Terry Reese's MarcEdit and I
probably can use that, but it looks like I'd have to intermediately
convert it to MARC. Either a windows-based program or *nix tool is
fine.
