export exif to another program

Does anyone have a program that will export EXIF and IPTC data from the LR Catalog to another program.  Ideally, I want to import it into a FileMaker database.  Short of that into another SQLite database will be fine.

Here's what I want to do.  I want to track print sales and stock licenses for images that I market (about a third of my total catalog).  I don't want to have to manually build records in the database but want to automate this by reading the data from the LR catalog in importing it.

If there is no plug-in, I know that any program that can read SQLite can read the catalog.  So does anyone have a stand-alone program to capture the data?

Thanks
