DiskLibrary is a nice app that can catalog your CD or DVD media. I’ve got about 400 discs in it which makes it my slowest app to load. But it’s handy to be able to easily find your files.
It exports the catalog as an xml file- a very large xml file. In time I’ll write something to parse it.

Gnome Catalog
There were several options in this category but the one that seems to be under recent development is Gnome Catalog. It supports categorization and ratings.
