Actually, there are also extended attributes. It's a bad idea to use EAs directly for storage of irreproducible information, since many backup and copy tools won't preserve them. However, you can use EAs to associate some unique ID with the file to make it easy to track. This is done, for example, by Beagle. Make the ID something like the file's SHA1, and you can easily recover from EA loss (as long as no one changed the file beyond your software's back).
