This is a follow-up to my article about file format access tools and Lucene Tika.

More free open-source packages: Charlie Hull directed me to a file converters listed in the Omega overview, part of the Xapian project. Presumably, this lists packages that they've tested for quality.

The Omega overview, I've added links to the packages
