With BIXTEP, you can use the three pre-defined content types notes, excerpts and sources (version 0.1) or you can define your own content types (> version 0.2). It's easy to use BIXTEP as a catalog for your CDs, DVDs, as an address book or anything else. It's up to you and the changes you make to the configuration file.

A content type consists of a unique typename and a fieldset.
