Nextls is a console application that keeps track of your music collection using a MySQL database to store information such as length, bitrate, metadata, and where on the hard drive it is located. When Nextls is launched, it will figure out any changes done since the previous run and update the database accordingly. The database is very simple to work with, and there also exists a sister project in Nx2 that will allow you to take your database online and stream your music from a Web browser.
DatabaseToUML reverse engineers a database schema from an existing relational JDBC database. Tables and fields are reversed to classes and attributes, constraints are reversed to association, and tables composed only of foreign keys are converted to many-to-many associations. The main idea is to reuse the reversed model in a generator, taking UML2.x (EMF XMI 2.0/2.1) models as input.
