What you now hold in your hands is the first annual report of the GNOME Foundation, at the end of what has been an eventful year for us. Each year brings its challenges and rewards for the members of this global project. This year, many of our biggest challenges are in the legal arena. European countries have been passing laws to conform with the European Union Copyright Directive, and some, including France, have brought into law provisions which we as software developers find it hard to understand, but which appear to make much of what we do illegal. We have found our- selves in the center of patent wars as bigger companies jockey for position with offerings based on our hard work. And we are scratching our heads trying to figure out how to deal with the constraints of DRM and patents in multimedia, while still offering our users access to their media files.
