DERIVATIVE WORK - A work based
upon one or more preexisting works, such as a translation,
musical arrangement, dramatization, fictionalization,
motion picture version, sound recording, art reproduction,
abridgment, condensation, or any other form in which
a work may be recast, transformed, or adapted. A work
consisting of editorial revisions, annotations, elaborations,
or other modifications which, as a whole, represent
an original work of authorship, is a 'derivative work'.
