Many ways in which the different cultures of groups and societies find expression. These cultural expressions are passed on within and among groups and societies, and from generation to generation. Cultural diversity, however, is evident not only in the varied ways in which cultural heritage is expressed, augmented and transmitted but also in the different modes of artistic creation, production, dissemination, distribution and enjoyment, whatever the means and technologies that are used.
