The international Convention on the Rights of Persons with Disabilities enters into force May 3, 2008. Among the principles are full and effective participation and inclusion in society; equality of opportunity; and accessibility (Article 3). The definition of communication includes accessible information and communication technology. A purpose of the treaty is to promote universal design in the development of standards and guidelines (Article 4); and to ensure that laws protecting intellectual property rights do not constitute an unreasonable or discriminatory barrier to access by persons with disabilities to cultural materials (Article 30). Articles 9 and 21 detail some of these rights:
