Passage 1 The development of the Information Society must be based on platforms of internationally interoperable technical standards, accessible for all, and technological innovation of ICTs, as well as systems to promote the exchange of knowledge at global, regional and sub-regional levels through any media. In this regard, in addition to enhancing people’s awareness of the advantages of using ICTs, reliable, advanced and appropriate ICT technologies and services infrastructure are required. // As a sharp increase in the volume of international and regional Internet traffic is anticipated, it is important to strengthen regional and international broadband network infrastructure by using new technologies to enhance network efficiency and provide the capacity to match the needs of the countries in the region. // Working towards open and flexible international and interoperable standards is an important issue for all countries so as to ensure that all can utilize the technology and associated content and services to their maximum potential. Development and deployment of open-source software should be encouraged, as appropriate, as should open standards for ICT networking. // In order to achieve affordable and universal access it is important to enable existing and new technologies to provide connectivity to all, in particular through institutions accessible to the public such as schools, libraries, post offices and multi-purpose community centers. Special attention should be paid to how ICTs can benefit the disadvantaged, through innovative initiatives. // High-quality access, attainable through broadband, has great potential to help better deliver essential services required to meet basic human needs through applications such as e-education and e-health, as well as e-business and other ICT applications. Also, new technologies, such as wireless and satellite networks can assist remote areas, including small island nations, to gain access to information and knowledge. // Linguistic and cultural diversity enriches the development of society by giving expression to a range of different values and ideas. It can facilitate the spread and use of information by presenting it in the language and cultural context most familiar to the user, thereby further encouraging the use of ICTs. // Promoting broadband networks in the Asia-Pacific region could not only support research, business and personal activities, but also help to preserve cultural diversity and indigenous knowledge and traditions. In this context, an effort should be made to support multilingual domain names, local content development, digital archives, diverse forms of digital media, content translation and adaptation. The development of standard and recognized character sets and language codes should also be supported. //(Excerpt from "The Tokyo Declaration—the Asia-Pacific perspective to the WSIS")
