As interest rises, we see prospects for smarter and easier integration of various technologies from multiple vendors related to IoT devices and Web services.</p>

             <li>We also confirmed that it would be very important to consider inclusive design including accessibility, privacy, security, and internationalization. Smart City applications are tightly related to the people who live in cities. We want Smart City technology to have a positive impact on their lives and want to avoid unintended negative consequences.</li>

              <p>During the discussions at the TPAC 2022 breakout, it was identified “Digital Twins” would be the key concept for Smart Cities services, and we should start with clarifying the use cases and requirements for “Digital Twins” first.</p>
 
              <p>Note that there are various definitions for "Digital Twins" all over the world. However, given the collaborative discussion with ITU-T SG20 and ISO/IEC JTC 1/WG11 starting with the Smart Cities Workshop, we'd like to use the following basic definition from "<a href="https://www.itu.int/ITU-T/workprog/wp_item.aspx?isn=18456">Y.4605</a>" as the starting point.</p>
