Heavily used by various industries and services (including payments/commerce, media distribution, video conferencing, connected cars, etc.), the Web is becoming a promising platform for IoT interoperability. In the context of the current global sanitary context, there are great expectations for smarter and easier integration of various technologies from multiple vendors related to IoT devices and Web services. W3C organizes a W3C workshop on 25 June 2021 to discuss applications and use cases of W3C's Web of Things standards for smart city services.
