Second W3C Workshop on the Web of Things
The Open Web to Challenge IoT Fragmentation

3-5 June 2019, Munich, Germany

The workshop is free, although you will need to submit an brief expression of interest or a longer position paper. See How to participate.

Call for Participation


Interoperability of devices and services for the Internet of Things (IoT) with cloud platforms and services at a worldwide scale is a huge challenge.

Recent developments in electronics have dramatically reduced the cost for devices functioning as tags, sensors, and actuators for the physical environment, i.e., the Internet of Things. The market potential for IoT devices and services is currently held back by fragmentation due to a plethora of communication technologies and the lack of a common approach to combining devices and services across different protocols, domains, and standards. There is no a common way to describe and combine semantic behavior.

RESTful Web technologies have become very important in recent years, such as HTTP, JSON, and JavaScript combined with open standards for data formats, interface definitions, and access control.

The mission of the Web of Things activities is to counter the fragmentation of the Internet of Things by forming a Web-based abstraction layer capable of interconnecting existing IoT platforms, devices, and cloud services and complementing available standards. Baseline specifications have been developed by the Web of Things Working Group during the last two years to define an architecture and a common format for describing devices and services.

There is a wide range of application domains including the following:

To achieve the goal for cross-platform interoperability, the W3C Web of Things Working Group has finalized a first set of standardized building blocks. They are based upon rich metadata that describes the data and interaction models exposed to applications, and the communications and security requirements for platforms to communicate effectively. During the course of the Web of Things standardization activities, the following specifications were created:

A W3C Workshop is now planned for mid 2019 to disseminate the findings and discuss the way forward with a wider set of stakeholders. To unlock the potential of an open ecosystem and open markets, the workshop will discuss how to reduce fragmentation of the IoT landscape and the future direction of the open W3C WoT standardization. A focus is on exposing and consuming services across specific IoT technologies to enable new use cases, such as common monitoring and control of assets from multiple vendors, interconnecting different application domains, and building digital twins of physical devices.

The workshop is free, although you will need to submit a brief expression of interest or a longer position paper. See How to participate.

What is W3C?

W3C is a voluntary standards consortium that convenes companies and communities to help structure productive discussions around existing and emerging technologies, and offers a Royalty-Free patent framework for Web Recommendations. W3C develops work based on the priorities of our members and our community.
