The heterogeneity of protocols and platforms is one of the main interoperability problems of the Internet of Things. The W3C Web of Things addresses this challenge with a set of standards; WORMS met the need to offer application developers a complete, operational reference model for building systems that comply with those standards.
The objectives of the project were:
- To provide developers worldwide with a reference model for building any enterprise system compliant with the Web of Things.
- To facilitate interoperability between systems and applications that work with IoT devices from different manufacturers.
- To reduce maintenance costs and development times for applications that work with IoT devices.
- To expand the ecosystem of digital enabling companies capable of offering Web of Things-based solutions for industrial digitization.
The areas around which WORMS was structured were:
- Complete runtime environment: a fully functional W3C Web of Things runtime environment, with protocol bindings for HTTP, CoAP, WebSockets, and MQTT.
- Two versions of the implementation: one for devices with greater processing capacity and another for devices with very limited capacity, in order to cover the widest possible variety of IoT systems.
- Documentation for the community: definition and usage guide for the reference implementation, conceived as a meeting point for the developer community and a practical complement to the official W3C documentation.
CTIC developed the project, whose results led to a scientific publication in the journal Computer Communications and to an open-source framework.
