Trialog/EVIDEN guidance on using Digital Twin Reference Architecture and contributions to CEI Architecture considerations

Antonio Kung (Trialog) and Lara Lopez (EVIDEN) both attended the plenary meeting of ISO/IEC JTC1/SC41 in November 2025 in Berlin. JTC 1 is the Joint Technical Committee of ISO and IEC focussing on Information Technology, and SC41 is the Subcommittee dedicated to “Internet of Things and digital twin”. During this meeting, Antonio Kung gave a lecture to guide the use of the ISO/IEC 30 188 standard on Digital Twin Reference Architecture, which recommends the creation of an Hourglass model to describe stakeholders, capabilities, and relevant standards at the start of a Digital Twin project.

Moreover, Lara Lopez and Antonio Kung, as editors, contributed to the JTC 1/SC 41-22 Preliminary Work Item (PWI) they are currently co-editing on the topic of “Architecture considerations for IoT, edge and cloud”. This future standard aims at providing a technical overview of the architecture in the IoT, edge, and cloud with the goal of promoting O-CEI results. The contribution is based on blueprint constructions as shown in the figure.
