The interTwin Open Source Community is a collaborative group dedicated to the design, development, and maintenance of the Digital Twin Engine (DTE) code base, as part of the interTwin project, which aims to co-design and prototype an interdisciplinary Digital Twin Engine. This community brings together Digital Twin (DT) application developers, users, and operators to create interoperable DT solutions for scientific applications across various disciplines. The primary objective is to develop a shared platform that supports advanced AI workflows, Earth observation processes, physics and hydrological models, and more, following open standards to enable broad accessibility and integration across research domains.
The interTwin community is hosted on GitHub, where it currently manages 44 repositories (42 public and 2 private), supported by 64 collaborators, including both internal and external contributors, with an average of 2 to 14 active contributors per repository. Although contributions are open to everyone, new members must be invited by an existing community member. Contributions include code development, documentation, bug reporting, testing, issue management, project and release management, and community support and engagement.
The project operates under several open source licenses, including the MIT License, Apache License 2.0, and GNU General Public License v3.0, and has a code of conduct in place to ensure respectful and constructive collaboration.
Currently, the community has two owners, while the remaining participants hold member roles. The specific roles, responsibilities, and the governance and decision-making processes are under discussion and will be fully defined in the last year of the project. The same is true for the long-term sustainability strategies for the community and its projects, which are currently being formed and will be finalised before the end of the project.
