SIGs are community-driven collaboration forums focused on specific industries, technologies, or emerging areas of interest. They provide a space for members to share expertise, discuss challenges, exchange best practices, and align on real-world use cases across the safety-critical ecosystem. As ELISA expands into new domains, SIGs such as the Railways SIG and Space Grade Linux SIG help bring together industry experts and open source communities to address the unique needs and opportunities within those sectors.
Space Grade Linux SIG
Learn More
The goal of the group is to advance space technology innovation and competitiveness by developing a common Linux distribution that can be used in space applications, ready for the challenges of deep space, often long lifespan robotic or human-based missions. The nature of space missions brings many challenges; from development to deployment there are multiple considerations that need to be considered. Furthermore, this group is the initial step towards creating an ecosystem of supported platforms and a community that benefits from them, and also from the open source nature of the project.
Railways SIG

The Railways SIG focuses on aligning Linux development with rail industry standards, addressing everything from signaling and control systems to automated train operations. It aims to inform all railway stakeholders about the extensive capabilities that open source already offers in the safety domain. At the same time, it represents their specific needs to the ELISA community, ensuring that future developments continue to benefit railway systems and infrastructure worldwide.
Lighthouse OSS Special Interest Group
Learn More
The Lighthouse OSS Special Interest Group (SIG) brings together contributors from across the open source ecosystem to identify, evaluate, and document established open source development practices that support software quality. Drawing on research literature, existing standards, public best-practice frameworks, and evidence observed in open source projects, the SIG is developing a checklist and assessment guide to help users understand which development practices a project defines, how they are applied, what observable evidence is available, and where gaps may remain.
By making open source development practices and their supporting evidence more visible, the SIG aims to support informed assessment, adoption, and improvement of open source software across industries. This work may be particularly valuable in regulated or critical domains, where transparent evidence concerning software quality (including safety- and security-relevant practices) can support assurance activities.
In the longer term, the SIG aims to use this community-developed work to lay the foundations for a standard on open source development best practices. The group welcomes contributors interested in open source quality, assessment methods, and the possible future standardization of open source best practices.
