This is an “outcome” webinar from the OpenChain and Friends event in Stuttgart, Germany, in April 2025. Our focus was on recent advances in the open source and open data AboutCode stack for licensing and security compliance. Our speaker was a good friend of the OpenChain Project, and the founder of AboutCode, Philippe Ombredanne.
This event is part of the overarching OpenChain Project Webinar Series. Our series highlights knowledge from throughout the global OpenChain eco-system. Participants are discussing approaches, processes and activities from their experience, providing a free service to increase shared knowledge in the supply chain. Our goal, as always, is to increase trust and therefore efficiency. No registration or costs involved. This is user companies producing great informative content for their peers.
Oscar Goñi (Quique) discussed research around LLM generated code and the potential for risks associated with open source license compliance. This event looked at source code similarity detection via open source tooling.
Watch the Webinar:
Abstract:
Oscar Goñi (Quique) has investigated source code similarity detection in Large Language Model (LLM) out-puts using the SCANOSS platform. While recent research has identified concerns regarding LLMs generating code that closely resembles their training data, the full extent of this similarity across the broader open-source ecosystem remained unexplored. Quique will describe during this talk his findings, which indicate that code similarity in LLM outputs may be more prevalent than previously indicated when evaluated against a broader open-source code base. At the same time, Quique will describe how this study contributes to the ongoing discussion of LLM-generated code’s originality and its implications for software licensing compliance, while validating the effectiveness of lightweight similarity detection algorithms as preliminary indicators for more comprehensive analysis. Finally, a Q&A session hopefully will provide participants some light of the implications of the study and to Quique about next steps in his research.

This is part of the OpenChain and Friends: Stuttgart – Follow-Up Webinar Series:
Once upon a time, researchers at Ericsson developed Erlang/OTP, a programming language for the telecom industry. 39 years later, Erlang/OTP is used by the telecom, messaging, banking, and even game industry. Not only that, new languages were created and run on top of the Erlang BEAM virtual machine: Elixir, now a well-established language, and Gleam, the newest addition.
The proliferation of libraries and languages powering the BEAM ecosystem led to the creation of the Erlang Ecosystem Foundation (EFF),a foundation that caters for the BEAM ecosystem.
Today, 39 years from the creation of Erlang, it is not an easy task to categorise and be compliant with the more than 13000 (total) files that make up Erlang, Elixir, and Gleam. Yet, Erlang and Elixir are OpenChain compliant, and Gleam compliance is work in progress.
What steps took EEF towards making sure that Erlang, Elixir, and Gleam comply with the different licenses and copyrights?
This presentation features the collaboration between the Erlang/OTP team (Ericsson) and the Erlang Ecosystem Foundation (EEF), and the steps taken, and experience of using ORT as a crucial part of the EEF Ecosystem.
Our Speaker:
My name is Kiko Fernandez-Reyes and I work as a software engineer in the OTP team, building and improving the Erlang programming language at Ericsson. Before that, I was a backend software engineer at Klarna.
Before Klarna, (in 2014) I did my Ph.D. at Uppsala University where I developed concurrent and parallel programming languages for our research compiler. Among them, I developed typed-based optimisations for future-based programming languages and a capability-based dynamic language design that maintains data-race freedom and satisfies the gradual guarantee.
Experience: I have industrial experience with Haskell, Erlang, Python, among others and deployment languages and technologies, ranging from AWS to Ansible. During my research I have used heavily Haskell and C, and some Scala. I was the main lecturer of the course Advanced Software Design, where I taught object-oriented design ~80 master students.
My work has received the following awards: – Distinguished Artifact Award at Software Language Engineering (SLE), 2019 – Distinguished Artifact Award at European Conference in Object-oriented Programming (ECOOP), 2019 – Best Paper Award at International Federated Conference on Distributed Computing Techniques (DisCoTec), 2018 – Best Paper Award at International Conference on Coordination Models and Languages (COORDINATION), 2018
Interests: I am interested in type systems, programming languages, functional programming, compilers, and different logics. I promote open source technology, writing regularly in opensource.com. I also promote gender equality through the ACM-W student chapter at Uppsala University.

Open source software providers are facing a triple threat: tightening US and EU regulations, rising IP litigation, and the risks introduced by Gen AI. Soon, your board—and your customers and suppliers— might be asking that you have specific insurance that actually covers OSS-related liabilities. But, does such insurance exist? Does it work? And how should it work?
Historically, insurers have struggled to grasp OSS risks, offering inadequate or unclear coverage. Now, a new wave of insurance solutions is emerging, informed by OpenChain standards and best practices.

When walking into a shop, there’s a lot of choice for electronic devices like WiFi routers, IP cameras, and more. Many devices are identical, or nearly so, as they come from the same manufacturer or use the same chip and code from the chipset manufacturer.
CVEs, however, often focus on individual devices rather than classes of similar devices, leaving many vulnerable ones unreported. For example, CVE-2006-2560 and CVE-2006-2561 describe the same vulnerability on devices from different vendors—likely from the same ODM. Many more devices with the same vulnerabilities are overlooked, possibly giving a false sense that only the listed devices are at risk.
Information about device hardware, such as the ODM or chipset used, isn’t easily accessible, as companies rarely disclose this. Fortunately, a wealth of data has been crowd-sourced globally via various wikis. However, this information is hard to reuse outside those specific platforms.
This is where DeviceCode comes in: it unlocks and cleans data from various wikis (as not all users input data correctly or consistently) and integrates it with other sources. This makes it possible to query by chipset, manufacturer, ODM, and even installed software. It helps answer questions like, “Which other devices are similar to a known vulnerable device?” enabling security researchers to identify additional vulnerable devices.

We had an insightful session with Dawn Foster on sustaining OSS projects and communities over the long-term. The CHAOSS project has been creating a series of MIT-licensed Practitioner Guides focused on improving the sustainability of our software and communities. The guides are designed to make it easier for people to draw meaningful and actionable insights using community metrics, even when those people do not necessarily have a deep background in data analysis or much experience working within OSS communities.
This talk identified several categories of metrics from the Practitioner Guide Series, including responsiveness, contributor sustainability, organizational participation, and security. It covered not just how to interpret the metrics, but also on providing ideas for improving in areas identified using the metrics. The audience walks away with a better understanding of how to use metrics to proactively improve the long-term sustainability of their OSS projects and communities.

We have been doing source level license scans for Linux Foundation (LF) projects for a long time including generating SPDX formatted files, but what about SBOMs that can meet (and exceed) the government minimum specification? Here at the LF, we are now leveraging our existing scanning capabilities to generate SBOMs for these same critical open source projects.
In the LF spirit, we are using existing open source tools to scan project dependencies to produce an SBOM that meets the minimum spec. We are also producing dependency level license data to complement our source level scans. In the near future we will be combining these to produce a grand unified SBOM that will meet a newly defined LF minimum specification for SBOMs.
We will talk about our process to generate these SBOMs, the challenges we faced, our future plans, and share more about how you can make use of these for the projects you care about most.

When we think about Software Build of Materials, we are looking at what might be a multi-dimensional space consisting of hierarchy, linking, modification, export restrictions, security vulnerabilities, distribution type, versions, etc. Care must be taken when setting up the SBOMs to both list the components used and to show how they are incorporated into your products. This webinar discusses how a visualization of such meta-information was implemented to display the relationships and potential risks in a quick and in easy-to-understand way. It was part of a research project funded by the Federal Ministry for Economic Affairs and Climate Protection (BMWi) and with the Bonn-Rhein-Sieg University of Applied Sciences and Bitsea.
