In this episode, host Karsten Hohage speaks with Simon Heimler (SAP) about Open Resource Discovery (ORD) – a protocol that allows applications and services to self-describe their exposed resources and capabilities. Simon explains in more detail what ORD is, how it’s used and where at SAP we already use ORD or plan to use it in the future. As the platform is an open standard by SAP geared towards the SAP ecosystem, how do we ensure a correct adoption of ORD at SAP? And how can it be helpful for individuals outside of SAP?

Clare explains how collaborative, community-driven approaches to open-source development at universities result in greater knowledge sharing, but also what the academia-specific challenges to open approaches are. This episode will help you gain insight into the evolving open source landscape in academia and how it differs from other parts of the OSS ecosystem.

In this episode, our host Karsten Hohage talks to Powen Shiah and Mirko Swillus about the Sovereign Tech Fund. Established in 2022, it focuses on critical infrastructure in the public interest with the goal of supporting development, improvement, and maintenance of open-source components in digital infrastructure. The funding comes from the German Federal Ministry for Economic Affairs and Climate Action (Bundesministerium für Wirtschaft und Klimaschutz), as investing in digital commons strengthens innovation, economic competition, and democracy.

In this episode, our host Karsten Hohage talks to Max Mehl and Sebastian Wolf about Software Bills of Materials or SBOMs. An SBOM is a detailed record of all components within a software application, including open-source libraries, third-party dependencies and licenses. Max and Sebastian discuss the importance of SBOMs as well as some challenges and unanswered questions of the state of the art. They also speak with Karsten about SBOMs within SAP and Deutsche Bahn and the importance of SBOMs when it comes to open source.

In this episode, our host Karsten Hohage talks to Thomas Barber about project “Foxhound”, an SAP-maintained fork of Firefox (the web browser) that is designed to detect security vulnerabilities in websites. Thomas discusses the history of “Foxhound”, how and why it was created, and its journey to becoming an open-source project. He talks about the importance of the collaborations that made Foxhound successful and about some of the challenges that it has faced along the way.
