What is COOL?

COOL - Compact OSADL Online Lectures: Open Source meets Industry

  • COOL is an OSADL webinar series.
  • COOL takes place regularly once a month and covers new and state-of-the-art topics on Open Source software in industry, either on legal or on technical aspects.
  • COOL editions each consist of two lectures covering a special "Open Source meets industry" topic followed by a discussion round. The first "basic" lecture provides basic knowledge with regard to the respective topic and the second "advanced" lecture dives deeper into the topic and highlights special aspects. The discussion round gives all participants the possibility to ask questions and discuss with the respective speakers and the audience.
  • COOL speakers are OSADL experts on the one hand and external specialists on the other hand who kindly agreed to share their expert knowledge on the respective topic.
  • COOL is a virtual event. The lectures are held by live video streams. Speakers will be available for questions and discussion in a video conference which will take part subsequent to the live video streams.
  • COOL in general is designed to provide support how to best and compliantly use Open Source software in industry.

Description COOL March 2024 edition:

A major advantage of FOSS is the possibility to reuse existing components. Thus, it seems obvious to adopt the same strategy for FOSS compliance material in those areas where the required efforts are identical for all users of the software. This is precisely the basic idea behind the OSSelot project, which has set itself the goal of making curated license compliance material for frequently used software projects publicly available.

Establishing trust in the OSSelot project requires a consistently high quality of license compliance data. To achieve this, a standard curation process is needed. Although a large part of data curation can be automated with license scanners, manual review and sometimes correction of the scanner findings is indispensable. In the first presentation Caren Kresse, OSADL will demonstrate the data curation process in OSSelot. She will give some examples of commonly required corrections as well as show some findings that need more advanced investigation and legal interpretation.

In order to make OSSelot even more versatile and to be able to license even more complex embedded systems based on OSSelot documents, more packages need to be curated than can be provided by OSADL alone. Therefore, it is an important step for the scalability of the curation database to motivate external contributions to OSSelot. This addresses companies that already curate their own packages in isolation, but could do so in collaboration with OSSelot. The advantage is that the company can benefit from an external review and at the same time the OSSelot pool of curated software packages can grow - probably without significant additional effort for the contributing company.

"How to contribute to OSSelot" is the topic of the second presentation, which will also cover the expertise and tools needed to contribute to OSSelot. It will show what the contribution and review process might look like. This talk will be given by the maintainer and main contributor, Oliver Fendt. Astrid Spura, OSADL, will join him to share her experience with the OSSelot contribution and review process.

Recommended audience COOL March 2024 edition:

Open Source officers, software developers and engineers, system integrators, employees of internal legal departments, external legal advisors, purchase department employees who deal with Open Source software, employees of QA departments, etc.

About the speakers of the COOL March 2024 edition:

- Caren Kresse, OSADL: Caren Kresse holds a Master degree in Physics. Already during her studies she used and appreciated the large amount of Open Source software and she became acquainted with all aspects of Open Source communities. In particular, she specialized on legal aspects of conveying Open Source software and has been working on various aspects of Open Source license compliance with OSADL since 2018. Among others, Caren leads the OSADL Open Source Policy project and is deeply involved in the OSADL License Obligations Checklists project. Furthermore, she maintains the OSADL Container Base Image and the project page for the OSSelot curation database where she also contributes curated compliance data. Since 2024, she also serves on the OSADL board of directors.

- Oliver Fendt, Maintainer of the OSSelot project repository: Oliver Fendt studied telecommunication engineering. After the studies he started his career as a software developer at Siemens. He took several positions as a software developer and project leader. In 2003 he moved on to Siemens Corporate Technology (today it is called Siemens Technology) where he became responsible for Open Source license compliance. He has more than 21 years experience in Open Source software, its license conditions and how to comply with the different licenses. During this time, he kicked off several initiatives to reduce the cost of license compliance work. He has profound expertise in all areas of Open Source license compliance.

- Astrid Spura, OSADL: Astrid Spura joined OSADL in 2014 and has since then extended her knowledge of the legal and strategical aspects of Open Source software.
