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 2022 edition:
Managing Open Source software and fulfilling their license obligations efficiently requires automated tools. This is evident if one considers that a single project may be comprised of a large number of differently licensed components, and already the source code of the Linux kernel alone contains more than 20,000 copyright notices that need to be made available when conveying the software in binary form. A number of tools exist to assist when creating such material and when managing projects of various sizes. In the basic lecture of the upcoming March COOL edition Caren Kresse of OSADL will give an overview of these tools and explain their advantages and drawbacks. Some newer tools will also be covered but even this will be restricted to analysis of source code. A completely different story comes into play when binary code instead of source code is going to be analyzed. This may be necessary when products are inspected that contain software in binary form and need to be checked for correct licensing when redistributed. Analyzing binary code is much more of a challenge compared to source code and only recently have appropriate tools been made available for this purpose. One of them is Armijn Hemel's analysis tool BANG. OSADL is very grateful that Armijn again accepted the invitation to speak at a COOL event and, in the advanced lecture, will present details how to use BANG and how to interpret results obtained with this tool.
Recommended audience COOL March 2022 edition:
Open Source officers, software developers and system integrators, internal legal department, external legal advisors, purchase department employees who deal with Open Source software, employees of QA departments, etc.
About the speakers of the COOL March 2022 edition:
- Caren Kresse: 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 Docker Base Image.
- Armijn Hemel MSc: Armijn is the owner of Tjaldur Software Governance Solutions. He is an active researcher of and internationally recognized expert in Open Source license compliance and supply chain management.
