Scope of the workshop

Nearly all Open Source licenses have a common set of license obligations that is to forward i) the license text, ii) a warranty disclaimer in favor of the original authors and iii) a list of copyright notices. In the good old days when software was developed by a small number of authors and there was only a small number of different licenses this was relatively easy to fulfill. These three documents could be handed over to the customer in print but could also easily be included into the software.

Today, however, there are software packages written by more than 10,000 contributors and including up to hundred and more different licenses. Even if someone underwent the enormous work to collect all this information manually, it would still include the risk that something was forgotten, and, unfortunately, even a single forgotten element of this information may already constitute a license infringement. Thus, the only solution is to use automated tools to extract this indispensable information from software. In addition, it is not sufficient to just use this tool once, but it must be integrated into a company's processes to provide continuous integration. Finally, even when all of this is achieved, the tool should still allow to supervise not only a single department of a company but all departments that require such tools in order to provide a synergistic effect. The latter clearly asks for a client server concept of such a tool and one of the best suitable tools for this purpose is FOSSology. Goal of the workshop is to make participants familiar with important features and relevant configurations of FOSSology and to learn how this tool can be integrated into everyday’s work.

An individually prepared FOSSology database on a dedicated server will be made available for every participant. In the morning of both workshop days  help desk sessions are offered, where participants can join in at any time for technical check-up and ensure proper access to server and database. The actual workshop sessions start at 1pm respectively on both days.

We are very pleased that Michael C. Jaeger, co-maintainer of the FOSSology project and co-lead of the Eclipse SW360 project, and Maximilian Huber, developer and supporter of the FOSSology and Eclipse SW360 projects accepted our invitation to contribute to the workshop as trainers and speakers.

Participants of the workshop should have basic knowledge of Open Source licensing. No particular experience with FOSSology is required.

Recommended audience

This workshop is recommended for anybody, who is interested, be it by personal or by professional reasons, in learning the theory, the background and the practice of software scanning in order to obtain license compliance. This comprises but is not limited to software developers, project managers, Open Source officers, legal consultants, employees of purchase departments, etc.

Participants of the workshop should have basic knowledge of Open Source licensing. No particular experience with FOSSology is required.

Access to FOSSology - Recommended equipment

Participants will get access to an individual FOSSology server instance that can be operated from any commonly used Web browser. To ensure that every participant can connect to the FOSSology server and database without any technical hassle during the workshop, help desks are offered in the mornings of the workshop days and we recommend to join in at least on the first day at any time between 10am and 12pm.
