We are happy to announce the live video recording of a workshop that gives a comprehensive overview of the fundamentals of the extensible, web-based modeling platform Oryx, which consists of a model editor and a repository to store and manage models. The presentation gives insight into the architecture of Oryx and explains how to design new modeling languages (via stencil sets) and develop new features (via plugins). The video can be seen at Tele-TASK and slides are available here (pdf).
