The MODEVAR workshop is planned as a full day event at Tuesday, September 29th, 2026 in A Limassol, Cyprus. In the current edition, we invite discussion within the community to discover more ideas on improving UVL or variability modeling in general. Additionally, we provide a UVL tutorial to invite participants for trying out the latest capabilities of UVL. Using this tutorial, we want to gather feedback and future requirements for improving UVL capabilities.
