Cedric Brun, Obeo's CEO, is invited to open the 19th edition of the International Conference on Software Language Engineering (SLE) as a keynote speaker, on July 2nd, in Rennes, France. This conference brings together researchers from different areas united by their common interest in the creation, capture, and tooling of software languages. In his keynote, Cédric will reflect on two decades of building and deploying modeling languages in the real world. The conclusion is simple. The problem was never language itself. It was everything around it: user experience, integration into workflows, and the ability for teams to share and evolve a language over time. The shift to web-based platforms such as Sirius Web and SysON changes the game. Not just new technology. A new constraint. Languages must be collaborative. Accessible. Alive. No longer reserved for experts. The future of modeling is not less language. It is more language: better tooled, more collaborative, and clo...
