stiEF – A textual scenario description language
summary
Audi's textual DSL stiEF is implemented in MPS and embeds a multilingual grammar so the same scenario swaps between English, German and Chinese while keeping visualization synchronized. It models five Pegasus layers, supports country-specific road markings for Germany/US/China, and exports to OpenDrive/OpenSCENARIO plus Word, Excel, PNG and JSON. The editor toggles abstract→logical→concrete levels with parameter ranges that the cloud generator expands into many randomized concrete tests. Prototype visualization and generators work; limitations include restricted free-text, ongoing parking/roundabout support and tooling/legal rollout.
