Open M-SDL
Measurable Scenario Description Language –
The Basis of ASAM’s OpenSCENARIO 2.0 Standard
Home » Open Language
M-SDL is an open, human-readable, high-level language that simplifies the capture, reuse, and sharing of scenarios and easily specifies any mix of scenarios and operating conditions to identify previously unknowns and edge cases. It also allows to monitor and measure the coverage of autonomous functionality critical to proving ADAS & AV safety, independently of test and testing platforms. The language is used by tool vendors, suppliers and developers in the ADAS & AV development space. M-SDL was chosen as the concept demonstrator and later adopted as the basis for ASAM’s OpenSCENARIO 2.0.
Following ASAM’s OpenSCENARIO 2.0 Standard publication announcement, Foretellix suspended the development of M-SDL to support the industry transition to OSC2. There are no plans to release other versions of the M-SDL.


M-SDL was made open, in order to enable the
ADAS & Autonomous Vehicle community to achieve ‘measurable safety’.
