ASAM OpenSCENARIO is an XML-based standard used to describe traffic situations in ADAS development. Use our library to read and validate ASAM OpenSCENARIO formats. Start with your simulator or editor and embed our library into your application.

100% compliant with the ASAM OpenSCENARIO 1.X standard

The OpenSCENARIO API is an open source project initiated by RA Consulting and made available under the Apache License 2.0. It provides read and write access to OpenSCENARIO and is 100% compliant with the ASAM OpenSCENARIO 1.2 standard. The library is available for the C++ and Java platforms.

Main features

Validate your OpenSCENARIO files

An executable checker gives accurate warnings and errors in a row and column based file location. It displays errors as well as used and no longer supported elements (deprecated). With custom rules you can extend the checks and validate all files compatible with the standard 1.0, 1.1. and 1.2 versions.

Browse and edit descriptions

An application programming interface (API) guides you easily through the elements of a description. A write interface allows you to modify the elements and then save them in ASAM OpenSCENARIO format.

Integrate the component into your application

Our component is e.g. part of OpenPass Framework for the simulation of traffic situations in the ADAS environment. There, the component is integrated to read OpenSCEANRIO files and make them available to the simulation at runtime.


Additional features

Dissolve references

Resolve paramaters and catalog entries with a few clicks.


Easily export your scenario as an XML file.

Checker Rules Framework

Add your own validator rules for different validation applications.
