OpenSCENARIO API

Abstract

• Extensive library for reading and checking scenarios.
• Fully compliant to OpenSCENARIO 1.2
• Includes an executable checker (See Getting Started).
• Implementation platform is C++

Features

• Reading and processing of XML scenario files.
• Precise warnings and errors on a line and column based file location.
• API for browsing the OpenSCENARIO tree.

More Features

• Resolving $notated parameters
• Resolving catalog references
• Resolving object references
• Checking model constraints from the standard (Range checker rules)

Architectural features and extension points

• Abstracting the model from its implementation Feature: Providing an API to browse the tree--hiding the implementations.
• Abstracting from storage media Extension Point: Reading from zipped files, from databases or from the cloud by writing your own resource locator classes.
• Abstracting from storage formats Extension Point: Write your own loader class to read from binary files or from JSON etc.
• Checker rule API Extension Point: Write your own checker rules. E.g. for your company‘s set of authoring guidelines.
• Architecture is transferable to different platforms E.g. JAVA, Python

Use Cases

Primary Use Cases

• Using the library as a stand alone checker.
• Integrating the library in simulators and editors.
• Analyzing scenarios for labeling issues (e.g. in OpenLabel).

More Use Cases

• Building customer specific sets of authoring guidelines with the generic checker rule interface.
• Enabling reading access to backends and to the cloud.
• Analyzing scenarios for building comparators, doing data mining etc.
• Storing pre-compiled scenarios in efficient storage formats in databases.
