OpenSCENARIO API

Abstract

  • Extensive library for reading, writing and checking scenarios.
  • Fully compliant to OpenSCENARIO 1.3
  • 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.
