xCDL Metadata

note

Work in progress.

The xCDL metadata is a set of definitions used by xcdl to drive the configuration process.

These definitions are stored in the xcdl*.json file located in the project's top-level folder, as well as in additional JSON files located in subfolders.

For projects that build executables, like applications, and sub-projects like tests, the top-level xcdl*.json file must define a cdlProject object with cdlConfigurations.

For projects defining dependencies, like source libraries, the top-level xcdl*.json file can directly define cdlComponents.

Global properties

The xCDL definitions include the following global properties:

• $schema
• license
• copyright
• minimumXcdlRequired

Objects

The xCDL definitions include the following objects, each with its own properties:

• cdlArtefacts
• cdlComponents
• cdlInterfaces
• cdlOptions
• cdlProject
• cdlConfigurations
• cdlTests
