Definitions data source

The definitions data source provides a tree of registries, definition providers and definition properties.

The definitions data source is part of the Magnolia 6 UI framework. There is no fully qualified class name for it.

If you work with the Magnolia 5 UI framework, see Content connector instead.

Example definition

  name: definitions

The data source for the Definitions app takes only an optional name property.

Data source components

Module component mappings can be defined in the context of the current data source (a component section should have an id in the form of <id>datasource-<ds-name></id>, where <ds-name> is configured in the definition).
