function rdf_get_mapping in Drupal 10

Same name and namespace in other branches

1. 8 core/modules/rdf/rdf.module \rdf_get_mapping()
2. 9 core/modules/rdf/rdf.module \rdf_get_mapping()

Returns the RDF mapping object associated with a bundle.

The function reads the rdf_mapping object from the current configuration, or returns a ready-to-use empty one if no configuration entry exists yet for this bundle. This streamlines the manipulation of mapping objects by always returning a consistent object that reflects the current state of the configuration.

Example usage: -Map the 'article' bundle to 'sioc:Post' and the 'title' field to 'dc:title'.

rdf_get_mapping('node', 'article')
  ->setBundleMapping(array(
  'types' => array(
    'sioc:Post',
  ),
))
  ->setFieldMapping('title', array(
  'properties' => array(
    'dc:title',
  ),
))
  ->save();

Parameters

string $entity_type: The entity type.

string $bundle: The bundle.

Return value

\Drupal\rdf\Entity\RdfMapping The RdfMapping object.
