Create a custom taxonomy

You can register a taxonomy with register_taxonomy, or declare it in a YAML file of a config/ directory. Simply registers it on the init action.

config/taxonomy/project-tag.yaml

taxonomy:
  project_tag:
    object_type: project
    args:
      label: Technologies
      labels:
        name: Technologies
        singular_name: Technology

• object_type (required): the post type, or a list of post types.
• args: the arguments of register_taxonomy, without restriction.

Translations

trans(text, domain) is replaced by __(), but only for the values directly under args (like label), not inside args.labels:

taxonomy:
  project_tag:
    object_type: project
    args:
      label: trans(Technologies, mydomain)

As for post types, spaces are removed from the text, and the translation is cached in the language active when the container is compiled.

To give the taxonomy a model, see create a model.
