# UK Content Rating Default Metadata File The `- pmm: content_rating_uk` Metadata File is used to dynamically create collections based on the content ratings available in your library. If you do not use the UK-based rating system within Plex, this file will attempt to match the standard ratings (such as PG-13) to the respective UK rating system (such as 12) Example Collections Created: ![](../images/content_rating_uk.png) The below YAML in your config.yml will create the collections: ```yaml libraries: Movies: metadata_path: - pmm: content_rating_uk ``` ## Template Variables Template Variables can be used to manipulate the file from the default settings which are provided. Note that the `templates_variables:` section only needs to be used if you do NOT want to use the default settings. All [Shared Variables](../variables) are available as well as the additional Variables below which can be used to customize the file. | Variable | Description & Values | |:-----------------|:----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `sort_by` | **Description:** Controls the sort method for the collections
