# US Content Rating Default Metadata File
The `- pmm: content_rating_us` Metadata File is used to dynamically create collections based on the content ratings available in your library.
If you do not use the US-based rating system within Plex, this file will attempt to match the international ratings (such as "gb/12A") to the respective US rating system (such as "PG-13")
Example Collections Created:
![](../images/moviecontent_rating_us.png)
The below YAML in your config.yml will create the collections:
```yaml
libraries:
Movies:
metadata_path:
- pmm: content_rating_us
```
ohhh
## 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.
Below are the available variables which can be used to customize the file.
| Variable | Usage | Default Value | Values |
|:-------------------|:-----------------------------------------------------------------------------------------------------|----------------|:--------------------------------------------------------------------------------------------------------------------------------------------------------------:|
| sort_by | Controls the sort method for the collections | `release.desc` | Any sort method in the [Sorts Options Table](#sort-options) |
| collection_section | Controls the sort order of these collections against other default collections | `14` | Any number |
| collection_mode | Controls the collection mode of these collections | `default` | `default` - Library default
`hide` - Hide Collection
`hide_items`- Hide Items in this Collection
`show_items` - Show this Collection and its Items |
| use_other | Controls whether an "Other" collection is created for any items not included in the initial criteria | `true` | `true` or `false` |
| use_separator | Controls whether a separator is created | `true` | `true` or `false` |
| sep_style | Sets the theme of the separator | `orig` | `orig`, `blue`, `gray`, `green`, `purple`, `red`, `stb` |
| item_radarr_tag | rADARR Tag for existing items | | list of tag(s) to be applied to existing items |
The below shows an example config.yml with all the template_variables set away from their defaults:
```yaml
libraries:
Movies:
metadata_path:
- pmm: content_rating_us
template_variables:
sort_by: title.asc
collection_section: 25
collection_mode: show_items
use_other: false
use_separator: false
sep_style: blue
```
Dynamic Collections attributes can also be edited to tweak the setup of the collections. The YAML file which creates the `content_rating_us` collections can be found [here](https://github.com/meisnate12/Plex-Meta-Manager/blob/defaults/defaults/content_rating_us.yml)
An example of this is; to map the "de/18" content rating to "R", the following template variable can be used:
```yaml
libraries:
Movies:
metadata_path:
- pmm: content_rating_us
template_variables:
addons:
R:
- "de/18"
```
