## Content Rating Mapper
You can use the `content_rating_mapper` operation to map content ratings in your library.
Each attribute under `content_rating_mapper` is a separate mapping and has two parts.
* The key (`PG`, `PG-13` in the example below) is what content ratings you want mapped to the value.
* The value (`Y-10` in the example below) is what the content ratings will end up as.
So this example will change go through every item in your library and change the content rating `PG` or `PG-13` to `Y-10` and `R` to `Y-17`.
This example will change go through every item in your library and change the content rating `PG` or `PG-13` to `Y-10` and remove every instance of the content rating `R`.
Creates/Maintains a Plex Meta Manager [Metadata File](../metadata/metadata) with a full `metadata` mapping based on the library's items locked attributes.
If you point to an existing Metadata File then PMM will Sync the changes to the file, so you won't lose non plex changes in the file.
There are a few different options to determine how the `metadata_backup` works.
| `path` | Path to where the metadata will be saved/maintained<br>**Default:** <<library_name>>_Metadata_Backup.yml in your config folder<br>**Values:** Path to Metadata File |
| `exclude` | Exclude all listed attributes from being saved in the metadata file<br>**Values:** Comma-separated string or list of attributes |
| `sync_tags` | All Tag Attributes will have the `.sync` option and blank attribute will be added to sync to as well<br>**Default:** `false`<br>**Values:** `true` or `false` |
| `add_blank_entries` | Will add a line for entries that have no metadata changes<br>**Default:** `true`<br>**Values:** `true` or `false` |
