# Decade Default Metadata File

The `- pmm: decade` Metadata File is used to dynamically create collections based on the decades available in your library, sorted by critic rating to create a "best of <decade>"

Example Collections Created:

![](../images/decade.png)

The below YAML in your config.yml will create the collections:
```yaml
libraries:
  Movies:
    metadata_path:
      - pmm: decade
```


## 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                                                                             |

| use_other          | Controls whether an "Other" collection is created for any items not included in the initial criteria | `true`                 |                                                                       `true` or `false`                                                                        |

| sep_style          | Sets the theme of the separator                                                                      | `orig`                 |                                                    `orig`, `blue`, `gray`, `green`, `purple`, `red`, `stb`                                                     |
| item_radarr_tag    | Sonarr 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: decade
        template_variables:
          sort_by: title.asc
          collection_section: 18
          collection_mode: show_items
          use_other: false
          use_separator: false
          sep_style: purple
```

Dynamic Collections attributes can also be edited to tweak the setup of the collections. The YAML file which creates the `decade` collections can be found [here](https://github.com/meisnate12/Plex-Meta-Manager/blob/defaults/defaults/decade.yml)

An example of this is; to change the collection titles to "Best Movies of <decade>, the following template variable can be used:

```yaml
libraries:
  Movies:
    metadata_path:
      - pmm: decade
        template_variables:
          title_format: Best <<library_type>>s of <<key_name>>
```
