# Metadata Files Metadata files are used to create and maintain collections and metadata within the Plex libraries on the server. If utilized to their fullest, these files can be used to maintain the entire server's collections and metadata, and can be used as a backup for these in the event of a restore requirement. Collections, templates, metadata, and dynamic collections are defined within one or more Metadata files, which are linked to libraries in the [Libraries Attribute](../config/libraries.md#metadata-path) within the [Configuration File](../config/configuration.md). These are the attributes which can be used within the Metadata File: | Attribute | Description | |:--------------------------------------------------------|:----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | [`templates`](templates) | contains definitions of templates that can be leveraged by multiple collections | | [`external_templates`](templates.md#external-templates) | contains [path types](../config/paths) that point to external templates that can be leveraged by multiple collections | | [`collections`](#collection-attributes) | contains definitions of collections you wish to add to one or more libraries | | [`dynamic_collections`](#dynamic-collection-attributes) | contains definitions of [dynamic collections](dynamic) you wish to create | | [`metadata`](#metadata-attributes) | contains definitions of metadata changes to [movie](metadata/movie), [show](metadata/show), or [music](metadata/music) library's items [movie titles, episode descriptions, etc.] | * One of `metadata`, `collections` or `dynamic_collections` must be present for the Metadata File to execute. * Example Metadata Files can be found in the [Plex Meta Manager Configs Repository](https://github.com/meisnate12/Plex-Meta-Manager-Configs/tree/master/PMM) ## Collection Attributes Plex Meta Manager can run a number of different operations within `collections` and such as: * Automatically build and update collections and playlists * Sync the collection with the source list if one is used * Send missing media to Sonarr/Radarr (Lidarr not supported at this time) * Show and Hide collections at set intervals (i.e. show Christmas collections in December only) Each collection requires its own section within the `collections` attribute and unlike playlists, collections can be built using as many Builders as needed. ```yaml collections: Trending Movies: # ... builders, details, and filters for this collection Popular Movies: # ... builders, details, and filters for this collection etc: # ... builders, details, and filters for this collection ``` There are multiple types of attributes that can be utilized within a collection: * [Builders](builders) * [Settings/Updates](update) * [Filters](filters) ### Example ```yaml collections: Trending: trakt_trending: 10 tmdb_trending_daily: 10 tmdb_trending_weekly: 10 sort_title: +1_Trending sync_mode: sync smart_label: random summary: Movies Trending across the internet Popular: tmdb_popular: 40 imdb_list: url: https://www.imdb.com/search/title/?title_type=feature,tv_movie,documentary,short limit: 40 sort_title: +2_Popular sync_mode: sync smart_label: random summary: Popular Movies across the internet ``` ## Dynamic Collection Attributes Plex Meta Manager can dynamically create collections based on a verity of different criteria, such as * Collections for the top `X` popular people on TMDb (Bruce Willis, Tom Hanks etc.) * Collections for each decade represented in the library (Best of 1990s, Best of 2000s etc.) * Collections for each of the moods/styles within a Music library (A Cappella, Pop Rock etc.) * Collections for each of a Trakt Users Lists. Below is an example dynamic collection which will create a collection for each of the decades represented within the library: ```yaml dynamic_collections: Decades: type: decade ``` ## Metadata Attributes Plex Meta Manager can automatically update items in Plex [Movie](metadata/movie), [Show](metadata/show), and [Music](metadata/music) Libraries based on what's defined within the `metadata` attribute. Each metadata requires its own section within the `metadata` attribute. Each item is defined by the mapping name which must be the same as the item name in the library unless an `alt_title` is specified. ```yaml metadata: Godzilla vs. Mechagodzilla II: # ... details to change for this item Godzilla vs. Megaguirus: # ... details to change for this item Godzilla vs. Megalon: # ... details to change for this item Halloween (Rob Zombie): # ... details to change for this item etc: # ... details to change for this item ``` ### Title, Year, & Edition YAML files cannot have two items with the same mapping name so if you have two movies with the same name you define each one with a name of your choosing. Then use the `title` attribute to specify the real title and the `year` and/or `edition_filter` attribute to specify which of the multiple movies is for this mapping. ```yaml metadata: Godzilla1: title: Godzilla year: 1954 content_rating: R Godzilla2: title: Godzilla year: 1998 content_rating: PG-13 Godzilla3: title: Godzilla year: 1954 edition_filter: Extended content_rating: R ``` **Note: `edition_filter` only works with Movies** ### Alt Title To define an alternative title that the item may be called when searching use `alt_title`. When a title is found matching `alt_title` then the name of the item will be changed to match the mapping name or `title` if specified. For Example, the 2007 movie Halloween shares a name with another movie in the Halloween franchise so this changes the title to `Halloween (Rob Zombie)` if the title is currently Halloween. ```yaml metadata: Halloween (Rob Zombie): alt_title: Halloween year: 2007 ``` ### Example ```yaml metadata: Godzilla1: title: Godzilla year: 1954 content_rating: R Godzilla2: title: Godzilla year: 1998 content_rating: PG-13 Godzilla vs. Mechagodzilla II: content_rating: PG Godzilla vs. Megaguirus: content_rating: PG originally_available: 2000-08-31 Godzilla vs. Megalon: content_rating: G originally_available: 1973-03-17 Halloween (Rob Zombie): alt_title: Halloween year: 2007 ```
