Library Operations
There are a variety of Library Operations that can be utilized in a library.
Within each library, operations can be defined by using the operations attribute, as demonstrated below.
When not using a list under operations the whole operations value is one block.
???+ example
```yaml
libraries:
Movies:
collection_files:
- pmm: imdb
operations:
mass_critic_rating_update: tmdb
split_duplicates: true
```
Operation Blocks
You can create individual blocks of operations by using a list under operations with each item in the list being a
"block" that can be individually scheduled.
???+ example
```yaml
libraries:
Movies:
collection_files:
- pmm: imdb
operations:
- schedule: weekly(friday)
mass_critic_rating_update: tmdb
- schedule: weekly(saturday)
split_duplicates: true
```

This does not affect the icons displayed in the Plex UI. This will place the number of your choice in the

Tomatoes. The human who decided to put TMDb ratings in the critic slot and Letterboxd ratings in the audience
slot is the only party who knows that the ratings are no longer Rotten Tomatoes. One primary use of this feature
is to put ratings overlays on posters. More information on what PMM can do with these ratings can be found
