Discovery: Modelling Collections on the Backend

[bradenmacdonald]

1. Review the Figma mid-fi frames related to Collections.
2. Create a high-level implementation plan, get it approved, then create a list of stories for this epic and estimate each one. Requirements include:
   • store/model Collections on the backend (in edx-platform, probably in the content_libraries app; or maybe in openedx-learning)
   • store Collections in the Studio Content meilisearch index, alongside Library/Course Blocks
   • Collections have name, tags, description, date created/modified
   • Collection Home Page with same cards, keywords search, sorting, and filtering options as the new Library Home Page
   • Add to Collection workflow needs to modify the "Library Home View" so that it can appear in a modal, each card has a "select" checkbox, and collections are hidden.
   • collection info sidebar (set collection tags, name, description)
   • From a Collection Home Page, user can create new content and it will be added to the collection.

Note that:

• collections can be tagged
• collections cannot be added to collections
• components can be part of multiple collections
• we could use tags to indicate which components are in which collections; e.g. a system "collections" taxonomy that's hidden from users
