--- title: Book JSON --- A `book.json` file is what tells Modopedia the basic properties of a book such as the title, subtitle, type and many other properties. Without a `book.json`, Modopedia will not be aware of your book existing and therefore be unable to load it. ### Datapack Location The `book.json` for your book should be located in a **datapack** at `data//modopedia/books/.json` where `namespace` is the ID of your mod or namespace of your modpack and `book_id` is the ID of your book, both of these need to follow Minecraft's [ResourceLocation rules](https://minecraft.wiki/w/Resource_location). When referencing your book, for example on a book item, `namespace:book_id` should be used. ## JSON Schema Item models for Modopedia books need to be placed inside the **`item/modopedia_books`** folder in your resource pack to be loaded. | ID | Type | Required | Default | Description | |---------------|------------------|----------|-----------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------| | title | String | ✓ | - | Title of the book, supports translation keys. | | subtitle | String | ✗ | - | Subtitle of the book, supports translation keys. | | type | BookType | ✗ | * | Type of book, this is further explained in [Book Types](./book-types).
