## Models

### EntryModel

Entry Model

An Entry Model is master data that defines what can be recorded in the Dictionary within GS2-Dictionary.
Each Entry Model represents a type of entity recorded in the Dictionary, such as monsters, items, or avatar parts.

The possession state of an entry is managed as a binary state—recorded or not recorded—and there is no concept of quantity or stacking for a single Entry Model.
