# Model State

This is a description of the model state for each widget in the core Jupyter
widgets library. The model ID of a widget is the id of the comm object the
widget is using. A reference to a widget is serialized to JSON as a string of
the form `"IPY_MODEL_<MODEL_ID>"`, where `<MODEL_ID>` is the model ID of a
previously created widget of the specified type.

This model specification is for ipywidgets 8.

## Model attributes

Each widget in the Jupyter core widgets is represented below. The heading
represents the model name, module, and version, view name, module, and version
that the widget is registered with.
