# Class ExtensibleObject

- [TopLevel.Object](/docs/commerce/b2c-commerce/references/b2c-script-api/TopLevel.Object.md)
  - [dw.object.PersistentObject](/docs/commerce/b2c-commerce/references/b2c-script-api/dw.object.PersistentObject.md)
    - [dw.object.ExtensibleObject](/docs/commerce/b2c-commerce/references/b2c-script-api/dw.object.ExtensibleObject.md)

Base class for all persistent business objects in Commerce Cloud Digital that
are customizable through the metadata system. All objects in Digital
that have custom attributes derive from ExtensibleObject including
both system-defined and custom objects. The describe() method provides access
to the related object-type metadata. The method getCustom() is the central
point to retrieve and store the objects attribute values themselves.
