# created\_by\_app and created\_by\_user fields on Metaobject and MetaobjectDefinition types

We are introducing two new fields in the `MetaobjectDefinition` type:

* `createdByApp`: The app used to create the metaobject definition.
* `createdByStaff`: The staff member who created the metaobject definition.

Similarly, we are introducing two new fields in the `Metaobject` type:

* `createdByApp`: The app used to create the object.
* `createdByStaff`: The staff member who created the metaobject.

Additionally, we are deprecating the `staffMember` field in the `Metaobject` type. This field is being deprecated, and the `createdByStaff` field should be used instead.
