# Created by and last edited by properties in Block, Page and Database objects

> over 3 years ago by Alp Artar

We have added `created_by` and `last_edited_by` properties for [block](/reference/block), [page](/reference/page) and [database objects](/reference/database) corresponding to the users who have created or last edited these objects. Both properties are [user objects](/reference/user) which will contain `object` and `id` keys. This is a backwards compatible change that is available in older versions of the API as well.

We have also added a boolean `archived` property for [database objects](/reference/database) to denote if the database has been deleted. You can use the `archived` property to archive or unarchive a database and its descendants when [updating the database](/reference/update-a-database).
