Abstract
The disclosed technology generates unique identifiers for content items in a multi-user network-based content management system. The generated identifiers satisfy at least the properties of, (1) the GUID is unique on the local client device; (2) the GUID is preserved across reboots, moves, renames, and content item modifications; (3) the GUID is not preserved when the content item is copied; and (4) the GUID is not reused after a content item is deleted. The unique identifiers allow the content management system to model each user account as a collection of content item objects and globally unique identifiers instead of as a directory-based hierarchy of content items.
