UID Element
The UID element is a unique identifier. UID specifies the data record of any of its parent elements within one project.
<UID>
String(16): for Project
Integer: for all other parent elements
</UID>
Parent Elements

Occurrences
Minimum: 1 Maximum: 1 |
Remarks
The UID element is a string only for the Project element. The UID child element in Project is deprecated in Microsoft Office Project 2007.
For its other parent elements, UID is an integer. UID values are unique only within a project, not across multiple projects.
For a task, each UID is used only once within the project. If you create a task named T3 with UID = 3 and ID = 3, delete the task, and then create a new task named T3 with ID = 3, the new task UID is 4.
