Abstract
Notebook applications may be employed to create, edit, and/or share collaborative documents. In a classroom setting, a notebook application may enable interactivity among a teacher and students. A page lock may be provided for the notebook application to prevent students from making unauthorized changes, such as editing a page after an assignment deadline or erasing teacher feedback, while still enabling the teacher read and write capabilities. For example, a notebook page may be rendered with read and write permissions for the teacher and student(s). The teacher may be provided an option to set a lock on the page to disable one or more of the students' write permissions. The teacher may select a first timing parameter associated with setting the lock, which defines a future date and time or event to trigger the disabling of the students' write permissions. The lock may be set based on the first timing parameter.
