Abstract: Systems and methods for presenting collaboration activity to a particular user are disclosed. A method embodiment commences by recording event records that codify one or more event attributes corresponding to one or more content object access events. The content object access events are associated with two or more users that interact with the content objects. At a later moment in time, a subset of event records is selected, the selection being based at least in part on timestamps of the content object access events. A display order to apply to the selected subset of event records is determined, the order being based at least in part on timestamps of collaboration events arising from the users. Event messages to present in a user interface are generated, and the event messages are then displayed in the user interface in accordance with the display order.

Abstract: A multi-user collaboration system. User-specific change markings are applied to a collaboration object. The user-specific changes to be presented are time-oriented, based on a time of a last view of the collaboration object. A plurality of users that have access to the collaboration object are identified. Time-ordered versions of the collaboration object are captured. Each captured version corresponds to changes made to the collaboration object by any of the users. When a request to view the collaboration object is received from a subject user, a method determines the latest version of the collaboration object and also determines the specific last accessed version of the collaboration object that was seen by the subject user. The two versions are compared, and the comparison changes are used to generate user-specific change markings. The collaboration object with the generated user-specific change markings is presented by rendering the user-specific change markings on respective user-specific devices.
