Abstract: A computer that is programmed with collaboration software receives a new value of an attribute (or property or characteristic) which is specific to a label (or tag or category) as applied to an object managed by the computer. The computer does not use the new value to overwrite a corresponding old value in existing metadata. Instead, the computer is programmed to hold the new value in an incremental label application for the object. The computer is further programmed to respond to a request for the object's label application, by retrieving the incremental label application, and a full application of said label to said object. The computer uses attribute values in the incremental label application to update corresponding attribute values in a copy of the full label application, in a time sequence based on the time of creation of incremental label applications, thereby to generate a current label application.

Abstract: Architecture for multi-level undo on a client in grid-based applications. The architecture is a control driven cascading changes system where change tracking works seamlessly in asynchronous (and synchronous) scenarios. A client application is associated with a grid object and, instantiates and configures the grid object. The application can initiate a change to data in the grid and/or the user can edit the data in the grid directly. A result of the change is a notification to the application, the notification including an order key. The application consumes the notification and can then append new changes based on synchronous or asynchronous computations by calling an update function using the order key. The application uses the key to attach further updates which are properly collected together for undo/redo.

The resized data chunks are transmitted from the source storage system to the target storage system for replication.

Abstract: A synchronization system is described herein that synchronizes two environments by correctly matching identity objects in a source environment with related objects in a target environment. In addition to matching identities based on primitive attributes, the system matches identities across multiple heterogeneous environments based on their relative positions in an identity graph. The system builds the identity graph by first matching some identity objects based on primitive attribute value comparisons. The system fills in the remainder of the identity graph by comparing references to/from the matched identity objects. The combination of attribute value comparisons and comparing references enables identity-aware applications to complete a single identity graph, determine the equivalency of identities in this graph, and apply policy based on this new relationship.
