Abstract: Methods for formatting a hierarchical data structure having structural elements (“HDS”) are provided. A branch in a directed acyclic graph is spawned. The graph includes a root node and a plurality of sub-nodes respectively corresponding to master and edited versions of the HDS, respectively. An edited version of the HDS is associated with a secondary instance of the HDS, and a change set corresponding thereto. The change set includes user edits. In the method first and second change sets are obtained and, responsive to a user selection, portions thereof are merged to produce a third change set. An additional secondary instance of the HDS is generated by applying the third change set to structural elements included in the master instance of the HDS. The additional secondary instance of the HDS is associated with an edited version of the HDS which, in turn, is associated with a sub-node in the graph.

Abstract: Systems and methods for collaborative document review are disclosed. At least a portion of a hierarchical data structure is displayed. A first plurality of users has an edit privilege to edit the hierarchical data structure. A user selection of a region in the portion of the hierarchical data structure is obtained. In response to the user selection of the region, there is displayed, for each respective user in the first plurality of users, one or more edits associated with the respective user in a corresponding independent panel in a plurality of panels. This plurality of panels is displayed independently of the hierarchical data structure. In some instances, each user in a second plurality of users has review privileges to comment on the hierarchical data structure. One or more comments associated with a user in the second plurality of users is displayed in a same or different panel in the plurality of panels. A comment in the one or more comments is distinct from the one or more edits.
