Abstract: A method for maintaining revisions for a plurality of documents is described. Pending requests are stored in a workspace revision queue that is shared by the plurality of documents. The pending requests indicate revisions to be carried out on the plurality of documents. A pending request graph is generated for at least some pending requests from the workspace revision queue using a dependency graph for the plurality of documents. The dependency graph represents interdependencies of content references among the plurality of documents. The revisions indicated by the pending requests of the pending request graph are caused to be performed on the plurality of documents according to a dependency ordering based on the pending request graph. The dependency ordering is different from an ordering for the workspace revision queue.
