Abstract
Systems and methods are described to provide consistent cross-reference between electronic documents from distributed storage servers. A first document server may receive a query relating to a first document referencing a second document. The first document is stored on the first document server, and the second document is stored on a second document server. The first document server may obtain data relating to a copy of the second document associated with a revision number. The first document server may then send, to the second document server, an update request including the revision number, and then receive from the second document server, data relating to operations that have been committed to the second document after a time associated with the revision number. The first document server may apply the operations that have been committed to the second document to update the copy of the second document, and respond to the query based on a previously stored copy of the first document and the updated copy of the second document.
