A method for providing a binary data file to at least a first client application and a second client application includes receiving a first request to access the binary data file from the first client application, and identifying a first document model associated with the binary data file, wherein the first document model reflects edits made to the binary data file by the first client application and the second client application. The method further includes transmitting data corresponding to the first document model to the first client application, receiving, from the second client application, a second request indicating a modification to the binary data file, revising the first document model associated with the binary data file to include the modification to the binary data file, and transmitting data corresponding to the revised first document model to the second client application.
