A collaborative authoring application provides an authoring environment in which two or more users can edit a document concurrently. Each user edits a copy of the document, sends updates to a master copy of the document, and receives updates from the master copy of the document. The authoring environment generally inhibits the users from providing conflicting editing instructions to the master copy of the document. For example, each user can generate a content lock about one or more data units within the document. The authoring environment may synchronize content locks automatically and content only at the request of the user.

Collaborative authoring

Concepts and technologies are described herein for cache management. In accordance with the concepts and technologies disclosed herein, the server computer can be configured to communicate with a client device configured to execute a cache module to maintain a cache storing data downloaded from and/or uploaded to the server computer by the client device. The server computer can be configured to receive requests for data stored at the server computer. The server computer can be configured to respond to the request with hashes that correspond to the requested data. The client device can search the cache for the hashes, obtain the data from the cache if the hashes are found, and/or download the data from the server computer if the hashes are not found. The client device also can be configured to update the cache upon uploading the data to the server computer.

Cache management

The concepts relate to data handling, and more specifically to data handling scenarios where data is revised on one computer and stored on another computer. One example can obtain a set of blobs relating to revisions of a file. The example can determine a target size of datastore blobs. In an instance where a total size of the set of blobs is less than the target size, this example can aggregate the set of blobs into an individual datastore blob. Otherwise, the example can identify new or edited individual blobs of the set and aggregate the new or edited individual blobs into first datastore blobs. The example can also aggregate other individual blobs of the set into second datastore blobs.

Data handling

Embodiments described herein may involve enabling applications to cooperate with a system-level sync framework. The sync framework may provide system synchronization of files between user devices and a cloud storage service. Arbitrary applications on a user computing device can communicate with the sync framework to temporarily suspend synchronization of a specified file by the sync framework. The application can register functions with the sync framework that the sync framework can invoke in relation to suspending synchronization, continuing to provide system-level access to the file for arbitrary applications, and resuming synchronization.

Sync framework extensibility

Example systems, methods, and data structures are directed at synchronizing documents. One example data structure includes receiving a request from a first client to edit a document, and sending short-term check out metadata to the first client to begin an editing session. The data structure includes a plurality of cells and a plurality of data objects defining content of the document. Each data object is associated with one of the cells and has an object identifier that uniquely identifies the data object within the associated cell, and is configured to communicate with other cells and with objects within the associated cell. In addition, each of the cells is defined so that each other cell remains unaffected by changes to data objects of the cell.

Document synchronization over stateless protocols

The present invention relates to new and improved embodiments of systems and methods for using a 'pen' input as a temporary pointer to highlight a portion of a document and having the 'ink' disappear. In embodiments, a method and system for temporarily marking a portion of a document comprises sending a marking directive that produces a visual indicia on a document being viewed on two or more display devices connected over a network, waiting a period of time, and automatically erasing the visual indicia on the document being viewed on the two or more display devices.

Method and system for creating temporary visual indicia

Example systems and methods are directed at maintaining and retrieving presence metadata. One example method includes receiving a request from a first client to edit a document file, and sending short-term check out metadata to the first client to begin an editing session. The method also includes writing the transition ID to a transition table stored in a cache, wherein the presence of another transition ID in the cache indicates that a document has switched from a single-client mode to a multi-client mode. An example system includes a processing unit operative to receive a document, the document including short-term check out metadata indicating an editing session has begun, ping a cache to determine if another transition ID is stored in the cache, and send a transition ID to a transition table stored in a cache to switch from a single-client mode to a multi-client mode.

Caching infrastructure

As changes are made to a document, each change may be assigned an extended identifier comprising a globally unique identifier (GUID) component and an integer component. Upon determining that the same GUID component is used in identifiers for multiple changes, the GUID component may be mapped to a range of indices. Each index of the range of indices may then be used to represent the same GUID component in each extended identifier.

Identifier compression for file synchronization via soap over HTTP

Embodiments are provided for synchronizing file partitions utilizing a server storage model in a client-server computer network. Edits to content of an electronic document may be received at a client computer. The content may be included in a first partition of a file stored on a server computer. The first partition may include a first stream which includes the electronic document content. The file may include multiple partitions with each partition including one or more streams. The client computer may generate metadata in a second partition of the file. The metadata may be associated with the edits to the electronic document content in the first partition. The second partition may then be individually synchronized with the server computer to store the metadata. The first partition may then be individually synchronized with the server computer to store the edits made to the electronic document content.

Synchronizing file partitions utilizing a server storage model

Examples are related to systems and methods for controlling access to document files on a document server. One example system includes document files stored on a document server, at least one of the document files referencing a file lock, and a document access processing module. The example document access processing module includes a file sharing processing module that determines a coauthoring status of a software application of a client computer requesting access to the document file, and a file lock processing module that stores one or more file locks and that controls the setting and resetting of file locks. The example document access processing module uses the coauthoring status of the software application and the file lock status of a document file to determine whether a software application is permitted to have write access to the document file.
