Abstract: 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.

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.

Abstract: 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.

Abstract: 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.

Abstract: A method, system, and apparatus are provided for collaborating on an electronic document. According to the method, a data structure may be maintained at each of the computer systems participating in the collaborative session that represents the contents of a shared document. When user input is received at one of the computer systems modifying the document, the data structure is updated to reflect the modification. In response to the modification, the changes to the data structure are periodically identified and collected as a revision that identifies only the changes made to the data structure as a result of the edits made since the previous revision was taken. The revision is packaged and transmitted to each of the participants in the sharing session. The revisions are merged into the copy of the data structure stored at the participating computer systems.

Abstract: 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.

Abstract: A storage system according to one embodiment for managing a first file includes a blob storage and a handler. The blob storage may be configured to store data related to the first file temporarily. The handler may be configured to store in the blob storage any data related to the first file and received from an application. The handler also may be configured to transfer at least a portion of the data from the blob storage to persistent storage in response to a commit instruction received from an application or generated by the handler. The handler also may be configured to retrieve any portion of the data stored in the blob storage and to send the same to a requesting application in response to an access request.

Abstract: 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.
