## Title
Saving and restoring collaborative applications in context

## Abstract

A method for saving and restoring collaborative applications to a selected earlier time, may include saving, by a processing device, content for each collaborative application of a plurality of collaborative applications as a user uses each of the collaborative applications. The method may additionally include restoring each collaborative application to a selected earlier time in response to the selected earlier time being selected by the user. The method may further include presenting the content of each collaborative application at the selected earlier time to the user in response to each collaborative application being restored to the selected earlier time, wherein each collaborative application is presented in an original context from the selected earlier time.

## Background
BACKGROUND
Aspects of the present invention relate to restoring collaborative applications to a previous time period, and more particularly to a method, system and computer program product for saving and restoring collaborative applications in context to a selected earlier time.
Computer users today typically have multiple computer tools or applications running simultaneously. Several of these tools or applications may have the capability of collaborating or working cooperatively with one another. For example e-mail, instant messaging, documents, presentations shared spaces, computer application Integration Development Environment (IDE) and other applications may be used in conjunction with one another or collaboratively.
Computer users often communicate with colleagues using more then one application. The content of one application may influence what is described in another application or collaborative application. For example a user may be instant messaging a colleague on a particular topic and may create a note which is based on the information shared in the chat session in another collaborative application. Each of these applications may allow the user to review past information but only separately, i.e., either the chat history or the note. However in a collaborative environment, the entire context may be much more valuable or meaningful than the individual pieces.
BRIEF SUMMARY
According to one aspect of the present invention, a method for saving and restoring collaborative applications to a selected earlier time, may include saving, by a processing device, content for each collaborative application of a plurality of collaborative applications as a user uses each of the collaborative applications. The method may also include restoring, by the processing device, each collaborative application to a selected earlier time in response to the selected earlier time being selected by the user. The method may further include presenting, by the processing device, the content of each collaborative application at the selected earlier time to the user in response to each collaborative application being restored to the selected earlier time. Each collaborative application may be presented in an original context from the selected earlier time.
According to another aspect of the present invention, a system for saving and restoring collaborative applications to a selected earlier time may include a processor. A module operating on the processor may be adapted for saving content of each collaborative application and restoring the content of each collaborative application to a selected earlier time. The module may include a module to save the content for each collaborative application of a plurality of applications as a user uses each of the collaborative applications. The module for saving and restoring content of each collaborative application may also include another module to restore the content of each collaborative application to the selected earlier time in response to the selected earlier time being selected by the user. The module for saving and restoring content of each collaborative application may include an additional module to present the restored content of each collaborative application at the selected earlier time on a display to the user in response to each collaborative application being restored to the selected time. Each collaborative application may be presented in an original context at the selected earlier time.
According to a further aspect of the present invention, a computer program product for saving and restoring collaborative applications to a selected earlier time may include a computer readable storage medium having computer readable program code embodied therewith. The computer readable program code may include computer readable program code configured to save content for each collaborative application of a plurality of collaborative applications as a user uses each of the collaborative applications. The computer readable program code may also include computer readable program code configured to restore each collaborative application to a selected earlier time in response to the selected earlier time being selected by the user. The computer readable program code may additionally include computer readable program code configured to present the content of each collaborative application at the selected earlier time to the user in response to each collaborative application being restored to the selected earlier time. Each collaborative application may be presented in an original context from the selected earlier time.

Computer program code for carrying out operations for aspects of the present invention may be written in any combination of one or more programming languages, including an object oriented programming language such as Java, Smalltalk, C++ or the like and conventional procedural programming languages, such as the “C” programming language or similar programming languages. The program code may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user's computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider).
Aspects of the present invention are described below with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems) and computer program products according to embodiments of the invention. It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer program instructions. These computer program instructions may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks.
These computer program instructions may also be stored in a computer readable medium that can direct a computer, other programmable data processing apparatus, or other devices to function in a particular manner, such that the instructions stored in the computer readable medium produce an article of manufacture including instructions which implement the function/act specified in the flowchart and/or block diagram block or blocks.
The computer program instructions may also be loaded onto a computer, other programmable data processing apparatus, or other devices to cause a series of operational steps to be performed on the computer, other programmable apparatus or other devices to produce a computer implemented process such that the instructions which execute on the computer or other programmable apparatus provide processes for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks.
FIG. 1 is a flowchart of an example of a method 100 for saving and restoring collaborative applications in context to a selected earlier time in accordance with an embodiment of the present invention. A user is able to track, capture or store the state of all tools or applications and when desired to return to a view of all the states or content of the applications or tools at a selected point earlier in time. Tracking, capturing or storing the state or content of applications can typically be easily implemented. If such a feature does not already exist, a background backup facility or module may be incorporated in each application. Such features already exist in many applications. This may be the case in applications from the same vendor, and particularly if the applications are collaborative applications and may be used in conjunction or cooperatively with one another similar to that previously described. An application programming interface (API) may call the application with a time/date parameter and have the application display its state or content at the selected earlier point in time. As described herein a mechanism or GUI may permit the user to interact with the application. A standardized API available across all applications could be used to implement the features described herein.
In block 102, a graphical user interface (GUI) may be presented for selecting parameters for saving and restoring applications. The GUI may be presented in response to a user selecting an icon, menu item of the like to activate the saving and restoring of application feature. The applications being saved for possible future restoration as described herein may be collaborative applications. Collaborative applications may be defined as applications or computer tools that may compliment one another or that may be used in conjunction with one another. Examples may include but are not limited to email, instant messaging (IM), notes that may be taken in another application related to emails and/or IM dialogues, documents, presentations, computer application Integration Development Environment (IDE), and similar applications or tools. Collaborative applications may be used by multiple users and as such may define a collaborative environment. Collaborative may be defined in one context as a recursive process where two or more people or organizations may work together in an intersection of common goals. Such collaboration may result in a final goal of something produced by a computer application, such as a note, presentation, computer application, etc.
Referring also to FIG. 2, FIG. 2 is an example of a GUI 200 for selecting settings or parameters for saving and restoring collaborative applications to a selected earlier time in accordance with an embodiment of the present invention. The GUI 200 may include a feature 202, such as a menu, dropdown list or similar feature for selecting or choosing applications that may be tracked or recorded and saved for restoration in the future to a selected earlier time as described herein.
The GUI 200 may also include a feature 204 for selecting a time interval between different saving or capturing procedures or occurrences. The state or content of the application may be continuously tracked, recorded and saved or the state or content may be saved at selected time intervals to save processing overhead and file storage capacity, if appropriate or needed under the circumstances.
The GUI 200 may additionally include a feature 206 for selecting or choosing a retention duration or time period or number of days a saved state or content of an application is stored. The retention duration may be set to overwrite the earliest saved state when the allotted memory space or storage facility becomes full.
The GUI 200 may further include a feature 208 for selecting the granularity or amount of detail of the state or content of the applications to be recorded or captured and saved. All details of the state of the application may be saved or only selected features, such as for example only text.
The GUI 200 may also include other features, such as feature 210 for selecting other parameters related to saving the state or content of the application, and feature 212 for selecting parameters related to restoring the state or content of each of the applications at a selected earlier time.
Returning to FIG. 1, in block 104, the content or state of each chosen application or collaborative application may be recorded or tracked and stored as the user uses the collaborative applications in their normal way. The content or state of each application may be recorded, tracked and stored based on selected parameters as previously described. The state or content of each collaborative application may be stored on the user's computer memory, on an on-line database, on a server or other storage device or facility that may be associated with the user's computer system or may be online and accessible over a network as described herein.
A continuous, cross application state with collaboration text of each collaborative application may be saved. For example, a user may be viewing a document in a word processing application with a team of others and using a chat session to keep notes. A record of the time when comments are entered into the chat and the state of the word processing document may be recorded or saved, i.e., the page that is being viewed, the snapshot of the content, the state of comments or highlights added to the document, etc. may be saved or recorded. This set of recorded snapshots of collaboration context may be stored in such a way that the user may view what occurred in the context of the collaboration when restored to this earlier time at a later time. To answer a question such as, why was paragraph 2 added to page 5 of the document, the user can scroll back using a mechanism, such as a slide bar on a timeline as described herein, or other mechanism to scroll back through the collaboration context recording. When the user reaches the section that shows page 5 of the document being edited, the user can also view the contents of the chat session at that selected point in time. That chat may potentially help the user to understand why the paragraph was added.
In block 106, a GUI may be presented for restoring the applications in response to the user selecting a restore feature. The restore feature may be an icon, menu item or other mechanism for activating the restore function.
In block 108, a mechanism may be presented to the user for restoring each application to a selected earlier time. The mechanism may permit selection over a continuum of time over which each of the chosen collaborative applications has been saved. For example, the mechanism may be a timeline or similar arrangement. The timeline may be presented along with a moveable or slidable restore bar that may be slid along the timeline for selecting an earlier time to which the collaborative applications may be restored. Each collaborative application may be restored to the selected earlier time selected by the user to thereby result in the collaborative environment's context at that selected earlier time. Examples of a timeline and slidable restore bar will be described in more detail with reference to FIGS. 3A and 3B, and FIG. 4.
In block 110, each application restored to a selected earlier time may be presented to the user. Each application may be restored to the state or content of the application at the selected earlier time corresponding to the time of the position of the slidable restore bar on the timeline selected by the user. The user may also operate a button or other feature that may be labeled “Restore” or similar label identifying the features function in order for the method 100 or system to restore the applications to the selected earlier time and to present the content or state of each application to the user on a computer display or other output device.
The chosen collaborative applications may be simultaneously invoked and brought back to the save state at the time corresponding to the selected earlier time position of the restore bar on the timeline.
The restored applications may be at a reduced size or minimized condition in order to permit a representation of all restored chosen applications on the display or other device. As described in more detail herein, the restore bar or other feature may include a mechanism to permit selection of an application for the selected application to be maximized or expanded in size for viewing. The restore bar feature or other feature may be clicked-on or otherwise operated to minimize the selected application to permit another application to be maximized or the maximized application may be automatically minimized in response to another restored application being maximized. As described in more detail herein, the restore bar may also include a feature or an indication of the number of applications that may be restorable and/or that have been restored to the selected earlier time.
In another embodiment, selection tabs may be provided for selecting a particular application or applications for viewing when all restored applications are not able to be effectively presented on the display or other device.
FIGS. 3A and 3B are each an example of a GUI 300 illustrating restoring collaborative applications to a selected earlier time in accordance with an embodiment of the present invention. The GUI 300 may include a timeline 302 and a slidable restore bar 304. The restore bar 304 is slidable along the timeline 302 using a computer pointing device or similar device for positioning the restore bar 304 at a selected earlier time for restoring the applications to their state including content at the earlier time. The collaborative applications 306 and 308 may then be restored and presented in the GUI 300. The GUI 300 may include a restore button 310 or other feature that may be operated after the restore bar 302 is positioned to the selected earlier time to which the applications 306 and 308 are to be restored. In another embodiment, the restore bar 304 may be clicked-on or operated to start the process of restoring the applications 306 and 308 to the selected earlier time on the timeline 302. Accordingly, the applications 306 and 308 may be restored to the same selected earlier time and presented in context to the user including their respective states and content as they appeared at the earlier time.
The GUI 300 may also include an indication of the number of applications that may be stored or have been restored or both. In one embodiment, the indication of the number of applications may include a size of the slidable restore bar 304. For example, the restore bar 304 may have a width sized to correspond to the number of collaborative applications 306 and 308. As illustrated in FIG. 3A, the restore bar 304 has a predetermined width corresponding to the two restored applications 306 and 308 and the restore bar 304a in FIG. 3B has another predetermined narrower width corresponding to the one restored application 312. If there were more than two restorable or restored applications, the restore bar 304 may been wider than that illustrated in FIG. 3A.
FIG. 4 is an example of a GUI 400 illustrating restoring selected collaborative applications to a selected earlier time in accordance with another embodiment of the present invention. The GUI 400 may include a timeline 402 similar to the timeline 302 in FIGS. 3A and 3B. The GUI 400 may also include a slidable restore bar 404 that is slidable along the timeline 402 to select an earlier time to which the collaborative applications 406 and 408 may be restored. The slidable restore bar 404 may be divided into a number of segments corresponding to the number of applications 406 and 408 that may be restored to the selected earlier time or that may have been restored to the selected earlier time or both. Each segment of the restore bar 404 may include a feature to identify the particular application 406 or 408 to which the segment corresponds. For example, each segment may be a different color to identify the particular application to which the segment corresponds. The particular application 406 or 408 may be alternately maximize or minimized for viewing in response to the segment corresponding to the particular application 406 or 408 being clicked-on or otherwise operated.
The GUI 400 may also include a button 410 that may be labeled “Restore” or the like. The “Restore” button 410 may be operated by the user after the restore bar 404 has been positioned to the desired or selected time to which the applications 406 and 408 are to be restored to start the process for restoring the applications 406 and 408 to the selected earlier time.
FIG. 5 is a block schematic diagram of an example of a system 500 for saving and restoring collaborative applications in context to a selected earlier time in accordance with an embodiment of the present invention. The method 100 of FIG. 1 may be embodied in or performed by the system 500. The GUIs illustrated in FIGS. 2, 3A, 3B and 4 may be generated and presented by the system 500. The system 500 may include a processing device 502. The processing device 502 may be a server or similar processing device. A module 504 for saving and restoring applications, that may be collaborative applications, to a selected earlier time may be stored on the processing device 502 and may be operable on the processing device 502 for saving and restoring collaborative applications or other applications or tools similar to that described herein. The module 504 may be stored on a file system of the processing device 502. Portions of or all of the method 100 may be embodied in or performed by the module 504.
The state or content of the collaborative applications similar that previously described may be recorded and saved in a storage device 506 on the processing device 502 or server. In another embodiment, the recorded applications 506 may be stored in a database 508 accessible online or via a network 510.
A user 512 of the saving and restoring applications feature may use a computer system 514 to access the processing device 502 or server and module 504 for saving and restoring applications. The computer system 514 may include a processor 516 to control operation of the computer system 514 and a file system 518, memory or similar data storage device. An operating system 520, applications 522 and other programs may be stored on the file system 518 for running or operating on the processor 516. A web or Internet browser 523 may also be stored on the file system 518 for accessing the processing device 502 or server via the network 510 for saving and restoring applications or tools as described herein. The network 510 may be the Internet, an intranet or other private or proprietary network.
The computer system 514 may also include a display 524, a speaker system 526, and one or more input devices, output devices or combination input/output devices, collectively I/O devices 528. The I/O devices 528 may include a keyboard, pointing device, such as a mouse, disk drives and any other devices to permit a user, such as user 512, to interface with and control operation of the computer system 514 and to access the module 504 or system for saving and restoring applications. The display 524 may present the GUIs, such as the exemplary GUIs illustrated in FIGS. 2, 3A, 3B and 4 and other information related to the features described herein. The I/O device 528 may also present GUIs and other information.
In accordance with an embodiment, a module 530 for saving and restoring applications may be stored on the file system 518 of the computer system 514 and operable on the processor 516 to perform the operations described herein. The module 530 may be in lieu of the module 504 on the processing device 502 or the module 530 may perform some of the features and operations described herein and the module 504 may perform other features and operations described herein.
This saving and restoring features described herein are different from backup applications such as APPLE® TIMEMACHINE® in that the present invention is capable of tracking the state or content of multiple applications at the same time and then restoring their states simultaneously to save processing overhead and file storage capacity. Additionally, the present invention provides restoring multiple chosen collaborative applications to the selected earlier time as selected by the user, thereby resulting in the collaborative applications or collaborative environment's context at the earlier time being presentable. The view of the synchronization of the original context between the applications or collaborative applications is thus restored to the selected earlier time. In contrast, backup/recovery applications only serve to view a single application's state at a point in time. The present invention provides a significant difference in a collaborative environment, as each application provides content or context to the environment or conversation. APPLE® and APPLE TIMEMACHINE® are trademarks of Apple Computer, Inc. in the United States, other countries or both.
