Description

The method of cooperative system, collaboration server, transmission document files

The present invention relates to a system, this system couples together a plurality of users by a communication network, cooperative system especially, and this machine file and the collaborative work in the Any user shared by this system.

Recently, in order to build a new system that sends and share the category information of the information that can not handle such as Qualitative Knowledge and technical know-how in system, the introducing work of having carried out computing machine rapidly is to support exchange message between a plurality of users (after this being called cooperation).When the system that supports above-mentioned cooperation realizes by building an in-house network, can will be added to product information such as image and figure and get on the master data of the customer data of textual form storage and result and so on, therefore might be master data as the information sharing that use value is more arranged.By it being extended to extranets, can make product be convenient to cooperate with relevant company and make each process more reasonable by sharing information with dealer and supplier with research and development or engineering management.And, if information exchange network is expanded into the Internet, then employee of company outputs to the product information of this client's inquiry when the client inquires product information in distant on this client's the browser, this product information is added suitable explanation even also can receive at that time order with the locality.Therefore, estimate that this system can just promote in the mobile office chamber or family's work contributes.

Here, have as the application program Web Collaboration (network cooperation) that carries out these cooperations, it is the product of the applicant (IBM Corporation), be mainly used in and on Web server, share HTML and network cooperation snapshot shared (Web Callaboration Snap ShotSharing), it is the product of IBM Corporation, is mainly used in to share this machine image file.And, Web conference (Net Meeting) is arranged, it is the product of Microsoft company limited, be mainly used in and on various PCs, share an application program and freelance group screen display (Freelance Team Screen Show), it is the product of Lotus company limited, is mainly used in reading screen demonstration synchronously on the multiple pc machine.Such as, the service centre that is used for the client when the application program-network cooperation of IBM Corporation, when the information content of announcing on IBM Corporation's homepage is shared for each client, therefore can promote better to understand and be implemented between client that call center and so on play supporting role and procurator and communicate by letter smoothly.The demonstration of finding application program change and the operation that makes it to the Japanese patent application publication No. 9-258948 of the system that exerts an influence each other, as having announced in the patent gazette in Japan.

Yet, sharing functionality by HTML in Corepoint (trade mark of IBM Corporation) Web Collaboration, such as, though global HTML can both between browser, share because the content of document files is not announced on the webserver and can not be shared.And, though PDF (portable data formats) file on the webserver is shown, utilizing to insert pdf document is presented on the browser, the expansion of pdf document itself and rolling can not be synchronous.

Such as, certain procurator wishes to cooperate with the client with material, and it is no problem then only to be used in the material cooperation of announcing on the internet webpage.In fact, the material of only announcing with webpage can not prove absolutely in many cases.In these situations, announce on Web server that in advance material is unpractical.On the other hand, the general attorney does not upgrade the access authorization of Web server content, and the result is that this procurator has such problem: he can not immediately cooperate.

In existing application, the document files content of this machineization should not shared.For example, though existing application has bitmap is delivered to the function of Web server from a shared terminal, because the data volume of giving the webserver with bitmap format is huge, so WWW is transshipped inevitably.And, when the document files with multipage is converted to bitmap, need many labours.In freelance group screen display, also wish the shared document file.Yet group's screen display is an instrument that shows a plurality of freelance's data synchronously, so it can not share the document files of bidirectional operation.

And the patent publication No. 9-258948 of Japan only relates to window and shows sharing of changing unit, and the technology of wherein announcing is from the unresolved foregoing problems of crossing.

The present invention is intended to address these problems and the objective of the invention is effectively to share in other PCs of collaboration user and is stored in a document files in the PC.

Another object of the present invention is to cooperate effectively by collaboration server and user by a cache operations device.

A further object of the invention is to make the identical data formats storage of shared file with its source document.

The device that addresses these problems

At aforementioned these purposes, the present invention has a characteristic: the content of document files such as portable data formats (after this being called PDF) transmits and need not and can share by Web server from an end.

Specifically, characteristic of the present invention is, a cooperative system is arranged, and this system coordination is by the work between communication network user connected to one another, and this invention contains: session apparatus for establishing is in order to first user that sets up cooperation and the session between second user; Give described second user and need not pass through Web server in order to the document files content delivery that described first user is used with a file transfer means, because the session of setting up between first user and second user is set up by the session apparatus for establishing.

This cooperative system also comprises: file transfer requests device is used for requirement file is transferred to first user there and according to the file transfer means that requires the transferring documents file of file transfer requests device from second user.

The cooperation that has had this cooperative system just can be well on according to the document files of this machineization does not resemble and is used for URL in the present technology and can only instructs and move a position.

This cooperative system also comprises: a fileinfo dispensing device, the document files fileinfo that this device has first user sends to described second user.

There has been this cooperative system just can only be transmitted in the content that requires the document files of preservation a period of time in the file transfer.The best include file name of the fileinfo of the document file, file size, date or the like are so that identification this document.

Except above-mentioned configuration, also have the document files of opening between the user of cooperation device and move so that can send page or leaf in order to the session of synchronous foundation; The incident that expansion on page scrolling and the Any user reader/dwindle button is pressed and so on, so each user's viewing area can both be synchronous.

An embodiment of cooperative system of the present invention all provides the session apparatus for establishing in each links first and second users of communication network of the Internet and so on, but therefore transfer files.And, another embodiment can also be arranged, wherein remove the outdoor collaboration server in addition of first and second usefulness so that by this server cache and transmit this document and set up session.Certainly, the document file can adopt any file and form, so the document file is not limited to the document of narrow sense.And, PDF (portable data formats) file layout of wishing the data demonstration of U.S. Adobe System company limited exploitation is adopted as the document file format in this cooperative system, because PDF is used for general purpose and because the compression of this document is easy to transmission.

Here, the meaning of cooperation is, the action that user is taken place is passed to another user, and the action that another user is taken place also is passed to a user, and the result is the same in a word.

On the other hand, when understanding from the collaboration server angle between first and second users when of the present invention, collaboration server of the present invention has following characteristic: this collaboration server comprises a session manager to set up session by communication network between first and second users connected to one another; With a controller so that be received in the document files content opened first user there and give second user with the document files content of receiving from first user.For example, think that this collaboration server is suitable for crossing fire wall shared document file on PC.

This controller has following characteristic: this controller is received in the document files information in the document files of opening among first user and the document files information transmission received is given second user and further receive the document files content delivery that the requirement of transferring documents file and transmission requirement that response is received will open there from second user among first users give second user.When such as the time in second user's high speed buffer memory identical file, just needn't do the file transmission, and can prepare to share effectively the document file, therefore can in each user and collaboration server, pass through the caching function effective cooperation.

This collaboration server also comprises the content of a high-speed cache with the storage document files; Whether the document files information check document associated file content of receiving with basis with a cache manger is stored in the high-speed cache.If relevant document files content is to be stored in the high-speed cache then this cache manger is read the content of the document file there and it is transferred to second user from high-speed cache.Therefore, in cooperative system of the present invention, first user's file transfer process can omit.Particularly in cooperative system of the present invention, the file of data formats cache sharing that can be identical with its original file.Therefore, remove each with outdoor, also available collaboration server is made the requested of high-speed cache document files content.

The present invention is a kind of method of transferring documents file between a plurality of collaboration users, and this method comprises the following step: the document files of sharing is specified in the requirement according to the user; The fileinfo of the document files of report appointment; Receive the file transfer requirement in the document files; The file transfer of receiving with basis requires the transferring documents file content.For example, do not send from pdf document and this pdf document of a terminal and can share by Web server.By this document being converted to the rolling pdf document that PDF can alleviate the load of network and can expand pdf document synchronously and can not carry out by inserting existing browser.

The method of transmitting document files of the present invention comprises the following step: set up the session between client and procurator, this client and procurator are connected to each other by communication network; By setting up the shared document files of customer requirement transmission of session with this procurator; With requirement desired document files is transferred to this client and need not passes through Web server according to the transferring documents file.

The step of transferring documents file is that the document files content delivery that will there transmit from the procurator is given this client.Therefore, the former not material on WWW can be shared by the clerical worker and the client of corporate client call center window, to realize good contact.

Moreover the method for this transferring documents file also comprises the step of report from the fileinfo of clerical worker's shared document file.Such as, when identical file has been cached at this user there, can share the document file effectively.

In the present invention, in the storage medium of the program that storage is carried out by computing machine, this program allows computing machine carry out a session and sets up process to set up session, receiving process between a plurality of users of network so that process is that set up to be received the document files content that document files content and transmission process received by described receiving process with transmission there with users other user conversations and give other users that set up session with an aforementioned user from being set up by session linking.

In the present invention, in the storage medium of the program that storage is carried out by computing machine, this program allows computing machine carry out a process and specifies the document files of sharing with other users with the requirement according to the user, process with the fileinfo of the document files of report appointment, process to be identified in file transfer requirement in the described document files and a process to require the content of transferring documents file according to the file transfer that identifies.Can select any medium to make this storage medium.Such as, can adopt the medium of hard disk of being installed in the computing machine and so on and the CD-ROM of single storage medium such as the computing machine of program can being packed into.

When the present invention is construed to the program transmission equipment, the present invention contains: a memory storage is to store a program, this program allow computing machine carry out that a process requires with the file transfer in the identification document files with the fileinfo of the document files of specifying the document files of sharing with other users, a process report appointment according to user's requirement, process and a process to require transferring documents file content and a dispensing device that this program is read so that send from this storage medium according to the file transfer that identifies.Therefore the present invention can be used to give a PC etc. so that carry out this program there from the downloaded program of storing this program.

second users

10 and 11 each can both share URL to carry out the function of legacy network cooperation and so on other users, wherein this user can take out not the HTML of high-speed cache here from the webserver 31 theres.

Collaboration server 20 in the present embodiment comprises a session manager 21 in order to set up session according to first user 10 (being a clerical worker) or second user's 11 (being a client) connection request; With a session DB (database) 22 to store a pair of information that is connected.Collaboration server 20 further comprises a PDF high-speed cache 24 with the transmission with the control pdf document of the document files of high-speed cache PDF and so on and PDF cache manger 23.PDF high-speed cache 24 can be identical with source document the file of form cache sharing.Whether be stored in the PDF high-speed cache 24 once filename, size and the date check identical file of the transmission requirement PDF cache manger 23 of receiving transmission this document from the PDF high-speed cache.If this document is not cached in the PDF high-speed cache 24, then PDF cache manger 23 is had the user of pdf document to send to a file transfer requirement.If this document is cached in the PDF high-speed cache, then PDF cache manger 23 can transmit it.And collaboration server 20 also comprises the cache manger 25 of a WWW high-speed cache 26 and a control WWW high-speed cache 26.By the cache information of the URL that receives from a user there, collaboration server 20 selects to require Web server 31 transfer files or the transmission document files from network cache 26.Therefore can carry out traditional WWW collaboration feature.Collaboration server 20 can be operated so that can set up session by fire wall, and such

first user

10 and 11 of second users have realized cooperation by fire wall.

Below, with reference to the process flow process in accompanying drawing detailed description the present embodiment.

Fig. 2 is a process flow diagram, and it shows the process flow process of setting up the preceding collaboration server 20 of session in the present embodiment.It is as follows to describe these process flow processs with Fig. 1 and 2.The first, session manager 21 determines whether to send connection request (102 frame) by arbitrary user.If do not send connection request, then this step turns back to 101 frames (beginning), determines whether to have sent connection request again.If certain user has sent connection request, determine that then this user is procurator or client's (103 frame).If this connection request by the procurator (for example, first user 10) takes place, then this session manager 21 procurator that this procurator is added to session DB2 shows and reports to this procurator (for example, first user 10) to login successfully (104 frame).This step turns back to and begins place's (101 frame) and wait for that this client sends connection request.

On the other hand, be client's (for example, second user) if when 103 frames, determine this user, will determine to be that any procurator has logined this system (105 frame).If a procurator has logined this system, then this client (for example, second user 11) can and set up session (106 frame) with any procurator (for example, first user 10) pairing and report login success.After this, the thing of setting up session is reported to corresponding clerical worker (for example, first user 10) (107 frame), thereby finish the work of setting up (108 frame) of session.

If determine that when 105 frames still not having the clerical worker logins this system, then to this client (for example, second user 11) report failure, in other words, the procurator is not at (109 frame).This step turns back to and begins place's (101 frame), defines connection request does not take place.

Below, describe the process flow process set up after the session in detail until beginning to share document files such as PDF (the most characteristic part of the present embodiment) with reference to Fig. 1 and Fig. 3.In Fig. 3, the flow process of each process of having drawn, the process in process and second user 11 (being the client) the PDF control 13 in process, the collaboration server 20 in the PDF of the process of user action, the procurator's side control 13 among first user 10 (being the procurator) that drawn.Fig. 3 shows giving an example of this flow process, and wherein this procurator's suggestion is shared the document file with this client.In fact, can advise shared any one document files from procurator and client.

At first, in procurator's one side (first user's 10) PDF reader 15, open this machine pdf document (111 frame) from " opening " File menu.The file of opening appointment of PDF control 13 this machine of response pdf documents shows (112 frame).With the file that shows, " sharing beginning " button of pressing PDF reader 15 and provide the user of procurator's one side requires to begin to share (113 frame).Once receiving that this PDF that requires procurator's one side controls 13 and lights by the indicator of forming such as red light, expression is just being prepared sharing of document files and is being reported this document information (114 frame) to collaboration server 20.Collaboration server 20 is once receiving that the definite this document of this report is transferred to the destination of session manager 21 and fileinfo is transferred to client's side (second user 11) (115 frame).The PDF control 13 of client's side determines to be included in data the fileinfo that is transmitted or the like from the title and the size of file, determines whether that identical file is cached at (116 frame) in the PDF high-speed cache 24.If identical file is not cached at client's side, then PDF control 13 is to collaboration server 20 output file transmission requirements (117 frame).

Then, accept the collaboration server 20 of the file transfer requirement of client (second user 11) side and verify its data and session information from the title and the size of file, whether checking is that identical file is cached at 24 li of PDF high-speed caches (118 frame).If identical file is not cached at 24 li of PDF high-speed caches, then collaboration server 20 is to procurator's side (first user 10) demand file transmission (119 frame).The file (120 frame) of collaboration server 20 transmission requirements is given in the PDF control 13 that the reception file transfer of procurator (first user 10) side requires.The collaboration server 20 of reception file transfer confirms the transmission destination of session manager 21 and gives client's side (121 frame) with file transfer then.If determine that identical file is cached at (118 frame) in the PDF high-speed cache 24, then collaboration server 20 does not transmit to procurator's side demand file, and reads this document from PDF high-speed cache 24 theres, and this document is transferred to client's side (121 frame).When identical file high-speed cache, available this method is omitted the file transfer of procurator's side, and is shared thereby the short time is realized PDF.

Then, the PDF of client (second user 11) side control 13 receives file (122 frame) from collaboration server 20 theres, allows PDF reader 15 show the file of receiving then.Meanwhile, the pilot lamp of being made up of the blue lamp of analogy is lighted in PDF control 13, and expression has been ready to share and finish (123 frame) to the work that collaboration server 20 reports prepare to share.In aforesaid 116 frames, when checking identical file high-speed cache exist 24 li of PDF high-speed caches to the time, then the same mode of PDF control 13 usefulness shows that this pilot lamp represents that the preliminary work of sharing finishes.When checking identical file in 116 frames decisions is cached at 24 li of PDF high-speed caches, then can therefore can shorten a series of processing times of sharing greatly from omitting the transmission requirement process until PDF at 117 to 122 frames.Then, the collaboration server 20 that receives the report in 123 frames is determined to the transmission destination of session manager 21, and controls 13 report informations to the PDF of procurator (first user 10) side.The PDF control 13 that receives report is lighted by the pilot lamp of forming such as blue light, represents off-the-shelf sharing, and has therefore finished a series of until the process that begins to share PDF.In the above in the embodiment of Miao Shuing, because this transmission requirement is to give the user's and can any native mode begin to share by transfer files, just can cooperate immediately and use document files freely, not resemble present technology and be limited to content shared in the webserver.Certainly, client (second user 11) can require to share procurator (first user 10), as described above, and therefore, such as, can cooperate immediately according to the document files of on the client, preparing.Noticing that the cooperation here means will send to another user in the action that a user carries out and obtain identical result in another user by the same action that produces.

Next step is that it is synchronous to describe the action of carrying out after shared PDF begins with reference to Fig. 4.At first, Fig. 4 is a block diagram, and the synchronous configuration of carrying out in the present embodiment of action is described.The incident that all provides in the PDF of each first and

second user

10 and 11 control 13 monitors that parts 41 are to monitor that variety of event is such as supressing a button on the monitor, rolling, drawing or the like.One receives the information that incident monitors parts 41, then selects necessary information by incident control assembly 42.Specifically, such as, if adopt the vernier method of synchronization, then this incident is synchronous with the vernier move mode, i.e. whether incident control assembly 42 decision events are synchronous.Be defined as synchronous incident for incident control assembly 41, convert it to collaboration data by data conversion component 43.Data converted sends to collaboration server 20 from data unit 44 theres.

On the other hand, under the action situation of in the user of beginning shared document file, carrying out, carry out data and mail to Data Receiving parts 45 from collaboration server 20 theres.Data Receiving parts 45 receive this collaboration data, and event information converting member 46 converts this collaboration data to event information.Event action parts 47 are once receiving the various actions of carrying out PDF reader 15 from the output of incident information translation parts 46.

Next step is to describe the demonstration process flow of one page down with reference to Fig. 1 and 5, as synchronous the giving an example of action.

At first, 15 li of the PDF readers of procurator (first user 10) side, the click event of " following one page " button has taken place, this is user's a action (131 frame).The PDF of procurator's side controls 13 once receiving that this incident lights by the pilot lamp formed of analogy red colored lamp, and expression is just preparing to share, and allows PDF reader 15 show to descend one page and report the result to collaboration server 20 (132 frame).The collaboration server 20 that receives this report is determined to be dealt into the transmission destination of session manager 21 and is determined to the transmission destination of session manager 21 and to client's (second user 11) report information (133 frame) to the collaboration server 20 that client's (second user 11) report information (123 frame) receives this report.The PDF of reception this report of client's side control 13 allows PDF reader 15 show down one page and shifts the information (134 frame) of finishing to collaboration server 20 report pages or leaves.The collaboration server 20 that receives this report is determined to be dealt into the transmission destination of session manager 21 and is reported this information (135 frame) to the procurator.The pilot lamp of forming by such as blue lamp is lighted in the PDF control 13 of reception this report of procurator's side, and expression has been ready to share and finished the process that a series of one pages down show.

Here the demonstration of one page is as a synchronous example of action under describing.Yet the cooperation in the present embodiment is not only limited to the demonstration of next page.For example, can be to carrying out synchronously such as the size and the scroll actions of drawing straight line, the color that changes straight line or the window of A to B.For dealing with these situations, the collaboration server information among Fig. 5 of giving be changed over the action message such as drawing.In the present embodiment, alleviate the load of network by file conversion being become PDF.Can carry out synchronously expansion and the action the rolling such as pdf document, this is impossible inserting existing browser.And, can increase operation PDF is stored in that side that PDF is transferred to it.

Moreover, except that these are mainly operated, can also constitute this reader by the MDI interfacing that (many data interface)-company limited of a kind of Microsoft provides.This formation has been arranged, just can carry out the synchronous of a plurality of pdf documents.

Fig. 5 shows a kind of situation, wherein attempts one page under procurator's side (first user 10) shows.For in the opposite direction promptly showing one page down, can realize synchronously by similar treatment scheme from client's side (second user 11).

In the present embodiment, be described by being used in the collaboration server 20 that plays coordinative role between the user.Yet, can constitute a cooperative system so that save collaboration server 20 to set up session and directly a user to be linked on another user's IP address with the mode that allows each user (PC) all have the function of collaboration server 20.In particular, in each PC, by using such as Acrobat Core API and having the button of move page, rolling, expansion/dwindle and so on function to prepare the reader of pdf document.In addition, session is controlled the function of promptly setting up such as the network cooperation session and made a kind of liaison function to this reader.How the method for setting up session by this session control is similar to dialog box class (Chat Windows Class) and method such as " synchronously " and " by synchronously " is provided.Carry out synchronously with the method.In the present embodiment,, therefore needn't all prepare a control class for each browser of similar chat owing to there is not to use the control class of in IE and Netscape, using (WebWindow, IEWeb Browser).Next step increases an operation so that carry out FTP (file transfer protocol (FTP)) between PC, wherein sets up session.Specifically, when opening pdf document (wherein having set up session) by reader on any PC, then this pdf document is transferred to another PC and here shows.In the present embodiment, owing to only can transmit the pdf document page or leaf of appointment with Acrobat Core API, so can only open that one page that hope is opened to another user.Next step is, the file of opening is synchronous between the PC of having set up session.Specifically be exactly, move, roll and enlarge when press page or leaf in the reader on any PC/when dwindling button, then the zone observed of each user can be come synchronously by this incident being given another user.

As mentioned above, in the present embodiment, 11 of first user 10 and second users' message exchange (cooperation) is described.Can increase users in collaboration quantity so that at three or more this machine of shared among users file.For example, when cooperative system of the present invention is used for educational system far away as a kind of application, can consider to do such as do a kind of between teacher and many students exchange course or far educational aid and do a teacher and student between the instrument of course.If the present embodiment is used for this application,, can allow the student share the pdf document of teacher immediately for preparing on class because do not need on the webserver, to post in advance material.On the other hand, can also make up educational system far away so that the pdf document that certain student is prepared is shared immediately.Therefore can rewrite cooperation successfully between the user of webserver content in impotentia.

In execution the present embodiment has been installed during each functional programs, in the storage medium of CD-ROM and so on, the program that will be stored in then in this storage medium is read out by the readout device of (or be connected with this machine) during a computing machine is such as PC with this procedure stores of carrying out each process.Specifically, this program is installed among another user 10, the storage medium of second user 11 and collaboration server 20 usefulness CD-ROM and so on is carried out this program.Another kind method is this program can be downloaded to each user there by the Internet and so on.In this case, be configured with the PC class method transmitting apparatus of memory storage so that this procedure stores is got up to carry out aforementioned process so that this program is sent to each user by the Internet with the program dispensing device that is equipped with in the analogy PC.Particularly, when the present embodiment is used for the user and disperses in distant application, can allow the user have function in the present embodiment, method is to download this program, therefore can extensively make up cooperative system easily.

As mentioned above, by the present invention,, therefore can provide fast and at a high speed cooperation easily owing to need not the document files from a terminal can be sent to another terminal and share the document file each other by the webserver.
