CROSS-REFERENCE TO RELATED COPENDING PATENT APPLICATIONS  
       [0001]     The following patent application assigned to the assignee of the present invention and filed on Jun. 16, 2005, covers subject matter related to the subject matter of the present invention and is entitled: “A SYSTEM FOR CREATING MARKUP LANGUAGE DOCUMENTS AT A RECEIVING DISPLAY STATION HAVING MULTIPLE CONTENTS FROM MULTIPLE SECURED ON A COMMUNICATION NETWORK, E.G. THE WEB WITH VISUAL INDICATORS FOR IDENTIFYING CONTENT AND SECURITY”, Hately et al., (Attorney Docket No. AUS920050245US1), and copending Patent Application entitled: “A SYSTEM FOR CREATING MARKUP LANGUAGE DOCUMENTS AT A RECEIVING DISPLAY STATION HAVING MULTIPLE CONTENT PORTIONS FROM MULTIPLE SOURCES WITH IMPLEMENTATION FOR DISPLAYING THE STATE OF SETS OF CONTENT REVIEWS TO WHICH CONTENT PORTIONS SUBJECTED” (Attorney Docket No. AUS920050407US1), also assigned to assignee of the present Application and filed contemporaneously herewith.  
       TECHNICAL FIELD  
       [0002]     The present invention relates to a system, method and program for creating markup language documents, the contents of which are obtained from multiple sources from computer networks, such as the World Wide Web (Web) or Internet.  
       BACKGROUND OF THE RELATED ART  
       [0003]     The past decade has been marked by a technological revolution driven by the convergence of the data processing industry with the consumer electronics industry. The effect has driven technologies that have been known and available and relatively quiescent over the years. Two of these technologies are the Internet related distribution and object oriented programming systems. Both of these technologies are embodied in the use of object oriented technology and the Java programming system, in particular, for a wide variety of consumer and business purposes over the Internet or Web or like private networks.  
         [0004]     With the development and rapid expansion of the Web and other like networks, markup languages became the primary vehicle for distribution of data over such networks. A basic hypertext markup language, HTML, is described in detail in the text entitled Just Java, 2nd Edition, Peter van der Linden, Sun Microsystems, 1997, particularly at Chapter 7, pp. 249-268, dealing with the handling of Web pages; and also in the text, Mastering the Internet, G. H. Cady et al., published by Sybex Inc., Alameda, Calif., 1996, particularly at pp. 637-642, on HTML in the formation of Web pages. The Web pages are implemented so as to be used for the distribution of Web documents containing text, images, both still and moving, and sound, as well as programs.  
         [0005]     The rapid expansion of people, businesses and organizations with Web or Internet (used interchangeably) access has resulted in the widespread use of the Web for business, e.g. e-business and like electronic business, educational, medical and legal transactions. The complexity of the interrelationships involved in these transactions has made it common to handle and distribute Web or like private network documents having multiple contents respectively from multiple sources on the network. Such sources may be individual users at network display stations, as well as network databases that provide already developed and stored content. With the greater reliance on the impersonal network communication, there is less personal contact between the contributors of the content of these network documents. This makes it much harder for a participating user in a network transaction to recognize who contributed what to the document. The above cross-referenced copending application, “A SYSTEM FOR CREATING MARKUP LANGUAGE DOCUMENTS AT A RECEIVING DISPLAY STATION HAVING MULTIPLE CONTENTS FROM MULTIPLE SECURED ON A COMMUNICATION NETWORK, E.G., THE WEB WITH VISUAL INDICATORS FOR IDENTIFYING CONTENT AND SECURITY”, Hately et al., (Attorney Docket No. AUS920050245US1) provides an implementation for tracking, storing and displaying via visual indicators, the sources of the various content portions in any markup language document created or rendered from multiple sources.  
         [0006]     While this is an effective implementation in tracking Web or like network sources of document content portions, further problems are encountered when the document being created from multiple content sources has content portions that require sets of content reviews. The results of these content reviews are very important to both the host controlling the document sources, as well as to those creating the multiple content portions for the multiple content network document. In today&#39;s electronic commerce, for example, in the creation of network documents with content portions from multiple sources, the content portions of the variety of sources may have been subjected to sets of content reviews for many purposes. For example, a business company preparing to ship thousands of a specially designed and manufactured device may be generating a multi-content Web document having sets of reviews including approved legal reviews, approved accounting reviews, approved quality reviews, as well as time stamps and like commitments. Accordingly, in such multiple content portioned network, e.g. Web documents, it is important not only to be enabled to identify the sources of the portions but to be able to present to the user or viewer at a display terminal a user friendly Graphical User Interface (GUI) that shows the status of reviews.  
         [0007]     Consequently, “A SYSTEM FOR CREATING MARKUP LANGUAGE DOCUMENTS AT A RECEIVING DISPLAY STATION HAVING MULTIPLE CONTENT PORTIONS FROM MULTIPLE SOURCES WITH IMPLEMENTATION FOR DISPLAYING THE STATE OF SETS OF CONTENT REVIEWS TO WHICH CONTENT PORTIONS SUBJECTED” (Attorney Docket No. AUS920050407US1) provides an implementation for a user at a network display station who is reviewing or developing a network, e.g. Web document, that will easily indicate the status of sets of content reviews to which each content portion has been subjected to in a multiple content portion displayed document. A set of displayable non-alphanumeric visual indicators associated with each content portion, each indicator respectively representing the status of one of said set of content reviews. Then an implementation is provided enabling a user at the receiving display station to sequentially and collectively proceed through said sets of content reviews.  
         [0008]     While both of these two copending patent applications provide excellent visual aids for enabling the user of a Web document at a receiving display station to distinguish sources of content and current verification status of required reviews of received displayed Web Documents, we have recognized a need to separate the visual indicator data from the data content of the network, e.g. Web documents, so that verification, e.g. signature and time stamps, may be dynamically updated without intruding upon or entering the content of the network documents themselves.  
       SUMMARY OF THE PRESENT INVENTION  
       [0009]     The present invention offers an implementation for effectively visually displaying requisite review verifications for content portions of a displayed markup language, e.g. Web document, that verifications may be dynamically modified without altering document content. The invention is applicable to the network, e.g Web documents, of the above-mentioned copending Application wherein the document has content portions from multiple sources, as well as to network documents from single sources.  
         [0010]     Accordingly, there is provided a system for providing verifications on a markup language document, from a source on the network, received and displayed at one of said display stations comprising means for reviewing said markup language document at a display station remote from said receiving display station combined with means responsive to said reviewing means for providing review verifications for said reviewed markup language document. The implementation selectively superimposes a transparent displayed layer over said displayed received markup language document. Then there are means for indicating said review verifications of said displayed markup language document by non-alphanumeric visual indicators within said transparent displayed layer. The visual indicators may have specific colors.  
         [0011]     Preferably, the system provides for storing the content of said transparent layer independent of the storage of the content of said markup language document whereby the content of said transparent layer may be modified independently of the markup language document content. In this manner, the visual indicators may be readily modified responsive to changes in review verifications with affecting network document content even after the document has been transmitted to a user over the network.  
         [0012]     In a preferred embodiment, the network is the Web, and said document is created with XML protocols. Also, the markup language document may include multiple content portions, respectively, from multiple sources on said network and the review verifications are provided from sources on said network independent of said sources of said markup language document. Also, one or more of the review verifications may be a verified electronic signature.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0020]     Referring to  FIG. 1 , a typical data processing unit is shown that may function as the network display stations used for receiving the Web documents from multiple sources on the Web or function as the Web or network server computers for accessing each of the multiple contents from their sources on the Web in the present embodiment wherein the Web is the illustrative network. A central processing unit (CPU)  10 , such as one of the PC microprocessors or workstations, available from International Business Machines Corporation (IBM) or Dell PC microprocessors, is provided and interconnected to various other components by system bus  12 . An operating system  41  runs on CPU  10 , provides control and is used to coordinate the function of the various components of the computer of  FIG. 2 . Operating system  41  may be one of the commercially available operating systems, such as IBM&#39;s AIX or Microsoft&#39;s WindowsMe™ or Windows 2000™, as well as UNIX and other IBM AIX operating systems. Application programs  40 , controlled by the system, are moved into and out of the main memory Random Access Memory (RAM)  14 . These programs include the programs of the present invention for the use of visual indicators in a separable overlayer or template to represent the states of review verifications for the markup language document on the display screens of the receiving Web stations. These functions will be described hereinafter in combination with conventional Web browsers (browsers  53 ,  FIG. 1 ) at Web display stations  56  ( FIG. 1 ), such as Microsoft&#39;s Internet Explorer™. A Read Only Memory (ROM)  16  is connected to CPU  10  via bus  12  and includes the Basic Input/Output System (BIOS) that controls the basic computer functions. RAM  14 , I/O adapter  18  and communications adapter  34  are also interconnected to system bus  12 . I/O adapter  18  may be a Small Computer System Interface (SCSI) adapter that communicates with the disk storage device  20 . Communications adapter  34  interconnects bus  12  with an outside network. I/O devices are also connected to system bus  12  via user interface adapter  22  and display adapter  36 . Keyboard  24  and mouse  26  are all interconnected to bus  12  through user interface adapter  22 . It is through such input devices that the user at the Web display stations may interactively relate to the Web server programs for providing the markup language, e.g. hypertext documents of the present invention wherein color indicators are used to represent the states of review verifications for the markup language documents.  
         [0021]     Display adapter  36  includes a frame buffer  39  that is a storage device that holds a representation of each pixel on the display screen  38 . Images may be stored in frame buffer  39  for display on monitor  38  through various components, such as a digital to analog converter (not shown) and the like. By using the aforementioned I/O devices, a user is capable of inputting information to the system through the keyboard  24  or mouse  26  and receiving output information from the system via display  38 .  
         [0022]     A generalized example of the practice of the present invention wherein color indicators in a separable overlay layer independent of the underlying markup language (e.g. Web) document are used to represent the states of review verifications, accessed from sources on the Web, for statements and other content portions in the markup language document will be considered with respect to  FIG. 2 . It shows a generalized portion of the Web that serves as the illustrative communication network in this embodiment of the present invention. First, it should be helpful to understand from a more general perspective the various elements and methods that may be related to the present invention. Since the present invention is applicable to Web markup language hypertext documents, formed by multiple content portions, respectively from multiple sources on the Web, an understanding of the Web and its operating principles would be helpful. Reference has also been made to the applicability of the present invention to a global network, such as the Internet or Web. For details on Internet nodes, objects and links, reference is made to the above-referenced text, Mastering the Internet. (Web and Internet are used interchangeably in this description.)  
         [0023]     The Internet or Web is a global network of a heterogeneous mix of computer technologies and operating systems. Higher level objects are linked to lower level objects in the hierarchy through a variety of network server computers. These network servers are the key to network distribution, such as the distribution of Web pages and related documentation.  
         [0024]     Web documents are conventionally implemented in a markup language, e.g. HTML, which is described in detail in the above-referenced text, Just Java, particularly at Chapter 7, pp. 249-268, dealing with the handling of Web pages; and also in the text, Mastering the Internet, particularly at pp. 637-642, on HTML in the formation of Web pages. In addition, aspects of this description will refer to Web browsers. A general and comprehensive description of browsers may be found in the above-mentioned Mastering the Internet text at pp. 291-313. More detailed browser descriptions may be found in the text, Internet: The Complete Reference, Millennium Edition, M. L. Young et al., Osborne/McGraw-Hill, Berkeley Calif., 1999, Chapter 19, pp. 419-454, on the Netscape Navigator; Chapter 20, pp. 455-494, on the Microsoft Internet Explorer; and Chapter 21, pp. 495-512, covering Lynx, Opera and other browsers.  
         [0025]     Within this environment, Web Services distribution has evolved in recent years. Web Services are based on both suppliers of the data in the form of XML based messages and documents and applications consuming such data conforming to several industry standards developed by the W3C. The primary standard is XML (Extended Markup Language) for defining data and creating markup languages in the form of XML tags. The resulting XML documents are text based and, thus, may be processed on any platform in the distribution of the Web Services. In light of this background, reference is made to  FIG. 2  showing a portion of the Web or Internet set up for the distribution of text based data. Thus, data content in the form of HTML or other XML document portions may be transmitted over the Web and entered into receiving Web documents at receiving Web display stations. For purposes of the present embodiment, let computer station  56 ,  FIG. 2 , serve as a typical Web display station for receiving or sending Web documents. As will be described hereinafter with respect to the display interfaces of  FIGS. 3 and 4  and the programs of  FIGS. 5 and 6 , the received Web documents, either having content from a single source or multiple content portions from several sources, are displayed on computer display station  56  and the states of color indicators in the separable overlay layer independent of the underlying markup language (e.g. Web) document are used to represent the review verifications accessed from sources on the Web for statements and other content portions in the markup language document. This will be hereinafter described in greater detail with respect to  FIGS. 3 through 8 . Under the control of any conventional Web browser  53  in computer  56 , the desired Web document is accessed from its source or selected multiple data content-portions from multiple sources are combined into a composite Web document. The portion of the Web shown has four participating Web display stations  56 ,  45 ,  46  and  48 , with the latter three having associated databases  55 ,  57  and  58 . For purposes of this illustration, we are displaying a Web document from a single source  59  (source station  45 ) at Web display station  56  under control of Web browser program  53  operating via a conventional Web server system  51 , via the Web  50  to any of the multiple content portions from any of databases  55 ,  57  and  58 , respectively, associated with Web display stations  45 ,  46  and  48  or from input made by users at any of terminals  45 ,  46  and  48 , connected via Web servers, e.g. server  52  to Web  50 . The required review verifications, e.g. electronic “signoff” signatures, may come from functions operating throughout the Web, e.g shipping signature  49  output from display station  49  or legal signature output from display station  48 .  
         [0026]     It will also be understood that instead of any conventional Web server, system  51  may replaced by a server system of a service provider  47  that will conventionally perform this Web server function along with other Web service provider functions.  
         [0027]     As will be hereinafter described with respect  FIGS. 3 through 6 , the invention requires that the review verifications, e.g. electronic signatures, be combined into a transparent overlay layer or template to be superimposed on the displayed Web document. In this manner, the content of the overlay is independent of the Web document content so that the indicators in the overlay may be updated and changed as the status of reviews may change without affecting the Web document content. Thus, the data representing this overlay layer may be initially stored separate from the content of the Web document at the source of the Web document and sent along with the requested Web document. This verification overlayer content may also be stored at the receiving Web document station  56  or at the Web server  51  or Service Provider  47  supporting this receiving station. Such storage of the overlayer in connection with the receiving display station is particularly preferable when the Web document at station  56  is a composite Web document from multiple sources on the Web.  
         [0028]     It should be noted that in the dynamic processes of electronic business, when a Web document is received at a receiving station  56 , it may not have all of the needed review verifications, e.g. signatures. In such situations, the signature may be readily incorporated into the stored and displayed overlayer without changing the content of the underlying Web document. This would also be the case where there is change in a review verification.  
         [0029]     With reference to  FIG. 3 , the display screen  60 , as shown, has a displayed Web document at the stage where the document has been accessed and displayed together with its overlayer from a single source on the Web. For convenience in illustration, a single source document is illustrated. However, it will be understood that the principles of the present invention are equally applicable to multiple source documents as described in the cross-referenced copending Patent Applications.  
         [0030]     Content paragraphs  68  provide data relative to a shipment of widgets. This data is in the underlying Web document. The status of the various required review verifications  61 - 63 , i.e. the colored borders, are in a separate overlayer superimposed upon the Web document. These colored borders, each representing a different review verification status as defined in the bottom LEGEND, blue border  63  represents an illustrative shipping department (SP) verification; green border  62  represents an accounting (AC) verification signature; and red border  70  a verification signature (Rc) from the receiving department. It should be noted that the item: “Widgets are licensed under Zeon patent portfolio.” has no color indication of a review verification. Let us assume that a verification is due from the legal department. When such a verification finally arrives, only the overlayer will have to be changed to include an appropriate color indicator to reflect the legal verification.  
         [0031]     The “transparent” overlay  67  is diagrammatically shown in  FIG. 4  as separated from the underlying Web document  60 . It may be conventionally formed and displayed from the stored verification signature data by the text/graphics processor in the receiving display station in the same manner as if there were no Web document present and the display was blank. The only relationship that the text/graphics color indicators  61 - 63  have to the underlying Web document  60  is the spatial one shown in  FIG. 3 . This is illustrated in  FIG. 4 . The initial composite overlay of  FIG. 3  is shown separated into the basic Web document  60  of  FIG. 3  and transparent overlay  67  containing color indicators  61 - 63 .  
         [0032]     Now, with reference to  FIGS. 5 and 6  there will be described a process implemented by the present invention in conjunction with the flowcharts of these figures.  FIG. 5  is a flowchart showing the development of a process according to the present invention for use of color indicators in a separable overlay layer independent of the underlying markup language (e.g. Web) document to represent the states of review verifications, accessed from sources on the Web, for statements and other content portions in the markup language document.  
         [0033]     In a Web network with a plurality of interactive display stations for receiving and transmitting Web document content, provision is made for the display at an appropriate requesting station of a Web document having content contributed from a single or multiple Web sources including databases and other display stations, step  70 . Provision is made for the overlay of a transparent layer in the display superimposed over the received Web document, step  71 . Provision is made for the review of the Web document by requisite reviewers who provide review verifications, step  72 . Provision is made for the storage of the review verifications in step  72  separate and apart from the content of the Web document so as to be accessible to the Web document when the document is displayed, step  73 . Provision is made for the indication of the stored review verifications through visual indicators, e.g. colors arranged in the overlaying transparent layer, so as to indicate the review verifications and the underlying document content sections to which the review verification are applicable, step  74 . Provision is then made for indicating step  74  to be carried out when the underlying document sections that make up the Web document are from multiple sources, step  75 . Provision is made for the modification of displayed review verifications even while the overlaid Web document is displayed at a station, step  76 .  
         [0034]     An illustrative run of the process set up in  FIG. 5  will now be described with respect to  FIG. 6 . First, step  80 , a Web document is created at document source. The document is distributed for review to several reviewers who are required to input appropriate verifications, e.g. signatures, step  81 . Then, determinations are made as to whether a requisite verification has been received. If No, verifications are awaited. If Yes, then these verifications are stored as data for an overlay or template, step  83 . At this point, a determination may be made as to whether a Web document has been requested, step  84 . If No, the process is returned to step  82 . If Yes, the requested Web document is sent to the requesting station, step  85 , along with the stored states of the required review verifications for the Web document, step  86 . These verifications are embodied as color indicators in an over layer, step  87 . While the document and its overlay are being used at the requesting station, a determination is made, step  88 , as to whether there have been any changes in the document verifications, step  88 . If No, the process is returned to step  87 . If Yes, the change is effected in the stored reviews, step  89 , and these changes are sent to the display station that has the requested Web document, step  90 , where the changes are implemented in the overlayer without affecting the Web document, step  91 . At this point, a determination is made as to whether the user has closed the requested Web document, step  92 . If No, the process is returned to step  92  and use of the document is continued. If Yes, a further determination is made as to whether the session is over, step  93 . If Yes, the session is exited. If No, process is returned to step  82  via branch “A”.  
         [0035]     Although certain preferred embodiments have been shown and described, it will be understood that many changes and modifications may be made therein without departing from the scope and intent of the appended claims.
