Abstract:
An interactive electronic equipment document production system is disclosed. Documents from different sources are standardized in a conversion process, provided with tags in a tagging process that provides information connecting an initial locating with another location and are evaluated in a building process where tags and tag information are evaluated. Though the use of associated files, CAD files and generic pictures can be provided with tags and links without modifying the actual CAD file or generic picture.

Description:
FIELD OF THE INVENTION  
         [0001]    The invention relates to electronic documentation systems where the documentation is provided with links that allow a user to jump from one piece of information to a related piece of additional information. More in particular, the invention relates to a method for the automated generation of an Interactive Electronic Equipment Documentation (IEED) package for capital equipment.  
         BACKGROUND OF THE INVENTION  
         [0002]    Electronic documentation systems that include hypertext links for navigation purposes are well known. For example, an Internet page is typically provided with hyperlinks for navigation within a page and between other pages. Often, a hyperlink is displayed as a word or group of words that are offset from other words in the document by virtue of a difference in color. Additionally a special icon or picture can be associated with a word of group of words to set as a hyperlink. The ways to display a hyperlink are well known. Clicking on a hyperlink on a web page can jump to a different section on the web page or can open another Internet page. Other types of hyperlinks can be associated with files such as a sound file or a video file. Selecting a hyperlink can open the file allowing for a sound file to be heard or a video file to be viewed.  
           [0003]    Therefore, a hyperlink in an Internet page or electronic document written in a mark-up language such as the well-known hypertext markup language (HTML) allows for navigation between and within pages of a document and can open files associated with the link. Commercially available programs like Folio Views sold by Nextpage of Lehi, Utah provide much more sophisticated capabilities. In such a program, text documents can be provided with different types of hyperlinks, such as jump links, program links, query links, and script links. Jump links allow jumping to a predefined location in the same or in a different document. Query links display those parts of a document that comply with a query selection criteria. A program link can open any kind of document using its associated program. Script links can be used to trigger dedicated modules in a viewer program. To use these types of links, documents have to be prepared beforehand with the relevant link information like jump destinations, the selection criteria, and necessary labels pre-embedded. For an IEED system, the preparation of the documents and the creation of hyperlinks are a labor-intensive process. This is not as large a problem for the embodiment where the documentation is built once and stays the same for many users over a long period of time. However, it becomes very costly to create and maintain a documentation system when a large number of variations are included and material changes frequently.  
           [0004]    Unfortunately, the latter is the case in industries such as the semiconductor industry where expensive and complex capital equipment is used for the production of the semiconductor devices. The different pieces of equipment as used by different customers are normally not identical, since they contain either special production related parts particular to specific customers, or have to comply with customer requirements. Therefore, different IEED packages must be created for each customer. Since there is a definitive need for IEED systems, containing all the customer specific variations, it is necessary to use automated techniques to minimize the cost of creation of an IEED package.  
         SUMMARY OF THE INVENTION  
         [0005]    The objective of the present invention is to provide a method for building an IEED system in an automated way. This means to provide in a method for building an on-line documentation system, provided with hyperlinks and queries, collectively called links, that allows dealing with text documents in combination with drawings and other non-text documents and that can be build in a highly automated way. Another object of the invention is the creation of a browser, which allows simultaneous viewing of related information in the IEED system.  
           [0006]    According to the invention, the formation of the IEED package proceeds in three phases. First is a phase of providing documents in a known file format. This phase can comprise converting the provided documents, which can come from different sources and have a large number of different formats, into a number of predefined, standardized file formats. The provided documents with known file format or the converted documents with standardized file format are placed in a data storage. Unless the content changes, each input file will only be converted once.  
           [0007]    Next is a tagging phase. In this phase the standardized files are provided with tags, which will be used in a later stage to create a hotspot in the document and a hyperlink, activated by the hotspot. The hyperlink refers to a jump link, query link, program link, or a script link. These tags will be created automatically, based on a predefined tagging rule base. Tagging information can be stored either in the standardized file itself, or in a file associated with it. Output of this phase is stored in data storage. Each standardized file will only be tagged once, unless the content changes.  
           [0008]    The third phase is the building phase. In this phase all individual IEED packages, each called a project, are created. For a certain project, a building program automatically selects the required pieces of documentation from the data storage with standardized and tagged files, and creates the links between corresponding tags. The selection of required documents and the creation of the links are based on the information provided in the tags, and the instructions in the predefined builder rule base.  
           [0009]    Finally, to allow the use of an IEED package, a viewer is created using commercially available Active-X software components. The viewer will handle the display of the documents, which can have different file formats, and all the hyperlinking between these documents, in such a way that there is only one user interface, independent of the file formats being displayed. The viewer has a standard task bar at the upper side of the screen, and tabs at the lower side of the screen to switch from one functional part of the IEED package to another.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0027]    In industries, such as the semiconductor industry, capital equipment is used in the manufacturing process. This equipment is rather complex and costly. In order to ensure proper use and maintenance, each system is provided with an extensive set of documentation. Examples of information include customer information (customer name, address, contacts, etc.), equipment information (system type, serial number, etc.), equipment status information (maintenance info., etc), Bill of Materials (all assemblies and sub-assemblies), AutoCAD drawings, spare part information, pictures, manuals created by both the manufacturer and OEM supplier, and hardware and software release notes.  
         [0028]    Since it is convenient for both the manufacturer and the consumer to have this information in electronic form, a computer accessible documentation system is needed. Despite the fact that standardization is high within one family of equipment, each tool in the family of equipment has individual characteristics. These individual characteristics are due to the specific process to be run on the equipment or tool, or due to customer requirements regarding a certain brand of components to be build-in into the equipment during manufacturing. Consequently, the information and documentation associated with each individual tool, while partly general and common to each tool, are, to a great extent, tool specific.  
         [0029]    IEED packages, each with different content, are necessary for different purposes. For example, packages with information concerning maintenance and service support are required at different levels: for the customer (equipment on-site), for the field service engineer (equipment to be serviced), for the field service office (all equipment in a certain geographical area), and for the factory that manufactures the equipment (includes all equipment).  
         [0030]    Each deliverable documentation to a user is known as a project, which is in fact a specific selection of documentation regarding individual tools, which are included in the IEED package. A project should be completely self contained without links to other projects.  
         [0031]    To access the files relating to a project, two options are provided. First, the project files can be available on a central server and accessed via data connection lines or via Internet to remote computers or terminals. Alternatively, it is possible to store all the files relating to a project on a removable storage medium such as a CD-ROM or DVD-ROM. In this way, the files can be accessed locally on a computer.  
         [0032]    Below a step by step description of the formation of an IEED package for a project is given with reference to the appended figures. In one embodiment, the formation of an IEED package can be done on a single computer, such as a standard computer having and Intel or AMD processor and running an operating system such as Windows, Mac, OS, Linux and the like. Typically such a computer will be provided with a storage device for storing input files, intermediate files produced during the processing steps and final files produced to produce the final packages. The computer would also include standard components such as a monitor, keyboard and the like. In discussion of the formation of the IEED package the documents are provided to, processed by and results stored by such a computer. The functions of converting a document, tagging a document, and building a package are typically performed by software instructions running on the processor of the computer. However, these functions, while typically performed by a single processor can for convenience also be said to be performed by a conversion processor, a tagging processor and a building processor. Instead of a single computer, the tasks of converting, tagging and building as well as the components of the computer system can be distributed amongst multiple computer systems including those connected by local area networks, wide area networks, the Internet or any other method of distributive computing. The actual computer system used is unimportant; it is the novel method of formation of an IEED package that is important. The viewer program, to be described below, can similarly be implanted on a computer.  
         [0033]    Conversion/Standardization Phase  
         [0034]    First, with reference to FIG. 1, source documents  102 , needed to create the IEED package are provided. These source documents can be generated over a long period of time and can be supplied by various parties. A problem that often occurs is that similar information, coming from different sources, has different file formats. Also, a file&#39;s format may change over time as the producer of the file changes or upgrades software. Although in theory this can be solved, in practice, it appears a difficult problem to handle in an efficient way. According to the invention, as a first step after providing the source documents, the source documents  102  are converted into documents with a limited number of standard file formats as indicated in step  110 . The standardization of documents is done once by computer and the documents in standardized format are stored in storage for standardized documents  120  for further use. The storage can be any computer storage means including magnetic storage and optical storage. The conversion process is controlled using a conversion rule base  112 . Conversion rule base is a simple translation key that translates a known file format into a predefined, standardized file format. A processing program, using conversion rule base  112  converts the source documents  102  into the standardized file format. An advantage of this conversion is that for the rest of the building process the files that were from different sources and using different formats can be treated in the same way. Another advantage is that if the file format of a source document changes in the course of time, only the conversion program has to be changed. Therefore changes to the documents have no effect on the rest of the building process, after the conversion phase. Further, when new source documents using a non-standard file format need to be included into the IEED Package, they can easily be integrated into the system by building a specific conversion program with a new conversion rule base for this new source. Other components of the system such as the tagging system and the building system as well as the existing part of the database of standardized and tagged documents remain unchanged.  
         [0035]    Tagging Phase  
         [0036]    In a next step, step  130 , the standardized documents are provided with tags using a tagging program running on a computer in conjunction with a tagging rule base  132 . The tagging rule base  132  is for a large part based on the use of source files with a standardized file format as produced previously in the conversion phase. A standardized format and structure means that it is known where certain information can be found in the document or that certain information can be recognized from the format of the information. For example, a part number can be recognized either from the location of the part number in the document (such as in a Bill of Materials) or from the format of the part number itself (such as a string of a certain number of alpha-numerical characters in a manual) or from the combination of both. The tagging system and the build system recognizes the part number from its location within a document or format within a document and can mark the part number for further processing. Also, the structure of a document may facilitate the placement of tags. For example, a subheading in a table of contents could be a hyperlink to a subheading in the document. Whether it is a hyperlink to a subheading depends on the tagging rule base  132 . The tagging rule base  132  defines which tags need to be formed. These tags comprise information about where a hot-spot or click-button needs to be formed, and comprises parameters defining the destination of a link to be created in the building phase. Depending on the type of standardized document, the tags are either stored in the document itself or in an associated file. According to the invention, the creation of tags is preferably carried out automatically, using a predefined tagging rule base in combination with a known file format of the source documents.  
         [0037]    In one embodiment, three different categories of standardized tags are utilized. A tag can contain one or more parameters with each parameter defining the actions to be taken in the building phase. The first category of tags is predefined tags. Predefined tags are tags wherein a link that must be formed is uniquely defined. Examples are a jump link or a query link. The second category of tags is tags that are subject to verification. The link destination for such a tag subject to verification is defined, but during the building phase it will be decided if the link will be created or not. This category of tags is used in cases where the link destination might be missing. The third category of tags is tags that contain variables as parameters. These parameters are evaluated and the variables are filled in during the building phase. For the third category of tags, in the building phase it is not only verified if a link should be formed or not, but also the exact link destination of the link to be formed is defined, based on the parameters provided in the tag.  
         [0038]    As is further explained in the following figures, tags of a certain category can be converted in the building phase into more defined tags of a lower category prior to the actual formation of the links. Some examples of tagging of documents include:  
         [0039]    (1) In manuals, tags of the first category can be formed based on chapter headings, catchword, or other information. For example, tags in the document can be made on the text “see Figure” or “see Chapter”, so that in a later stage the links to the proper figures and chapters can be automatically made.  
         [0040]    (2) The structure of a piece of equipment is described in the Bill of Materials (BOM). A BOM starts with an information block, describing the top-level assembly of the equipment and the composing subassemblies. For each sub assembly a similar structure is available. This is repeated until no further assemblies exist, resulting in a hierarchical structure of the equipment. At the time of the file tagging it is not known which parts in the BOM should be considered as spares. Therefore all parts will be tagged with a spares tag, which is a category two tag. During build time it is checked if the part is indeed a spare. If it is, a link to the spare parts list is created. If not, the no link is made and the tag is discarded.  
         [0041]    (3) New documentation is created and added over time. The linking of documentation to parts in the BOM is therefore an action that cannot be fully determined at tagging time. Therefore, parts in the BOM are provided with documentation tags in category three, with the part number as parameter. During build time the builder rule base determines which links have to be created, based on the parameter value.  
         [0042]    (4) Different parts on a CAD drawing are labeled by so-called “find numbers” which are a circle containing a number. The tagging program will create category three tags for these “find numbers”, each tag having a find number, its location on the drawing, and a drawing identification as parameters. The tags are stored in a separate file, associated with the CAD drawing file. This is advantageous because the drawing file format stays the same with link information stored in an additional associated file. The drawing identification and the find numbers can also be found in the BOM. Based on the associated file, the builder can create links between the CAD drawing and the BOM.  
         [0043]    After tagging, a tagged document is stored in the tagged document storage for further use. This storage forms the source of documents from which each project to be built. Each tagged document is only included once in this storage. The tagging phase, in which tags are created, is distinct from the building phase, in which the tags are used to create links.  
         [0044]    Building Phase  
         [0045]    Before the building process can start, a project definition  150  needs to be provided. The project definition  150  defines the scope of the project i.e. the specific selection of individual tools for which the IEED package should be made. This project definition  150  specifies at a first level which documents from the tagged document storage are required for the formation of the project. Further documents will be included, depending on the information in the tags. The project definition is created using a master database  152 , which contains information regarding tools, equipment and customer information. The equipment information contains the serial number, configuration information and the customer identification for each tool. The customer information contains customer identification, such as the name of the customer and the customer&#39;s address. The customer information makes it possible to select all customers located in a certain city, country, or geographical region. In this way a project can very quickly be defined to include all equipment for the customers in a certain area. Although project definition will be primarily done through customer selection, other possibilities exist. It is possible to make an equipment selection based on equipment type, or based on all equipment still under warranty, or all tools comprising a subassembly with a certain part number and revision number. Obviously, for such a different selection criterion, the master database  152  contains the relevant information. The project definitions are stored in the master database  152  to facilitate recreation of projects in the future.  
         [0046]    In step  160 , a project is built using a building process in conjunction with a build rule base  162 . Building a project, after providing a Project definition, starts with the selection of the required documents from the storage of tagged documents. The Project Definition specifies at a first level which documents from the tagged document storage are required for the formation of the project. Further documents will be included, depending on the information in the tags. The selection mechanism ensures that each document is only selected once, even if multiple references to the same document are present. For example when a part is present “n” number of times, the corresponding CAD drawing for this part is only included once. Or when the project comprises multiple identical tools, the applicable manuals for that tool are included only once. Different revisions of an object are considered to be non-identical, and therefore for each revision present, the applicable documents are included in the project. An exception to the rule of avoiding duplicate information is the bill of material (BOM) information; it is allowed to have duplicating information about sub assemblies stored in BOM&#39;s for different tools.  
         [0047]    The builder rule base controls the activities of the builder and describes the activities to be carried out. In the first phase of the building process after the selection of the required documents, all category three tags are converted into category two tags. The parameters in the category three tags are interpreted and combined with information from documents such as the BOM. The result is that all tag parameters are replaced by known values. This means that the tags are converted to tag type two.  
         [0048]    In the next phase of the building process, for each category two tag, it is checked if a successful link can be created. If so, the tag is converted to a category one tag. If not, the tag is removed as being not applicable.  
         [0049]    When the final stage of the building process starts, the documentation contains only category one tags. The builder continues with the final stage of the building process. In this final stage, all the tags are converted into links and final output files are created which contain all the highlighted word links, “hot-spots” or click-buttons, and the linking information. In the formation of the link, information stored in the tag will be used. In the majority of the cases, the part number plays an important role. By using the part number as a parameter in the tags, the link formation process can be automated. Other parameters can be used for the same purpose.  
         [0050]    The format of the output files may be hypertext markup language (HTML), extended markup language (XML) or any other hyperlink language. Output files may also be in one or more proprietary formats that can be viewed on a viewer program. At the end of the building phase, files can be compressed so that they can be stored more conveniently. Files may also be encrypted to restrict access to the information to authorized users. As a last step in the building process, the IEED Package  170  is formed by storing all of the output files needed on a storage medium. The files can be distributed on CD-ROM, DVD-ROM or other media.  
         [0051]    For several reasons, it can be necessary to update the project over time. This could be due to enhanced user documentation, expansion of the installed base, or modification of the installed equipment. To update to a new project, the necessary new or modified input files need to be provided, and subjected to the conversion and tagging steps so that the corresponding standardized and tagged files can be added to the library of standardized and tagged files. Then the build process is executed again. Finally, the user needs to be given access to the updated files, e.g. by storing the files on CD-ROM and making the CD-ROM available to the user.  
         [0052]    The standardization of documents will be further described with the aid of FIG. 2. FIG. 2 is a block diagram illustrating different types of documents that are standardized. Illustrated are different document types  202 - 208 . Document types may include a bill of material, AutoCAD drawings, spare parts list, and various manuals developed by either the manufacturer or by an OEM supplier any stored in one of any number of formats. Any other documents or document types may be used also. Each document type  202 - 208  has an associated conversion program  210 - 216 . Each one of the conversion programs  210 - 216  is designated to convert its associated document type to one of a number of standardized documents  218 . Although the conversion programs are indicated in FIG. 2 as multiple dedicated modules, it is possible to combine part or all of the modules into one conversion program. Also, in cases where a company has multiple subsidiaries at different geographical locations that each produce a variety of documents, specific conversion programs can be used for each subsidiary, if needed. The respective subsidiaries can also be interconnected in any feasible way such as via a local area network or wide area network.  
         [0053]    [0053]FIG. 3 is a block diagram of the master database  152 . FIG. 3 shows a master database  152 , which includes an equipment database  304 , a customer database  306 , and a project database  308 . Equipment database  304  contains configuration information for each piece of equipment. This includes for each piece of equipment: the machine type, the top level BOM part number, and the customer location to which it has been or will be supplied. Customer database  306  comprises additional information concerning customer locations, addresses, contacts and the like. The customer database  306  makes it possible to select all the customers located in a certain city, country, or geographical region. Finally, the project database  308  comprises a number of project names and connects each project name with one or more customer names. In this way, a project can be very quickly defined for all the customers in a certain country or region. In one embodiment, the project definition is done primarily through customer selection. However, project definition can also be done in a different way, such as being based on equipment type, or being based on all tools delivered in a certain time period, provided that the information used to perform the selection is present in the master database.  
         [0054]    [0054]FIGS. 4 and 5 are block diagrams illustrating the creation of a jump link. FIG. 4 shows two documents  402  and  404  that relate to a project. Document  402  contains a tag  406  and document  404  contains a marker  408 . The marker  408  defines a location in the document  404  to which a jump link is made. The marker  408  needs to be provided in the source document. When the tag  406  is included in the document  402 , the location of the tag  406  is the location of the hot-spot or click-button to be formed. When the tag  406  is not included in the source document itself but in an associated file, the tag  406  in the associated file contains information about the location and size of the hot-spot or click-button to be formed in the source document. Further, the tag  406  contains the following information: link type (such as jump), and link destination. The information relating to the link destination can include the document to which a link should be created, and parameters that depend on the link type. In case of a jump link, the tag comprises the jump destination within the document as a parameter. The builder checks if the requested document and destination are available. If this is the case, as seen in FIG. 5, a click-button  502  is formed in document  402 , according to information contained in tag  402 , and a hyperlink  504  is formed from document  402  to the marker  408  in document  404 . Click button  502  is typically formed by highlighting the word or phrase associated with the jump link. Also a button or other icon can be provided. The marker  408  can be in a document different from the document wherein the tag is, as shown in FIG. 4 and FIG. 5, or the tag  406  can refer to a marker  408  within the same document as the click-button. Working with markers is possible within the scope of the present invention, in particular when jumps are made within one document. However, the full advantages and flexibility of the present invention become apparent when using query links as described below.  
         [0055]    [0055]FIGS. 6 and 7 illustrate the formation of a query link. Again, two documents  610  and  620  are provided as part of the project. The tag  611  in document  610  contains information regarding link type (such as query) and document to which a link should be created. In this case, the tag  611  further comprises one or more parameters, which are translated into a query syntax during the building phase. The parameters can comprise a certain word or a part number to be searched for in the body of the document. Further the query, to be executed on the linked document, can comprise a combination of search terms or other conditions. By execution of the query, all sections of the linked document that fulfill the criteria of the query will be highlighted. In the building phase, the builder checks if the requested document  620  is available. If this is the case, a click-button  712  is formed in document  610 , according to information contained in tag  611 , and a hyperlink  730  is formed from document  610  to document  620 , as seen in FIG. 7. In the preferred embodiment, the query will be executed every time that the user activates the click-button  612 .  
         [0056]    [0056]FIGS. 8 and 9 describe the use of an associated file to store click-button and tag information for documents like AutoCAD drawings where the file format has to be retained. For AutoCAD files and other drawings or illustration files, the original file format has to be maintained. Consequently, it is not possible to store click button information and tags directly in the file. Therefore an associated file  815  is used, which is associated to the original file  810 . In the associated file  815 , information  811  is stored defining an area  814  in the picture to serve as the click button. Further, the information  811  comprises information regarding the action to be taken when the click button is pressed. The project further includes destination document  920 , which contains a marker  925  marking the destination of a link as seen in FIG. 9. Document  910  is linked to the marker  925  in destination document  920 . Using the information contained in tag  811 , the builder checks if the requested document and destination are available. If this is the case, the tag  811  is converted into the hyperlink  930 , linking associated file  815  to document  820 .  
         [0057]    During the viewing process, the viewer program will track mouse or other pointing device movements (including the touching of a touch screen). If the mouse or other device is selected or clicked when the pointer is within the area  814  (as determined by the information in the associated file  815 ), the viewer program reads the associated file  815 , and executes the found hyperlink instruction. For example, document  810  can be an AutoCAD drawing of a subassembly showing a plurality of parts wherein each part is provided with a so-called drawing position number or “find number”. A find number is a circle containing a number. Consequently, the associated file  815  comprises a list of the find numbers used and for each find number an area  814  corresponding with the circle in the AutoCAD drawing. Further, the associated file  815  comprises for each find number information specifying a link to be made like a link to another document  820  such as a bill of materials, or a close up of the art. Selecting the circle of the find number in document  810  corresponding to a part causes the viewing program to read the associated file  815  to determine what action to take, such as viewing the Bill of Materials or a more detailed AutoCAD drawing of the selected part.  
         [0058]    [0058]FIG. 10 shows the use of hyperlinks on generic picture files where the original picture format needs to be retained. If the original picture file format has to be retained, it is not possible to store click button information and tags directly in the file. Therefore, an associated file  1015  is used, which is associated to the original picture file  1010 . In the associated file information  1011  is stored defining an area  1014  in the picture that will serve as the click button. To minimize the amount of creation and maintenance work for the IEED package, it is advantageous if a generic picture file  1010  and the associated file  1015  can be reused for different tools in different projects. Therefore, the information  1011  includes a generic tag with a generic parameter. For example, the generic tag may be “reactor” which can refer to a number of different reactors, such as atmospheric reactors and vacuum reactors. In the building phase, link file  1035  is created which specifies the machine specific actions for the generic tags. So, if the specific machine is an atmospheric reactor, link file  1035  will refer to that type of reactor. Link file  1035  contains label  1036 , which refers to the generic tag  1011  in associated file  1015  and a tag  1037 . The project further includes document  1020 , which contains marker  1025 . The builder program checks, based on the information contained in tag  1037 , if the requested document and destination are available. If this is the case, the tag  1037  is converted into the hyperlink  1032 , linking file  1035  to document  1020 . When the area  1014  is clicked, the viewer program will read the associated file  1015  and the link file  1035  and execute the found hyperlink instruction. This way of dealing with pictures creates a very flexible system, which requires very little manual work. An advantage of this technique is also that for a project only a limited number of pictures are required, therefore reducing the needed memory space considerably. Obviously, a picture can comprise a plurality of click buttons and links.  
         [0059]    [0059]FIG. 11 shows an example of a number of linked documents. For simplicity reasons, no files with an associated file or a link file are included. Four documents,  1110 ,  1120 ,  1130  and  1140  are shown. With  1112 , a click button with two possible link destinations is indicated. In such a case, after clicking the button, a pop-up screen appears, offering a selection between the available link destinations. With  1125 , a link destination is indicated that can be reached from various departure points.  
         [0060]    According to the present invention, the process of project formation is fully automated, and therefore does not require a great effort. Great advantage of this procedure is that the documents relating to additions or modifications are fully integrated into the IEED package, complete with all the desired hyperlinks.  
         [0061]    The completed IEED package can be viewed by a user using viewing software. In one embodiment the viewing software is built around a number of commercially available ActiveX software components. Those components allow the viewing of different file formats. The viewing program is designed to run on a computer, stand alone or networked, that includes a processor and memory such as an IBM compatible computer with an Intel processor and running the Windows operating system. Further, this computer includes a user interface such as a monitor and a keyboard or a touch screen to display and to navigate through the information relating to a Project.
