Abstract

A method and apparatus for a structure editor implementing a 'top-down' approach to designing a Web page. The user uses a 'drag and drop' interface to add, delete, and move display elements to define the hierarchy of the site and to define the layout of each page in the site. The present invention automatically generates a layout for each page. This layout contains display elements that represent the links between pages of the site. The present invention automatically adds, removes, and deletes the appropriate links between the pages of the site as the user moves display elements. After the user has defined the hierarchy of the site and the layout of each page in the site, the user 'publishes' the site. The publish function automatically generates HTML for each page of the site in accordance with the display elements of each page, yielding true WYSIWYG pages for the site.

Description

HIERARCHICAL STRUCTURE EDITOR FOR WEB SITES
FIELD OF THE INVENTION
This application relates to the World Wide Web and, in particular, to a method and apparatus for managing elements of a World Wide Web site having multiple pages.
BACKGROUND OF THE INVENTION
The past several years have seen an explosive growth of the World Wide Web ("the Web"). The Web is built around a network of "server" computers, which exchange requests and data with each other using the hypertext transfer protocol ("http"). A human designer designs the layout of a
Web page, which is then specified using HTML ("Hypertext Markup Language") . Several versions of HTML are currently in existence. Examples include HTML versions 2.0 and 3.0, as specified by the WWW Consortium of
MIT. Netscape Communications Corp. has specified additional HTML features
that extend the HTML language, including forms and tables.
A user views a Web page using one of a number of commercially available "browser" programs. The browser submits an appropriate http request to establish a communications link with a Web server of the network.
A typical http request references a Web page by its unique Uniform Resource Locator ("URL"). A URL identifies the Web server hosting that Web page, so that an http request for access to the Web page can be routed to the
appropriate Web server for handling. Web pages can also be linked graphically to each other. The HTML to describe a Web page is often created by hand by a human
being. If the design of the page changes, the corresponding HTML must be rewritten, which is an exacting process. Although several conventional HTML editors exist, these editors only allow the user to specify certain elements of a
page and still require the user to enter HTML code. Conventional HTML editors
allow the user to specify the page content and general layout, but do not provide the user with "What You See Is What You Get" (WYSIWYG) capability. Thus, the pages generated by conventional HTML editors look different when
viewed by different browsers.
A Web "site" consists of a "homepage" and several other related pages. Each page has corresponding HTML that describes the appearance and function of the page. For example, the HTML for the homepage usually contains links to one or more of the other pages and the other pages often contain respective links back to the homepage. When the user clicks on a link of the displayed homepage, the browser requests and displays the linked-to
page. Each link must be designed and coded into the HTML for the page.
Thus, for example, when a human designer decides to remove a link between the homepage and another page, the HTML for the homepage must be changed to reflect the removed link. This process is exacting and requires that the user
manually change the link. Moreover, if the linked-to page has another link back
to the homepage, that link may also need to be changed.
It is usually desirable to have a consistent style for all pages of a site. When the user hand codes the HTML for each page of a site, it is difficult for
the user to remember to use a consistent style. In addition, if the user decides to change the style of a site, each page must be changed individually.
SUMMARY OF THE INVENTION
The present invention overcomes the problems and disadvantages of
the prior art by using a "top-down" approach to designing a Web page. The user can use a "drag and drop" interface to move icons representing Web pages into a desired hierarchy of pages for the site. The hierarchy can, but does not necessarily represent links between the pages of the site.
The user drags and drops display elements to define the hierarchy of the site and to define the layout of each page in the site. The present invention automatically generates a layout for each page. This layout contains display
elements that represent the links between pages of the site. Thus, the user
does not have to manually specify links for each page. As the user drags and drops icons to add, move, and delete pages of the site hierarchy, the present invention will automatically add, remove, and delete the appropriate links
between the pages of the site. A preferred embodiment also automatically
creates a banner across the top of each page that contains a user-specified page name.
After the user has defined the hierarchy of the site and the layout of
each page in the site, the user "publishes" the site. The publish function
automatically generates HTML for each page of the site in accordance with the display elements of each page. In the described embodiment of the present invention, the publish function generates an HTML table for each page. The
number of cells in each table reflects the number and placement of display
elements on a corresponding page, yielding a true WYSIWYG page for the site. In accordance with the purpose of the invention, as embodied and
broadly described herein the invention is a method of allowing a user to define a World Wide Web site having a plurality of pages with a hierarchical organization comprising the steps, performed by a data processing system, of:
receiving an indication that the user wants to add a new page at a position in
the site hierarchy; adding a page data structure for the new page to a tree of other page data structures reflecting the site hierarchy, where the page data structure is added in accordance with the position of the new page in the site
hierarchy; and automatically creating in the memory a layout data structure for
the new page, the layout data structure having a link in accordance with the position of the new page in the site hierarchy.
In further accordance with the purpose of this invention, as embodied
and broadly described herein the invention is a method of allowing a user to
define a World Wide Web site having a plurality of pages with a hierarchical organization comprising the steps, performed by a data processing system of:
displaying a plurality of page icons in a hierarchical fashion, on a display device
where the hierarchy of the page icons reflects the hierarchal organization of the pages; receiving an indication that the user has dragged one of the page icons in the site hierarchy from an old position to a new position; displaying, in accordance with the new position, an indicator on a second page icon
indicating where the new page icon would be added in the site hierarchy;
receiving an indication that the user wants to move the new page to the new
position; removing the page icon from the old position on the display device;
displaying the page icon in proximity to the indicator; and moving a page object, corresponding to the moved page icon, within a tree structure in accordance with the new position of the moved page icon.
Advantages of the invention will be set forth in part in the description
which follows and in part will be obvious from the description or may be learned by practice of the invention. The advantages of the invention will be
realized and attained by means of the elements and combinations particularly
pointed out in the appended claims and equivalents.

Reference will now be made in detail to a preferred embodiment of the invention, an example of which is illustrated in the accompanying drawings.
Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.
I. System Overview
Fig. 1 is a block diagram of a computer system 1 00 in accordance with a preferred embodiment of the present invention. Computer system 100
includes a CPU 1 02; a memory 1 04; input/output lines 1 05; an input device
1 50, such as a keyboard or mouse; and a display device 1 60, such as a display terminal. Computer 1 00 also includes an input device 1 61 , such as a floppy
disk drive or CD ROM reader, that reads computer instructions and data stored on computer readable medium 1 62, such as a floppy disk or a CD ROM. These
computer instructions are the instructions of e.g., structure editor software 1 20. Memory 104 includes structure editor software 1 20, page objects, layout objects, and draw objects 1 30, HTML 1 40, and image files 1 40, etc., as described in further detail below.
A person of ordinary skill in the art will understand that memory 104 also contains additional information, such as application programs, operating
systems, data, etc., which are not shown in the figure for the sake of clarity.
It also will be understood that computer system 100 can also include
numerous elements not shown in the Figure for the sake of clarity, such as disk drives, keyboards, display devices, network connections, additional memory,
additional CPUs, LANs, internet connections, input/output lines, etc.
II. Site Creation and Manipulation
The following paragraphs describe how the user creates a hierarchy of
pages for a site. It will be understood that all flow charts in this document represent steps performed by processor 1 02 executing instructions of structure
editor software 102.
Fig. 2 is a block diagram showing input and output to structure editor software 1 20 of Fig. 1 . Structure editor 1 20 includes a portion 202 that creates and manages a hierarchy of pages and a portion 204 that publishes the pages of the site. The user uses a drag and drop interface to define the
hierarchy of the site. Pages in the site can include new text and images or
preexisting text and images. The user initiates publish portion 204 by clicking on a "publish" button as described below. Publish portion 204 generates a
plurality of HTML pages, as described below. Each page includes one or more
HTML tables that yields a WYSIWYG Web page.
Fig. 3 shows a "site view" displayed on display device 1 60. In the described embodiment, the display of Fig. 3 is displayed by processor 102
upon beginning execution of structure editor software 1 20. The site view of
Fig. 3 is also displayed when the user selects Site button 302. Fig. 3 shows that the software automatically creates a node representing a "Home" page and displays an icon 350 corresponding to the home page node.
The display of Fig. 3 includes a plurality of buttons: a "Site" button 302, a "Page" button 304, a "Style" button 306, an "Assets" button 308, and
a "Publish" button 310. The display also includes a "Preview" button 31 2, a
"New Page" button 314, a "Goto" button 31 6, and a "Last" button 31 8. Each of buttons 302-31 4 are discussed below in turn. The Goto and Last buttons 31 6, 31 8 transfer control to a most recent display or a user-selected previous
display, in a manner known to persons of ordinary skill in the art. The
described embodiment keeps a "history" of execution of structure editor 1 20 in order to implement the Goto and Last buttons.
The display of Fig. 3 further includes a "Structure View" toggle 320
and an "Outline View" toggle 322. When the user clicks on Structure View
toggle 320, a display having a format of Figs. 3 and 4 are displayed. When the user clicks on Outline View toggle 322, a display having a format of Fig. 6 are displayed. The user can drag and drop page icons in either the Structure view
or the Outline view.
The display of Fig. 3 further includes a "Tools" window 324. Tools window 324 includes a "cursor" tool, and "zoom in" and "zoom out" tools, as
are known in the art. Depending on the implementation used, windows are
also called "dialog boxes."
The display of Fig. 3 further includes a "Properties" window 326. Properties window 326 includes three tabs: a "View" tab 328, a "Site" tab 330, and a "Page" tab 332. Properties window currently shows page
properties because page tab 332 is selected. Properties window 326 includes
a "Name" area 334, a "Page Type" area 336, a "Publish/Don't Publish" area 338, a "Color" area 340, a "Status" area 342, and a "Comments" area 344. The user can "select" a page icon, such as page icon 350, in a manner known to person of ordinary skill in the art. When a page icon is selected, the
values shown in Properties window 326 are values for the selected page.
Thus, in Fig. 3, when "Home" page icon 350 is selected, the name field in
Properties window 326 is "Home." The page type is "normal." ("Stacked pages" are discussed below). The user has indicated that the page should be published during the Publish function. (The user also can indicate that the page
should not be published during the publish function). The color of page icon
350 is the color indicated in Color area 340. (Note that this is different from the background color of the page itself.) The user has indicated that the status of the page is "not done." The user has not entered any comments about the page. It will be understood by persons of ordinary skill in the art that structure editor software 1 20 stores values corresponding to Properties window 326 and for each Properties window and Properties tab discussed herein in memory
104. Fig. 4 shows a second display on a display device generated in accordance with the embodiment of Fig. 1 , where the user has added multiple pages to the site and one page has been moved from its original position. In
Fig. 4, the user has added page icons 452-474 by selecting (e.g., clicking) on
New Page button 31 4 for each new page icon added. Each new page icon
represents a new page added to the site hierarchy. The site hierarchy uses a
"tree" structure. Each branch of the tree represents a "logical" (or "structural")
connection between two pages. As discussed below, these logical connections
may also represent links between the pages, but do not necessarily represent such links. Moreover, links between pages may exist that do not represent
branches of the site hierarchy.
Fig. 4 shows a display after the user has selected page icon "Files" 466 and dragged page icon 466 on top of page icon 474. The dotted line in Fig. 4
indicates the path of the dragged page icon, but is not displayed. In the
described embodiment, page icon 466 is highlighted when it is selected. When a page icon is dragged, it is represented by a dotted outline of a page icon (not shown). As shown in Fig. 4, when the user drags a first icon on top of a second icon, the first icon is displayed with an arrow indicating where the
second page icon will connect to the first page icon. Thus, in Fig. 4, if the user drops page icon 466 on top of page icon 474 (and slightly below icon 474), page icon 466 will be displayed as "child" of page icon 474 (and removed from its previous display location). Fig. 1 7 shows another example of moving a
page icon so that it becomes a child icon. Fig. 1 8 shows an example of moving a page icon so that it becomes a sibling page icon. If, in Fig. 4, page icon 466 was moved to the left side of icon 474 instead of to the bottom, an arrow would appear on the left side of icon 474, indicating where the page
icon 466 will connect to page icon 474 if it is dropped. Thus, in Fig. 4, if the user drops page icon 466 on top of page icon 474 (and slightly to the left, not shown), page icon 466 will be displayed as "sibling" of page icon 474 (and removed from its previous display location).
Fig. 5(a) show an example of an internal representation of page objects corresponding to the page icons of Fig. 4 before page icon 466 is moved. Page objects and page icons are also called "nodes." The page objects of Fig. 5(a) form a tree data structure in memory 1 04. Page object 502 is a child of a
"Private" page object 503, since page icon 466 is a child of "Private" page icon
454. In the tree of Fig. 5(a), each node has zero or one "first children." Other
children of the node are indicated as "next siblings" of the first child.
Fig. 5(b) show the internal representation of page objects corresponding
to the page icons of Fig. 4 after page icon 466 is moved. Page object 502,
which corresponds to page icon 466, is a child of page object "Poles" 504
since page icon 466 has been moved to be a child of "Poles" page icon 474.
Fig. 7 shows a format of a page object 700. Each page object of Figs. 5(a) and 5(b) has this format. Fig. 7 shows only the information in the object, not the size or type of the information. Page object 700 includes an object number, an object type, an object name (e.g., "Products"), a collection number (currently unused), a number of a parent node/page, a next sibling number, a first child number, a pointer to a list of draw objects in a current layout of the
page (discussed below), a flag indicating whether the page is a stacked page, a
flag indicating whether the page is currently expanded on the display, a flag indicating whether the page is currently collapsed on the display, a flag
indicating whether the page should be published when the site is published, a
color of the page icon for the page, a status (e.g., "done," "not done"), and
user-entered comments. Fig. 8 is a flow chart showing initialization steps performed by structure
editor software 1 20 upon execution. Step 802 opens the initial window of Fig.
3. Step 804 sets default values for the site in memory 104. These default
values include a style of the layout, header, and footer, as discussed below. Step 806 creates and displays a page object for the homepage (root node) of
the site in memory 104. The created page object has a format shown in Fig. 7
and has no parent node. Step 808 stores default initial values in the root page
object.
In the described embodiment, the default name is "Home". The default class is node. The default parent number, sibling number, and first child
number is "0" . The default layout includes a banner having the default name
"Home". The stacked flag defaults to "false." The expanded flag and the publish flag default to "true." The color of the page icon defaults to a predetermined page icon color. Alternately, the each level of page icon
defaults to a different predetermined color. The status defaults to "not done".
The comments default to < null > .
Fig. 9 is a flow chart showing steps performed by structure editor software 1 20 to create a new page in the site. The steps of Fig. 9 are
performed when the user selects New Page button 314 of Fig. 3. If, in step 902, the user has previously selected a page icon (also called a "node"), then processor 102 displays a new child page icon of the selected page icon in step 904. Step 906 creates a page object in memory for the new page. If the
selected node already has an existing child (step 908) then, in step 910, the new node is made a next sibling of the existing child node. Otherwise, in step
91 2, if the selected node has no children, then the new node is made a first child of the selected node. In the described embodiment, a new page is always
a normal page. Creation of stacked pages is discussed in the copending
application. In the described embodiment, whenever a new page is created, new
draw objects are automatically created for that page. These draw objects represent links in the page layout to other nodes in the site. Currently links are created in the header and the footer of the new page to the homepage, to the
parent node, and to the "first level nodes" (i.e., to children of the homepage).
Links can also be generated for (future) children of the new page. The described embodiment automatically creates "structural links. " A draw object is created for each link. A structural link represents a link to a node having a
certain place in the site hierarchy, not a link to an absolute page. Thus, a page can contain a structural link to a sibling page. The actual identity of the sibling page is not determined when the draw object for the link is created. The identity of the link is created when the page containing the link is displayed,
previewed or published. Fig. 43 shows an example of a plurality of dialog boxes for different types of links.
Fig. 1 0 is a flow chart showing steps performed by structure editor
software 1 20 when the user selects a page icon/node (step 1002). In step
1 004, processor 102 displays the selected page icon in a predetermined color, or by drawing a line around the selected page icon, or by displaying some similar indication of selection. Processor 1 02 also sets a value in memory 104 indicating the current selected node.
Fig. 1 1 is a flow chart showing steps performed by structure editor
software 1 20 when the user moves a node. Note that, in the described embodiment, the page icon for the homepage cannot be moved. In step 1 104,
the page icon is displayed as dotted line while it is moving. In step 1 1 06, if the selected node is close to the side of another node then, in step 1 108, the node is highlighted and an arrow is displayed on the corresponding side of that node. In step 1 1 10, if the selected node is close to the bottom of another
node then, in step 1 1 1 2, the node is highlighted and an arrow is displayed on
the bottom of that node. In step 1 1 14, if the selected node has been dropped, if the dropped
node is not near another node (either side or bottom), then no action is taken.
The user cannot drop a node so that it is not a part of the site. If the selected node has been dropped near another node (either side or bottom) then, in steps
1 1 20 through 1 1 24, the page icon/node is moved to a new position in the site
hierarchy. Step 1 1 20 removes the selected node (and all its children) from its
old display position. Step 1 1 22 adds the selected page icon/node (and all its children) to its new display position. Step 1 1 24 changes one or more page objects in memory so that the page is correctly linked into its new position in
the site hierarchy. In an alternate embodiment, in step 1 1 26, the draw objects of the selected page are altered so that when the selected page is displayed by a browser, the selected page contains links to its new parents, siblings, and/or
children. The user may, of course, alter these draw objects if he so desires. The draw objects of the new parents and siblings are also changed so that a link to the moved page will be created.
Fig. 1 2 is a flow chart showing steps performed by structure editor
software 1 20 when the user changes the profile of a page. The steps of Fig.
1 2 are performed when the user selects "Profile" from a pull down-view menu to display Profile window 326 of Fig. 3. In the described embodiment, the
values in the profile window are the current values from the selected page icon/node. If the user enters a page name in step 1 206 then, in step 1 208, the name is stored in a corresponding page object having the format of Fig. 7. In
step 1 21 2, the new name is displayed in the page icon on the display. In an
alternate embodiment, the name is changed in any existing draw objects for the selected page (i.e., banners, etc.). Moreover, if other pages link to the selected page, then the name is also changed in any other draw objects of those pages.
If the page contains "smart links. " the identity of the linked-to page is not determined until the page is displayed, previewed, or published. If the user selects "publish" or "don't publish" in step 1 21 2 then, in step 1 214, the value of the publish flag is changed accordingly and, in step 1 21 6, a dot indicating "publish" is displayed in the page icon. If the user
changes the color of the selected page icon in step 1 21 8 then, in steps 1 220 and 1 222, the color value in the corresponding page object is changed accordingly and the page icon is displayed in its new color.
If the user selects "done" or "not done" in step 1 224 then, in step
1226, the done flag in the corresponding page object is changed accordingly and a checkmark indicating "done" is displayed in the page icon. If the user
has entered comments in step 1 228 then, in step 1 230, the comments in the
corresponding page object are changed accordingly.
Fig. 1 3 is a flow chart showing steps performed by structure editor
software 1 20 when the user clicks on a Site tab of a site property window.
The user can change the style and name for the site and save the creation and edit dates.
Fig. 14(a) is a flow chart showing steps performed by structure editor software 1 20 when the user clicks on a View tab of a Site property window.
The user can set the view to be either horizontal or vertical. Fig. 14(b) shows
an example of a View Tab. Fig. 20 shows a horizontal view of the site hierarchy. Fig. 21 shows a vertical view of the site hierarchy.
Fig. 1 5(a) is a flow chart showing steps performed by structure editor
software 1 20 when the user collapses a branch on the display. The user collapses a branch by selecting a page icon and selecting "Collapse" from the pull-down view menu. All nodes below the selected node are removed from the display and the selected node is displayed in a predetermined format
indicating a collapsed branch. Fig. 1 5(b) shows an example of a collapsed node. When a node is collapsed, its collapsed flag is set to "true."
Fig. 1 6 is a flow chart showing steps performed by structure editor
software 1 20 when the user expands a branch on the display. The user
expands a branch by selecting a page icon and selecting "Expand" from the pull-down view menu. The nodes below the selected node in the site hierarchy are displayed and the Collapsed indicator is removed from the selected node. When a node is expanded, its expanded flag is set to "true."
Fig. 1 9 shows an example of adding stacked data pages to the site hierarchy. When a page is a stacked page, it is displayed as overlapping pages
1 902. Stacked pages are moved at the site level of Figs. 3 and 4 in
substantially the same manner as normal pages, with the exception that a
stacked page causes multiple HTML pages to be generated. III. Page Creation and Manipulation for the Site
Fig. 22 shows an example of an initial page layout before the user has edited it. Fig. 22 is displayed after the user indicates that he wants to edit a
page by preferably: 1 ) double clicking on a page icon or 2) selecting a page
icon and selecting "Page" button 304 of Fig. 3. The display of Fig. 22 is generated by a "page editor". The described embodiment of the present invention automatically creates draw objects in memory for each page of the
site. The automatically created draw objects reflect links between pages of the
site, as described below. The display of Fig. 22 creates a page having three parts: a header
2202, a body 2204, and a footer 2206. The page editor allows individual scrolling in each of these parts. The described embodiment of the present invention automatically creates display elements of header 2202 and footer 2206. Header 2202 automatically contains a banner 2210 and a plurality of navigator buttons 221 2. In the example, the banner contains the name of the
selected page icon 456 ("Products") of Fig. 4. Navigator buttons 221 2 include buttons for home page 250 ("Home button 221 4), the Welcome page 252 ("Welcome" button 221 6), and the "Private" page ("Private" button 221 6).
Navigator buttons 221 2 preferably include an image, such as the 3D button
image shown in Fig. 22. This image may be predefined or defined by the user through use of a pop-up window.
Thus, in Fig. 22, the navigator buttons 221 2 automatically include buttons corresponding to the home page, to the first hierarchical level below the homepage, and to the parent page. Alternate implementations of the present invention automatically display navigator buttons for one or more of the home page, the parent page, sibling pages, the first level, children pages, and any other appropriate pages. In some embodiments, the user chooses which
navigator buttons are generated automatically by way of a pop-up site window. Footer 2206 automatically contains a plurality of text buttons 2230.
These text buttons preferably correspond to the navigator buttons 221 2.
Thus, text buttons 2230 include buttons for home page 250 ("Home text
button 2230), the Welcome page 452 ("Welcome" text button 2232), and the "Private" page 454 ("Private" text button 2234). The internal memory representation of banner 221 0 and of buttons 221 2 and 2230 are discussed in
detail below.
Fig. 22 also shows a "Properties" window 2250 in which a "View" tab is selected. Properties window 2250 includes three tabs: a "View" tab 2252, a "Page" tab 2254, and a "Layout" tab 2256. Properties window 2250
currently shows view properties because View tab 2252 is selected.
Properties window 2250 includes a "Measurement Unit" area 2260, a "Element border" area 2262, "Grid Width" and "Grid Height" areas" 2264, 2266, a "Show Grid" flag 2265, font size areas 2268, 2272, a "Color" area
2272, a "Horizontal Splitter" flag area 2270, and a "Snap to Grid" flag area
2276.
When the page editor is started, the values of Properties window 326 are properties for the displayed page. Thus, in the example, the grid is
measured in unit of pixels. Element borders around each display element are displayed. A grid of 24 x 24 pixels is displayed. The specified fonts are used.
The page uses the colors described in the colors area 2272. Horizontal
splitters 2280, 2282 are displayed. The "Snap to Grid" property is turned off. It will be understood by persons of ordinary skill in the art that structure editor software 1 20 stores values corresponding to this Property window and each
Property window discussed herein in memory 104.
Fig. 24 is an example showing an internal memory representation of draw objects automatically generated by structure editor software 1 20. The draw objects are generated when a page layout is modified. The internal
representation includes a list of objects (a layout object), representing the header, body, and footer of the page of Fig. 22. Thus, the list of draw objects includes a banner draw object 2402 (corresponding to banner 2210), a
navigator buttons draw object 2404 (corresponding to navigator buttons 221 2), and text buttons draw object 2406 (corresponding to text buttons
221 4). In the described embodiment, all draw objects of the header 2202 are stored together in a layout object and a pointer points to the beginning of this list. Similarly, all objects of the footer 2206 are stored together in a layout
object and a pointer points to the beginning of this list. In the described embodiment, the user has not entered any elements into the body 2204 and a pointer to body elements points to a null list.
Fig. 25 is an example of a draw object for a page banner. It includes a
bitmap of the banner and the name of the page (e.g., "Products"). Fig. 26(a) is
an example of a draw object for a navigator button. Fig. 26(a) includes a node
number to which it will link when displayed by a browser, a name of the linked to page, and an image of the navigator button (e.g., a GIF image). Fig. 26(a) includes a smart link to another node, which is specified by relationship, and an image. The identity of the link is determined when the page is displayed,
previewed, or published. Fig. 27 is an example of a draw object for a text object. It includes a node number to which it will link when displayed by a browser, a name of the linked to page, and a string displayed in the text
button. In the described embodiment, each draw object contains its type, its X
position, Y position, width, and height. An example of a draw object of text and a draw image for an image is shown elsewhere in this document. It will be understood that each type of display element in a page (e.g., text, image,
button, etc.) has a corresponding type of draw object.
Fig. 23 is a flow chart showing steps performed by structure editor software 1 20 to display the page layout of Fig. 22 during execution of the page editor. In step 2302, the page editor determines whether this is the first
time that the page has been edited. If it is not the first time, in step 2304, the
current page layout is displayed in accordance with the draw objects for the page. The page layout will include the automatically generated banner, navigator buttons, and text buttons, unless the user has previously deleted
them.
If it is the first time, in step 2306, the editor displays the default page layout in accordance with the draw objects for the page. The page layout will include the automatically generated banner, navigator buttons, and text
buttons. Step 2308 allow the user to modify the page layout using drag and
drop methods. It will be understood that the user does not have to modify the page at all if he doesn't want to. The automatically generated page elements
will still be a part of the page. The user exits the page editor by, e.g., clicking on Site button 302, Style button 206, Assets button 308, or publish button 310. After the user has edited a page, he can still move the page around in the site hierarchy by using the structure editor.
IV. HTML Generation for the Site
Once the user has created a hierarchy of pages for the site as described
above, the user needs to be able to generate HTML for all pages of the site.
Fig. 28 shows an example of a display used to allow the user to publish the pages of a site. Fig. 28 shows a screen displayed when the user clicks on
"Publish" button 310 of Fig. 3. The screen includes three buttons "Settings"
2802, "Stage" 2804, and "Publish" 2806. Once the display of Fig. 28 is displayed, the user can either "stage" or "publish" his site. Generally, staging is performed first and publishing is performed once the site is debugged. Staging and publishing are substantially the same, differing in when they are performed during the site development process. The user can also set configuration parameters to control the publishing or staging process. Clicking
on either "publish" button 2802 or "Stage" button 2804 causes the described
embodiment to generate HTML code for each page in the site (or only for pages indicated by the publish flag or by the user). This process is described below.
Clicking on "Settings" button 2802 causes a pop-up window 2808 to be displayed. Clicking on "Stage" tab 281 0 or "Publish" tab 281 2 will display
a window, which allows the user to specify a storage location for the staged or published site. Clicking on a "Modify" tab 2814 causes the pop-up window
2902 of Fig. 29 to be displayed. Window 2902 allows the user to indicate
certain attributes of the HTML to be generated for the site (e.g., text only, black and white (grey scale), or low-resolution).
Fig. 30 is a flow chart showing steps performed by structure editor
software 1 20 to publish all the pages of a site. It will be understood that the
steps of Fig. 30 are performed by processor 1 02 executing instructions in structure editor software 1 20. In Fig. 30, steps 3002 through 301 0 form a loop repeated for each page in the site, i.e., for each page object stored in the
memory. In the described embodiment, the tree of page objects is traversed in
a recursive, depth first manner in a manner known to persons of ordinary skill in the art. For each page object, in step 3004, if the stacked flag of the current page object indicates that the current page is a stacked page, then
processor 102 creates HTML for a plurality of pages. If the current page object
is not a stacked page then, in step 3008, processor 1 02 builds HTML for a "normal" page. In either case, the HTML for the page is then written to a storage medium of the system.
It will be understood that, generally, each page object has a
corresponding list of draw objects describing the elements of the page for the header, body and footer of the page, and that processor 102 generates HTML in accordance with the draw objects. As described above, each list of draw
objects automatically includes draw objects representing automatically
generated banners and links (e.g., to the home, first level, parent, sibling, and/or children pages of that page). The draw objects of a page may also represent other, additional links added by the user that are not a part of the site hierarchy. Moreover, the user can use the page editor to remove some of the automatically generated draw objects links if he so desires. Unless the user
explicitly removes them, however, these automatically generated links are
present in each page layout. Thus, the generated HTML for each page will contain links to the home, parents, siblings, and/or children pages for each
page of the site view.
V. HTML Generation for a Page
Fig. 31 is a flow chart showing steps performed by the structure editor software to publish a normal page. Fig. 32 is a flow chart showing steps performed by the structure editor software to publish a stacked page. The steps of Figs. 31 and 32 are similar, except that the steps of Fig. 32 generates multiple HTML pages for the stacked page. Step 31 10 creates initial HTML for
the page as shown in Fig. 33. This step creates the beginning of an HTML
page. Steps 31 04-3108 create HTML tables for each of the header, body, and
footer as shown in Figs. 34 and 35. Step 31 10 creates final HTML for the end of the page as shown in Fig. 36. The preferred embodiment generates
Netscape HTML versions 3.X.
Fig. 32 shows the creation of a plurality of HTML pages for a stacked page. Each HTML contains, for example, data for one record of a database associated with the stacked page. Each of the plurality of HTML pages has a
common format including the same fields of the database and the same layout
of the fields. Each page of the plurality of pages has the same format, but different data.
Step 3314 of Fig. 33 shows that the HTML for a page includes a tag specifying the colors that a browser will use to display regular, visited, and active links. Other embodiments specify other HTML tags that specify other attributes common to the page.
Fig. 34 is a flow chart showing steps to build an HTML table. In the described embodiment, an HTML table is generated for the header, body, and footer of each page. Steps 3402-3408 generate a matrix in memory 104 as discussed below in connection with Figs. 37-40. Step 3410 create the HTML
table in accordance with the matrix as shown in Fig. 35. Fig. 35 shows steps that create an HTML table. Step 3502 writes a table tag including a border of zero width and cellpadding and cellspacing of
zero. Step 3504 generates a table header including column and width
definitions for the HTML table. Steps 3506-351 8 go through each row and column of the matrix to generate a plurality of cells in the HTML table. Some of the cells in the HTML table can be several columns wide and/or several rows
high. Step 3520 generates an end of table tag.
Fig. 37 is an example of first steps involved in determining an HTML table size for a layout element of a header, body, or footer. In the example, the
layout element has four display elements. Each display element corresponds to
one draw object of the page. As discussed above, each draw object has an X
position (a start row) and a length. Each draw object also has a Y position (a
start column) and a height. For each object, a first column edge is the X start position and a second column edge is the X start position plus the length. In addition, for each object, a first row edge is the Y start position and a second row edge is the Y start position plus the height. Processor 102 finds the row
edges and columns edges for a current page, yielding data 3702 and 3704.
Fig. 37 is an example of second steps involved in determining an HTML table size for a layout element. Once the column and row edges of the draw
objects are determined, the edges are sorted, duplicate edges are removed from
the sorted list, yielding unique row edges and unique column edges (steps 3404 and 3406 of Fig. 34). The unique rows edges and column edges are then counted. In the example, the objects have six column edges and seven row edges. Once the unique row edges and column edges are determined, the
column widths and row heights for each column and row are determined.
Fig. 39 is an example of a matrix 3802 generated in accordance with the edges and draw objects. Matrix 3902 has a number of rows equal to the number of row edges plus one. The matrix has a number of columns equal to
the number of column edges plus one. Thus, in the example, the matrix has seven columns and eight rows. Each element 3904 of the matrix has a pointer field and an occupied flag. The element of row 7, column 2 of the matrix
points to object number 1 and is marked as occupied. The next four elements in row 2 are also marked as occupied. The element of row 3, column 3 points to object number 2 and is marked as occupied. The element of row 2, column 5 points to object number 3 and is marked as occupied. The next four
elements in column 5 are also marked as occupied. The element of row 5,
column 3 points to object number 4 and is marked as occupied.
Fig. 40 is a block diagram of how the matrix 3902 is used to generate an HTML table. The HTML table is used by a browser to display a portion of a page on display device 1 60 (such as a header, body, or a footer, (an alternate
embodiment of the present invention creates a single table for each page of the site). Each element of the matrix is used to generate a cell in an HTML table (although some cells occupy more than one row or more than one column) . For
example, the matrix element in row 1 , column 1 causes an empty table cell to
be generated. Each row in the HTML table has a height in pixels that is equal to the height for that matrix row. Each cell in the HTML table has a width that
is equal to the width of the matrix for that column.
As is known to persons of ordinary skill in the art, the cells in the table
can be of varying sizes (i.e., can use the HTML tags "ROWSPAN" and
COLSPAN"). The matrix element in row 2, column 5 causes generates of a cell that spans four rows (ROWSPAN = 4). The matrix element in row 7, column 2
causes generation of a cell that spans five column (COLSPAN = 5).
Fig. 41 shows an example of a Style display. The display of Fig. 41 is shown when the user selects Style button 306. The Style button display allows the user to select an overall default appearance of all pages in the site.
The user can override the style for a given page by defining a different style for
the page (not shown). In the described embodiment, the values shown in Fig. 41 are stored in locations of memory 104. The automatic generation of banners, navigation buttons, and text buttons is performed in accordance with user-specified style values.
Fig. 42 shows an example of an Assets Display. The Assets display shows the files, links, and objects in the data processing system. For example, the assets shown in Fig. 42 are the draw objects for the "Products" page of
Fig. 22.
Fig. 43 shows an example of a plurality of link dialog boxes, showing a
structural link, an internal link, and an external link.
Fig. 44 is a flow chart showing identification of structural links for a page. The links preferably are identified when the page is displayed, previewed or published. Internal and external links are "absolute" links. Structural links
are identified only as "next sibling link," "next child link", etc. For each link, the node-that-is-linked-to is identified by looking at the page hierarchy specified by the page layout tree. After the node is identified, the processor finds the URL, name, etc of the node and generates the display or HTML for the
structural link.
In summary, the described embodiment of the present invention allows a user to define a hierarchy of pages for a Web Site. A structure editor in
accordance with the present invention automatically creates page objects for
each site that reflects the user-defined site hierarchy. Each page has an associated plurality of draw objects that define the display elements of the page. When the user "publishes" a page, the described embodiment generates
HTML code for each page. Thus, even if the user never edits a page, and only
creates a site hierarchy, each page will have an automatically created banner and automatically created links to other pages of the site. The links can be structural links (smart links), internal links, or external links. Moreover, the
pages of the site conform to a user-specified style.
Other embodiments will be apparent to those skilled in the art from consideration of the specification and practice of the invention disclosed herein.
It is intended that the specification and examples be considered as exemplary only, with a true scope of the invention being indicated by the following claims and equivalents.
