NoteCards was a hypertext -based personal knowledge base system developed at Xerox PARC by Randall Trigg, Frank Halasz and Thomas Moran in 1984. NoteCards was developed after Trigg's pioneering 1983 Ph.D. thesis on hypertext while at the University of Maryland College Park .

65-746: NoteCards was built to model four basic kinds of objects: notecards, links , browser card, and a filebox. Each window is an analog of a cue card; window sizes may vary, but contents cannot scroll. Local and global maps are available through browsers. There are over 40 different nodes which support various media. The basic construct in NoteCards is a semantic network composed of notecards connected by typed links. Each notecard contains an arbitrary amount of information embodied in text, graphics, images, or some other editable substance. Links are used to represent binary connections between cards. NoteCards provides two specialized types of cards, Browsers and FileBoxes, that help

130-538: A "one-to-many" link, an "extended link" or a "multi-tailed link") is a hyperlink which leads to multiple endpoints; the link is a set-valued function . Tim Berners-Lee saw the possibility of using hyperlinks to link any information to any other information over the Internet . Hyperlinks were therefore integral to the creation of the World Wide Web . Web pages are written in the hypertext mark-up language HTML . This

195-411: A "trail" of related information, and then scroll back and forth among pages in a trail as if they were on a single microfilm reel. In a series of books and articles published from 1964 through 1980, Nelson transposed Bush's concept of automated cross-referencing into the computer context, made it applicable to specific text strings rather than whole pages, generalized it from a local desk-sized machine to

260-502: A DTP program. However, many web designers still prefer to write HTML without the assistance of a WYSIWYG editor, for greater control and ability to fine-tune the appearance and functionality. Another reason that some Web designers write in HTML is that WYSIWYG editors often result in excessive lines of code, leading to code bloat that can make the pages hard to troubleshoot . Desktop publishing produces primarily static print or digital media ,

325-436: A Typewriter , and it had to actually explain how a Mac could do so much more than a typewriter. The ability to create WYSIWYG page layouts on screen and then print pages containing text and graphical elements at 300 dpi resolution was a major development for the personal computer industry. The ability to do all this with industry standards like PostScript also radically changed the traditional publishing industry, which at

390-426: A bad reputation as a result of untrained users who created poorly organized, unprofessional-looking " ransom note effect " layouts. (Similar criticism was leveled again against early World Wide Web publishers a decade later.) However, some desktop publishers who mastered the programs were able to achieve near professional results. Desktop publishing skills were considered of primary importance in career advancement in

455-507: A document, e.g. a webpage , or other resource, or to a position in a webpage. The latter is achieved by means of an HTML element with a "name" or "id" attribute at that position of the HTML document. The URL of the position is the URL of the webpage with a fragment identifier  – "# id attribute " – appended. When linking to PDF documents from an HTML page the " id attribute " can be replaced with syntax that references

520-431: A graphical user interface, the appearance of a mouse cursor may change into a hand motif to indicate a link. In most graphical web browsers, links are displayed in underlined blue text when they have not been visited, but underlined purple text when they have. When the user activates the link (e.g., by clicking on it with the mouse ) the browser displays the link's target. If the target is not an HTML file, depending on

585-562: A hyperlink is known as its source document. For example, in content from Misplaced Pages or Google Search , many words and terms in the text are hyperlinked to definitions of those terms. Hyperlinks are often used to implement reference mechanisms such as tables of contents, footnotes , bibliographies , indexes , and glossaries . In some hypertext, hyperlinks can be bidirectional: they can be followed in two directions, so both ends act as anchors and as targets. More complex arrangements exist, such as many-to-many links. The effect of following

650-421: A hyperlink may vary with the hypertext system and may sometimes depend on the link itself; for instance, on the World Wide Web most hyperlinks cause the target document to replace the document being displayed, but some are marked to cause the target document to open in a new window (or, perhaps, in a new tab ). Another possibility is transclusion , for which the link target is a document fragment that replaces

715-474: A local printer, then print the same file at DTP service bureaus using optical resolution 600+ ppi PostScript printers such as those from Linotronic . Later, the Macintosh II was released, which was considerably more suitable for desktop publishing due to its greater expandability, support for large color multi-monitor displays, and its SCSI storage interface (which allowed hard drives to be attached to

780-407: A new window to be created. It is especially common to see this type of link when one large website links to an external page. The intention in that case is to ensure that the person browsing is aware that there is no endorsement of the site being linked to by the site that was linked from. However, the attribute is sometimes overused and can sometimes cause many windows to be created even while browsing

845-528: A page number or another element of the PDF, for example, "# page=386 ". A web browser usually displays a hyperlink in some distinguishing way, e.g. in a different color , font or style , or with certain symbols following to visualize link target or document types. This is also called link decoration . The behavior and style of links can be specified using the Cascading Style Sheets (CSS) language. In

910-426: A parameter designating the way text flows around the object (also known as "wraparound" or "runaround"). As desktop publishing software still provides extensive features necessary for print publishing, modern word processors now have publishing capabilities beyond those of many older DTP applications, blurring the line between word processing and desktop publishing. In the early 1980s, the graphical user interface

975-446: A printable area if bleed printing is not possible as is the case with most desktop printers . A web page is an example of a digital page that is not constrained by virtual paper parameters. Most digital pages may be dynamically re-sized, causing either the content to scale in size with the page or the content to re-flow . Master pages are templates used to automatically copy or link elements and graphic design styles to some or all

1040-473: A regular window , but in a special hover box , which disappears when the cursor is moved away (sometimes it disappears anyway after a few seconds, and reappears when the cursor is moved away and back). Mozilla Firefox , IE , Opera , and many other web browsers all show the URL. In addition, the URL is commonly shown in the status bar . Normally, a link opens in the current frame or window, but sites that use frames and multiple windows for navigation can add

1105-550: A single document (1966), and soon after for connecting between paragraphs within separate documents (1968), with NLS . Ben Shneiderman working with graduate student Dan Ostroff designed and implemented the highlighted link in the HyperTIES system in 1983. HyperTIES was used to produce the world's first electronic journal, the July 1988 Communications of the ACM , which was cited as the source for

1170-538: A single site. Another special page name is "_top", which causes any frames in the current window to be cleared away so that browsing can continue in the full window. The term "link" was coined in 1965 (or possibly 1964) by Ted Nelson at the start of Project Xanadu . Nelson had been inspired by " As We May Think ", a popular 1945 essay by Vannevar Bush . In the essay, Bush described a microfilm-based machine (the Memex ) in which one could link any two pages of information into

1235-471: A software which separates itself from the TeX world and develops itself in the direction of WYSIWYG markup-based typesetting is GNU TeXmacs . On a different note, there is a slight overlap between desktop publishing and what is known as hypermedia publishing (e.g. web design , kiosk, CD-ROM ). Many graphical HTML editors such as Microsoft FrontPage and Adobe Dreamweaver use a layout engine similar to that of

1300-462: A special "target" attribute to specify where the link loads. If no window exists with that name, a new window is created with the ID, which can be used to refer to the window later in the browsing session. Creation of new windows is probably the most common use of the "target" attribute. To prevent accidental reuse of a window, the special window names "_blank" and "_new" are usually available, and always cause

1365-497: A summary of the current status of US copyright law as to hyperlinking, see the discussion regarding the Arriba Soft and Perfect 10 cases . Somewhat controversially, Vuestar Technologies has tried to enforce patents applied for by its owner, Ronald Neville Langford, around the world relating to search techniques using hyperlinked images to other websites or web pages.

1430-424: A theoretical proprietary worldwide computer network, and advocated the creation of such a network. Though Nelson's Xanadu Corporation was eventually funded by Autodesk in the 1980s, it never created this proprietary public-access network. Meanwhile, working independently, a team led by Douglas Engelbart (with Jeff Rulifson as chief programmer ) was the first to implement the hyperlink concept for scrolling within

1495-437: A typical web browser, this would display as the underlined word "Example" in blue, which when clicked would take the user to the example.com website. This contributes to a clean, easy to read text or document. By default, browsers will usually display hyperlinks as such: When the cursor hovers over a link, depending on the browser and graphical user interface, some informative text about the link can be shown, popping up, not in

1560-414: A whole document or to a specific element within a document. Hypertext is text with hyperlinks. The text that is linked from is known as anchor text . A software system that is used for viewing and creating hypertext is a hypertext system , and to create a hyperlink is to hyperlink (or simply to link ). A user following hyperlinks is said to navigate or browse the hypertext. The document containing

1625-576: A wide variety of content, from menus to magazines to books, without the expense of commercial printing. Desktop publishing often requires the use of a personal computer and WYSIWYG page layout software to create documents for either large-scale publishing or small-scale local printing and distribution – although non-WYSIWYG systems such as TeX and LaTeX are also used, especially in scientific publishing . Originally, desktop publishing methods provided more control over design, layout, and typography than word processing software but

1690-576: Is a distinction between the mere act of linking to someone else's website, and linking to content that is illegal (e.g., gambling illegal in the US) or infringing (e.g., illegal MP3 copies). Several courts have found that merely linking to someone else's website, even if by bypassing commercial advertising, is not copyright or trademark infringement, regardless of how much someone else might object. Linking to illegal or infringing content can be sufficiently problematic to give rise to legal liability. Compare for

1755-613: Is added. In certain jurisdictions , it is or has been held that hyperlinks are not merely references or citations , but are devices for copying web pages. In the Netherlands, Karin Spaink was initially convicted in this way of copyright infringement by linking, although this ruling was overturned in 2003. The courts that advocate this view see the mere publication of a hyperlink that connects to illegal material to be an illegal act in itself, regardless of whether referencing illegal material

1820-459: Is illegal. In 2004, Josephine Ho was acquitted of 'hyperlinks that corrupt traditional values' in Taiwan . In 2000, British Telecom sued Prodigy , claiming that Prodigy infringed its patent ( U.S. patent 4,873,662 ) on web hyperlinks. After litigation , a court found for Prodigy, ruling that British Telecom 's patent did not cover web hyperlinks. In United States jurisprudence , there

1885-423: Is important. In the 2010s, interactive front-end components of TeX, such as TeXworks and LyX , have produced "what you see is what you mean" ( WYSIWYM ) hybrids of DTP and batch processing. These hybrids are focused more on the semantics than the traditional DTP. Furthermore, with the advent of TeX editors the line between desktop publishing and markup-based typesetting is becoming increasingly narrow as well;

1950-443: Is not allowed without permission. Contentious in particular are deep links , which do not point to a site's home page or other entry point designated by the site owner, but to content elsewhere, allowing the user to bypass the site's own designated flow, and inline links , which incorporate the content in question into the pages of the linking site, making it seem part of the linking site's own content unless an explicit attribution

2015-590: Is that DTP software is generally interactive and "What you see [onscreen] is what you get" ( WYSIWYG ) in design, while other digital typesetting software, such as TeX, LaTeX and other variants, tend to operate in " batch mode ", requiring the user to enter the processing program's markup language (e.g. HTML ) without immediate visualization of the finished product. This kind of workflow is less user-friendly than WYSIWYG, but more suitable for conference proceedings and scholarly articles as well as corporate newsletters or other applications where consistent, automated layout

2080-488: Is the creation of documents using dedicated software on a personal ("desktop") computer . It was first used almost exclusively for print publications, but now it also assists in the creation of various forms of online content. Desktop publishing software can generate page layouts and produce text and image content comparable to the simpler forms of traditional typography and printing . This technology allows individuals, businesses, and other organizations to self-publish

2145-738: Is what a hyperlink to the home page of the W3C organization could look like in HTML code: This HTML code consists of several tags : Webgraph is a graph , formed from web pages as vertices and hyperlinks, as directed edges. The W3C recommendation called XLink describes hyperlinks that offer a far greater degree of functionality than those offered in HTML. These extended links can be multidirectional , remove linking from, within, and between XML documents. It can also describe simple links , which are unidirectional and therefore offer no more functionality than hyperlinks in HTML. Permalinks are URLs that are intended to remain unchanged for many years into

2210-505: Is why a link to a fragment is called an anchor link (that is, a link to an anchor). For example, in XML , the element <anchor id="name" />" provides anchoring capability (as long as the DTD or schema defines it), and in wiki markup , {{anchor|name}} is a typical example of implementing it. In word processor apps, anchors can be inserted where desired and may be called bookmarks . In URLs ,

2275-505: The file type and on the browser and its plugins , another program may be activated to open the file. The HTML code contains some or all of the five main characteristics of a link: It uses the HTML element "a" with the attribute "href" (HREF is an abbreviation for "Hypertext REFerence" ) and optionally also the attributes "title", "target", and " class " or "id": To embed a link into a web page, blogpost, or comment, it may take this form: In

2340-663: The 1980s, but increased accessibility to more user-friendly DTP software has made DTP a secondary skill to art direction , graphic design , multimedia development, marketing communications , and administrative careers . DTP skill levels range from what may be learned in a couple of hours (e.g., learning how to put clip art in a word processor), to what's typically required in a college education. The discipline of DTP skills range from technical skills such as prepress production and programming, to creative skills such as communication design and graphic image development . As of 2014 , Apple computers remain dominant in publishing, even as

2405-458: The 2010s, vendors have sought to provide users with a single application that can meet almost all their publication needs. In earlier modern-day usage, DTP usually did not include digital tools such as TeX or troff , though both can easily be used on a modern desktop system, and are standard with many Unix-like operating systems and are readily available for other systems. The key difference between digital typesetting software and DTP software

2470-437: The composition and editing of purely textual documents. Word did not begin to acquire desktop publishing features until a decade later, and by 2003, it was regarded only as "good" and not "great" at desktop publishing tasks. The term "desktop publishing" is attributed to Aldus founder Paul Brainerd , who sought a marketing catchphrase to describe the small size and relative affordability of this suite of products, in contrast to

2535-735: The creation of manuals and other long-format documents. Desktop publishing moved into the home market in 1986 with Professional Page for the Amiga , Publishing Partner (now PageStream) for the Atari ST , GST's Timeworks Publisher on the PC and Atari ST, and Calamus for the Atari TT030 . Software was published even for 8-bit computers like the Apple II and Commodore 64 : Home Publisher, The Newsroom, and geoPublish . During its early years, desktop publishing acquired

2600-487: The entire NoteCards work environment. NoteCards was available commercially from the Common Lisp software vendor Venue, compiled for Solaris 2.5 and 7 (untested on later versions) and Linux x86 with the X Window System . Hyperlink In computing , a hyperlink , or simply a link , is a digital reference to data that the user can follow or be guided to by clicking or tapping . A hyperlink points to

2665-401: The expensive commercial phototypesetting equipment of the day. Before the advent of desktop publishing, the only option available to most people for producing typed documents (as opposed to handwritten documents) was a typewriter , which offered only a handful of typefaces (usually fixed-width) and one or two font sizes. Indeed, one popular desktop publishing book was titled The Mac is Not

2730-439: The focus of this article. Similar skills, processes, and terminology are used in web design . Digital typography is the specialization of typography for desktop publishing. Web typography addresses typography and the use of fonts on the World Wide Web . Desktop style sheets apply formatting for print, Web Cascading Style Sheets (CSS) provide format control for web display. Web HTML font families map website font usage to

2795-485: The full linked content is not needed, as is the case when rearranging a page layout . An anchor hyperlink (anchor link) is a link bound to a portion of a document, which is often called a fragment . The fragment is generally a portion of text or a heading, though not necessarily. For instance, it may also be a hot area in an image ( image map in HTML ), a designated, often irregular part of an image. Fragments are marked with anchors (in any of various ways), which

2860-613: The future, yielding hyperlinks that are less susceptible to link rot . Permalinks are often rendered simply, that is, as friendly URLs, so as to be easy for people to type and remember. Permalinks are used in order to point and redirect readers to the same Web page , blog post or any online digital media. The scientific literature is a place where link persistence is crucial to the public knowledge. A 2013 study in BMC Bioinformatics analyzed 15,000 links in abstracts from Thomson Reuters' Web of Science citation index, founding that

2925-438: The hash character (#) precedes the name of the anchor for the fragment. One way to define a hot area in an image is by a list of coordinates that indicate its boundaries. For example, a political map of Africa may have each country hyperlinked to further information about that country. A separate invisible hot area interface allows for swapping skins or labels within the linked hot areas without repetitive embedding of links in

2990-592: The inability to control letter spacing , kerning , and other typographic features , and the discrepancies between screen display and printed output. However, it was an unheard-of combination at the time, and was received with considerable acclaim. Behind the scenes, technologies developed by Adobe Systems set the foundation for professional desktop publishing applications. The LaserWriter and LaserWriter Plus printers included scalable Adobe PostScript fonts built into their ROM memory. The LaserWriter's PostScript capability allowed publication designers to proof files on

3055-657: The introduction of TeX , and was extended in 1985 with the introduction of LaTeX . The desktop publishing market took off in 1985 with the introduction in January of the Apple LaserWriter laser printer for the year-old Apple Macintosh personal computer. This momentum was kept up with the release that July of PageMaker software from Aldus , which rapidly became the standard software application for desktop publishing. With its advanced layout features, PageMaker immediately relegated word processors like Microsoft Word to

3120-455: The latter has evolved to include most, if not all, capabilities previously available only with dedicated desktop publishing software. The same DTP skills and software used for common paper and book publishing are sometimes used to create graphics for point of sale displays , presentations , infographics , brochures , business cards , promotional items , trade show exhibits , retail package designs and outdoor signs . Desktop publishing

3185-517: The layout, placed, or – with database publishing applications – linked to an external source of text which allows multiple editors to develop a document at the same time. Graphic design styles such as color, transparency and filters may also be applied to layout elements. Typography styles may be applied to text automatically with style sheets . Some layout programs include style sheets for images in addition to text. Graphic styles for images may include border shapes, colors, transparency, filters, and

3250-456: The link anchor within the source document. Not only persons browsing the document may follow hyperlinks. These hyperlinks may also be followed automatically by programs. A program that traverses the hypertext, following each hyperlink and gathering all the retrieved documents is known as a Web spider or crawler . An inline link displays remote content without the need for embedding the content. The remote content may be accessed with or without

3315-569: The link concept in Tim Berners-Lee 's Spring 1989 manifesto for the Web. In 1988, Ben Shneiderman and Greg Kearsley used HyperTIES to publish "Hypertext Hands-On!", the world's first electronic book. Released in 1987 for the Apple Macintosh , the database program HyperCard allowed for hyperlinking between various pages within a document, as well as to other documents and separate applications on

3380-412: The median lifespan of Web pages was 9.3 years, and just 62% were archived. The median lifespan of a Web page constitutes high-degree variable, but its order of magnitude usually is of some months. A link from one domain to another is said to be outbound from its source anchor and inbound to its target. The most common destination anchor is a URL used in the World Wide Web . This can refer to

3445-773: The most popular software has changed from QuarkXPress – an estimated 95% market share in the 1990s – to Adobe InDesign . An Ars Technica writer said in an article: "I've heard about Windows-based publishing environments, but I've never actually seen one in my 20+ years in design and publishing". There are two types of pages in desktop publishing: digital pages and virtual paper pages to be printed on physical paper pages . All computerized documents are technically digital, which are limited in size only by computer memory or computer data storage space. Virtual paper pages will ultimately be printed , and will therefore require paper parameters coinciding with standard physical paper sizes such as A4, letterpaper and legalpaper. Alternatively,

3510-401: The pages of a multipage document. Linked elements can be modified without having to change each instance of an element on pages that use the same element. Master pages can also be used to apply graphic design styles to automatic page numbering. Cascading Style Sheets can provide the same global formatting functions for web pages that master pages provide for virtual paper pages. Page layout is

3575-463: The process by which the elements are laid on the page orderly, aesthetically and precisely. The main types of components to be laid out on a page include text , linked images (that can only be modified as an external source), and embedded images (that may be modified with the layout application software). Some embedded images are rendered in the application software, while others can be placed from an external source image file. Text may be keyed into

3640-479: The same computer. In 1990, Windows Help , which was introduced with Microsoft Windows 3.0 , had widespread use of hyperlinks to link different pages in a single help file together; in addition, it had a visually different kind of hyperlink that caused a popup help message to appear when clicked, usually to give definitions of terms introduced on the help page. The first widely used open protocol that included hyperlinks from any Internet site to any other Internet site

3705-489: The system). Macintosh-based systems continued to dominate the market into 1986, when the GEM -based Ventura Publisher was introduced for MS-DOS computers. PageMaker's pasteboard metaphor closely simulated the process of creating layouts manually, but Ventura Publisher automated the layout process through its use of tags and style sheets and automatically generated indices and other body matter. This made it particularly suitable for

3770-603: The time was accustomed to buying end-to-end turnkey solutions for digital typesetting which came with their own proprietary hardware workstations. Newspapers and other print publications began to transition to DTP-based programs from older layout systems such as Atex and other programs in the early 1980s. Desktop publishing was still in its early stage in the early 1980s. Users of the PageMaker/LaserWriter/Macintosh 512K system endured frequent software crashes, Mac's low-resolution 512x342 1-bit monochrome screen,

3835-449: The user following the link. An inline link may display a modified version of the content; for instance, instead of an image, a thumbnail , low resolution preview , cropped section, or magnified section may be shown. The full content is then usually available on demand, as is the case with print publishing software – e.g., with an external link . This allows for smaller file sizes and quicker response to changes when

3900-455: The user to manage networks of cards and links. NoteCards was implemented in LISP on D-machine workstations from Xerox which used large, high-resolution displays . The NoteCards interface is event-driven. One interesting feature of NoteCards is that authors may use LISP commands to customize or create entirely new node types. The powerful programming language allows almost complete customization of

3965-497: The various skin elements. Text hyperlink. Hyperlink is embedded into a word or a phrase and makes this text clickable. Image hyperlink. Hyperlink is embedded into an image and makes this image clickable. Bookmark hyperlink. Hyperlink is embedded into a text or an image and takes visitors to another part of a web page. E-mail hyperlink. Hyperlink is embedded into e-mail address and allows visitors to send an e-mail message to this e-mail address. A fat link (also known as

4030-457: The virtual paper page may require a custom size for later trimming. Some desktop publishing programs allow custom sizes designated for large format printing used in posters , billboards and trade show displays . A virtual page for printing has a predesignated size of virtual printing material and can be viewed on a monitor in WYSIWYG format. Each page for printing has trim sizes (edge of paper) and

4095-494: Was first developed at Xerox PARC in the 1970s. A contradictory claim states that desktop publishing began in 1983 with a program developed by James Davise at a community newspaper in Philadelphia. The program Type Processor One ran on a PC using a graphics card for a WYSIWYG display and was offered commercially by Best Info in 1984. Desktop typesetting with only limited page makeup facilities arrived in 1978–1979 with

4160-560: Was still in its embryonic stage and DTP software was in a class of its own when compared to the leading word processing applications of the time. Programs such as WordPerfect and WordStar were still mainly text-based and offered little in the way of page layout, other than perhaps margins and line spacing. On the other hand, word processing software was necessary for features like indexing and spell checking – features that are common in many applications today. As computers and operating systems became more powerful, versatile, and user-friendly in

4225-573: Was the Gopher protocol from 1991. It was soon eclipsed by HTML after the 1993 release of the Mosaic browser (which could handle Gopher links as well as HTML links). HTML's advantage was the ability to mix graphics, text, and hyperlinks, unlike Gopher, which just had menu-structured text and hyperlinks. While hyperlinking among webpages is an intrinsic feature of the web , some websites object to being linked by other websites; some have claimed that linking to them
