Hypertext is text displayed on a computer display or other electronic devices with references ( hyperlinks ) to other text that the reader can immediately access. Hypertext documents are interconnected by hyperlinks , which are typically activated by a mouse click, keypress set, or screen touch. Apart from text, the term "hypertext" is also sometimes used to describe tables, images, and other presentational content formats with integrated hyperlinks. Hypertext is one of the key underlying concepts of the World Wide Web , where Web pages are often written in the Hypertext Markup Language (HTML). As implemented on the Web, hypertext enables the easy-to-use publication of information over the Internet .

83-458: The WikiWikiWeb is the first wiki , or user-editable website. It was launched on 25 March 1995 by programmer Ward Cunningham and it has been a read-only archive since 2015. The name WikiWikiWeb originally also applied to the wiki software that operated the website, which was later renamed to "WikiBase". WikiWikiWeb is the first wiki , or user-editable website. The site was launched on 25 March 1995 by programmer Ward Cunningham to accompany

166-481: A Memex . A Memex would hypothetically store — and record — content on reels of microfilm, using electric photocells to read coded symbols recorded next to individual microfilm frames while the reels spun at high speed, and stopping on command. The coded symbols would enable the Memex to index, search, and link content to create and follow associative trails. Because the Memex was never implemented and could only link content in

249-558: A taxonomy , or other forms of ad hoc content organization. Wiki implementations can provide one or more ways to categorize or tag pages to support the maintenance of such index pages, such as a backlink feature which displays all pages that link to a given page. Adding categories or tags to a page makes it easier for other users to find it. Most wikis allow the titles of pages to be searched amongst, and some offer full text search of all stored content. Some wiki communities have established navigational networks between each other using

332-601: A wiki but without hypertext punctuation, which was not invented until 1987. The early 1980s also saw a number of experimental "hyperediting" functions in word processors and hypermedia programs, many of whose features and terminology were later analogous to the World Wide Web . Guide , the first significant hypertext system for personal computers , was developed by Peter J. Brown at the University of Kent in 1982. In 1980, Roberto Busa , an Italian Jesuit priest and one of

415-477: A 'hypertext' (meaning editing) interface to the public for the first time, in what has come to be known as " The Mother of All Demos ". In 1971 a system called Scrapbook , produced by David Yates and his team at the UK's National Physical Laboratory , went live. It was an information storage and retrieval system that included what would now be called word processing, e-mail and hypertext. ZOG , an early hypertext system,

498-614: A change from linear, structured and hierarchical forms of representing and understanding the world into fractured, decentralized and changeable media based on the technological concept of hypertext links. In the 1990s, women and feminist artists took advantage of hypertext and produced dozens of works. Linda Dement 's Cyberflesh Girlmonster a hypertext CD-ROM that incorporates images of women's body parts and remixes them to create new monstrous yet beautiful shapes. Caitlin Fisher's award-winning online hypertext novella These Waves of Girls (2001)

581-606: A few related authors. In 1983, Ben Shneiderman at the University of Maryland Human - Computer Interaction Lab led a group that developed the HyperTies system that was commercialized by Cognetics Corporation . They studied many designs before adopting the blue color for links . Hyperties was used to create the July 1988 issue of the Communications of the ACM as a hypertext document and then

664-423: A given content size is likely to reduce growth; access controls restricting editing to registered users tends to reduce growth; a lack of such access controls tends to fuel new user registration; and that a higher ratio of administrators to regular users has no significant effect on content or population growth. Joint authorship of articles, in which different users participate in correcting, editing, and compiling

747-573: A hypertext document usually replace the current piece of hypertext with the destination document. A lesser known feature is StretchText , which expands or contracts the content in place, thereby giving more control to the reader in determining the level of detail of the displayed document. Some implementations support transclusion , where text or other content is included by reference and automatically rendered in place. Hypertext can be used to support very complex and dynamic systems of linking and cross-referencing. The most famous implementation of hypertext

830-443: A link to view that specific revision. A diff (short for "difference") feature may be available, which highlights the changes between any two revisions. The edit history view in many wiki implementations will include edit summaries written by users when submitting changes to a page. Similar to the function of a log message in a revision control system, an edit summary is a short piece of text which summarizes and perhaps explains

913-406: A long period. In addition to using the approach of soft security for protecting themselves, larger wikis may employ sophisticated methods, such as bots that automatically identify and revert vandalism. For example, on Misplaced Pages, the bot ClueBot NG uses machine learning to identify likely harmful changes, and reverts these changes within minutes or even seconds. Disagreements between users over

996-542: A new hypertext project in response to a request for a simple, immediate, information-sharing facility, to be used among physicists working at CERN and other academic institutions. He called the project "WorldWideWeb". HyperText is a way to link and access information of various kinds as a web of nodes in which the user can browse at will. Potentially, HyperText provides a single user-interface to many large classes of stored information, such as reports, notes, data-bases, computer documentation and on-line systems help. We propose

1079-491: A page or set of pages to maintain quality. A person willing to maintain pages will be alerted of modifications to them, allowing them to verify the validity of new editions quickly. Such a feature is often called a watchlist . Some wikis also implement patrolled revisions , in which editors with the requisite credentials can mark edits as being legitimate. A flagged revisions system can prevent edits from going live until they have been reviewed. Wikis may allow any person on

1162-426: A page to an older version to rectify a mistake, or counteract a malicious or inappropriate edit to its content. These stores are typically presented for each page in a list, called a "log" or "edit history", available from the page via a link in the interface. The list displays metadata for each revision to the page, such as the time and date of when it was stored, and the name of the person who created it, alongside

1245-439: A page was displayed, any instance of a camel case phrase would be transformed into a link to another page named with the same phrase. While this system made it easy to link to pages, it had the downside of requiring pages to be named in a form deviating from standard spelling, and titles of a single word required abnormally capitalizing one of the letters (e.g. "WiKi" instead of "Wiki"). Some wiki implementations attempt to improve

1328-653: A read-only state. On February 1, 2015, Cunningham announced that the Wiki had been rewritten as a single-page application and migrated to the new Federated Wiki . When moved to read-only, the WikiWikiWeb's WelcomeVisitors page contained the following description in the first two paragraphs: Welcome to WikiWikiWeb , also known as "Wiki". A lot of people had their first wiki experience here. This community has been around since 1995 and consists of many people. We always accept newcomers with valuable contributions. If you haven't used

1411-500: A relatively crude fashion — by creating chains of entire microfilm frames — the Memex is regarded only as a proto-hypertext device, but it is fundamental to the history of hypertext because it directly inspired the invention of hypertext by Ted Nelson and Douglas Engelbart. In 1965, Ted Nelson coined the terms 'hypertext' and 'hypermedia' as part of a model he developed for creating and using linked content (first published reference 1965). He later worked with Andries van Dam to develop

1494-552: A replacement for hypertextual narrative. Critics of hypertext claim that it inhibits the old, linear, reader experience by creating several different tracks to read on. This can also been seen as contributing to a postmodernist fragmentation of worlds. In some cases, hypertext may be detrimental to the development of appealing stories (in the case of hypertext Gamebooks ), where ease of linking fragments may lead to non-cohesive or incomprehensible narratives. However, they do see value in its ability to present several different views on

1577-416: A rich text editing mode. This is usually implemented, using JavaScript , as an interface which translates formatting instructions chosen from a toolbar into the corresponding wiki markup or HTML. This is generated and submitted to the server transparently , shielding users from the technical detail of markup editing and making it easier for them to change the content of pages. An example of such an interface

1660-500: A series of scripts which operate an existing web server , a standalone application server that runs on one or more web servers, or in the case of personal wikis , run as a standalone application on a single computer. Some wikis use flat file databases to store page content, while others use a relational database , as indexed database access is faster on large wikis, particularly for searching. Wikis can also be created on wiki hosting services (also known as wiki farms ), where

1743-422: A single website, but rather to a mass of user-editable pages or sites so that a single website is not "a wiki" but "an instance of wiki". In this concept of wiki federation, in which the same content can be hosted and edited in more than one location in a manner similar to distributed version control , the idea of a single discrete "wiki" no longer made sense. The software which powers a wiki may be implemented as

SECTION 20

#1732838057066

1826-443: A system called WikiNodes . A WikiNode is a page on a wiki which describes and links to other, related wikis. Some wikis operate a structure of neighbors and delegates , wherein a neighbor wiki is one which discusses similar content or is otherwise of interest, and a delegate wiki is one which has agreed to have certain content delegated to it. WikiNode networks act as webrings which may be navigated from one node to another to find

1909-530: A term in natural language could be wrapped in special characters to turn it into a link without modifying it. The concept was given the name in its first implementation, in UseModWiki in February 2001. In that implementation, link terms were wrapped in a double set of square brackets, for example [[Kingdom of France]] . This syntax was adopted by a number of later wiki engines. It is typically possible for users of

1992-492: A wiki before, be prepared for a bit of CultureShock . The usefulness of Wiki is in the freedom, simplicity, and power it offers. This site's primary focus is PeopleProjectsAndPatterns in SoftwareDevelopment . However, it is more than just an InformalHistoryOfProgrammingIdeas . It started there, but the theme has created a culture and DramaticIdentity all its own. All Wiki content is WorkInProgress . Most of all, this

2075-434: A wiki to create links to pages that do not yet exist, as a way to invite the creation of those pages. Such links are usually differentiated visually in some fashion, such as being colored red instead of the default blue, which was the case in the original WikiWikiWeb, or by appearing as a question mark next to the linked words. WikiWikiWeb was the first wiki. Ward Cunningham started developing it in 1994, and installed it on

2158-401: A wiki which addresses a specific subject. The syntax used to create internal hyperlinks varies between wiki implementations. Beginning with the WikiWikiWeb in 1995, most wikis used camel case to name pages, which is when words in a phrase are capitalized and the spaces between them removed. In this system, the phrase "camel case" would be rendered as "CamelCase". In early wiki engines, when

2241-454: A wiki's enforcement of certain rules, such as anti-bias, verifiability, reliable sourcing, and no-original-research policies, could pose legal risks. When defamation occurs on a wiki, theoretically, all users of the wiki can be held liable, because any of them had the ability to remove or amend the defamatory material from the "publication". It remains to be seen whether wikis will be regarded as more akin to an internet service provider , which

2324-468: Is a forum where people share ideas! It changes as people come and go. Much of the information here is subjective. If you are looking for a dedicated reference site, try WikiPedia ; WikiIsNotWikipedia ! Cunningham came up with the name WikiWikiWeb because he remembered a Honolulu International Airport counter employee who told him to take the Wiki Wiki Shuttle , a shuttle bus line that runs between

2407-651: Is easy to correct mistakes or harmful changes, rather than attempting to prevent them from happening in the first place. This allows them to be very open while providing a means to verify the validity of recent additions to the body of pages. Most wikis offer a recent changes page which shows recent edits, or a list of edits made within a given time frame. Some wikis can filter the list to remove edits flagged by users as "minor" and automated edits. The version history feature allows harmful changes to be reverted quickly and easily. Some wiki engines provide additional content control, allowing remote monitoring and management of

2490-424: Is generally not held liable due to its lack of control over publications' contents, than a publisher. It has been recommended that trademark owners monitor what information is presented about their trademarks on wikis, since courts may use such content as evidence pertaining to public perceptions, and they can edit entries to rectify misinformation. Hypertext "(...)'Hypertext' is a recent coinage. 'Hyper-'

2573-587: Is much less used. Instead they use the strange term "interactive multimedia": this is four syllables longer, and does not express the idea of extending hypertext. Hypertext documents can either be static (prepared and stored in advance) or dynamic (continually changing in response to user input, such as dynamic web pages ). Static hypertext can be used to cross-reference collections of data in documents, software applications , or books on CDs . A well-constructed system can also incorporate other user-interface conventions, such as menus and command lines. Links used in

WikiWikiWeb - Misplaced Pages Continue

2656-501: Is not a single wiki but rather a collection of hundreds of wikis, with each one pertaining to a specific language. The English-language Misplaced Pages has the largest collection of articles, standing at 6,917,210 as of November 2024. In their 2001 book The Wiki Way: Quick Collaboration on the Web , Cunningham and co-author Bo Leuf described the essence of the wiki concept: Some wikis will present users with an edit button or link directly on

2739-509: Is set in three time periods of the protagonist exploring polymorphous perversity enacted in her queer identity through memory. The story is written as a reflection diary of the interconnected memories of childhood, adolescence, and adulthood. It consists of an associated multi-modal collection of nodes includes linked text, still and moving images, manipulable images, animations, and sound clips. Adrienne Eisen (pen name for Penelope Trunk ) wrote hypertexts that were subversive narrative journeys into

2822-407: Is sometimes also used for wikis that cover not just a city, but a small town or an entire region. Such a wiki contains information about specific instances of things, ideas, people and places. Such highly localized information might be appropriate for a wiki targeted at local viewers, and could include: A study of several hundred wikis in 2008 showed that a relatively high number of administrators for

2905-478: Is specified, an implied license to read and add content to a wiki may be deemed to exist on the grounds of business necessity and the inherent nature of a wiki. Wikis and their users can be held liable for certain activities that occur on the wiki. If a wiki owner displays indifference and forgoes controls (such as banning copyright infringers) that they could have exercised to stop copyright infringement, they may be deemed to have authorized infringement, especially if

2988-532: Is still followed by some more recent wiki software, whereas others, such as the MediaWiki software that powers Misplaced Pages , allow links without camel case. The software and website were developed in 1994 by Cunningham in order to make the exchange of ideas between programmers easier. This concept was based on the ideas developed in HyperCard stacks that Cunningham built in the late 1980s. On March 25, 1995, he installed

3071-455: Is the VisualEditor in MediaWiki , the wiki engine used by Misplaced Pages. WYSIWYG editors may not provide all the features available in wiki markup, and some users prefer not to use them, so a source editor will often be available simultaneously. Some wiki implementations keep a record of changes made to wiki pages, and may store every version of the page permanently. This allows authors to revert

3154-524: Is the World Wide Web , written in the final months of 1990 and released on the Internet in 1991. In 1941, Jorge Luis Borges published " The Garden of Forking Paths ", a short story that is often considered an inspiration for the concept of hypertext. In 1945, Vannevar Bush wrote an article in The Atlantic Monthly called " As We May Think ", about a futuristic proto-hypertext device he called

3237-462: Is used in the mathematical sense of extension and generality (as in 'hyperspace,' 'hypercube') rather than the medical sense of 'excessive' ('hyperactivity'). There is no implication about size — a hypertext could contain only 500 words or so. 'Hyper-' refers to structure and not size." The English prefix "hyper-" comes from the Greek prefix "ὑπερ-" and means "over" or "beyond"; it has a common origin with

3320-596: The Hypertext Editing System (text editing) in 1967 at Brown University . It was implemented using the terminal IBM 2250 with a light pen which was provided as a pointing device . By 1976, its successor FRESS was used in a poetry class in which students could browse a hyperlinked set of poems and discussion by experts, faculty and other students, in what was arguably the world's first online scholarly community which van Dam says "foreshadowed wikis, blogs and communal documents of all kinds". Ted Nelson said in

3403-560: The Internet domain c2.com on March 25, 1995. Cunningham gave it the name after remembering a Honolulu International Airport counter employee telling him to take the " Wiki Wiki Shuttle " bus that runs between the airport's terminals, later observing that "I chose wiki-wiki as an alliterative substitute for 'quick' and thereby avoided naming this stuff quick-web." Cunningham's system was inspired by his having used Apple 's hypertext software HyperCard , which allowed users to create interlinked "stacks" of virtual cards. HyperCard, however,

WikiWikiWeb - Misplaced Pages Continue

3486-550: The Portland Pattern Repository website discussing software design patterns . The name WikiWikiWeb originally also applied to the wiki software that operated the website, written in the Perl programming language and later renamed to "WikiBase". Hyperlinks between pages on WikiWikiWeb are created by joining capitalized words together, a technique referred to as camel case . This convention of wiki markup formatting

3569-530: The United States Court of Appeals for the Seventh Circuit , used to post court rules and allow practitioners to comment and ask questions. The United States Patent and Trademark Office operates Peer-to-Patent , a wiki to allow the public to collaborate on finding prior art relevant to the examination of pending patent applications. Queens , New York has used a wiki to allow citizens to collaborate on

3652-734: The WikiWikiWeb , Memory Alpha , Wikivoyage , and previously Susning.nu , a Swedish-language knowledge base. Medical and health-related wiki examples include Ganfyd , an online collaborative medical reference that is edited by medical professionals and invited non-medical experts. Many wiki communities are private, particularly within enterprises . They are often used as internal documentation for in-house systems and applications. Some companies use wikis to allow customers to help produce software documentation. A study of corporate wiki users found that they could be divided into "synthesizers" and "adders" of content. Synthesizers' frequency of contribution

3735-494: The internet which is collaboratively edited and managed by its audience directly through a web browser . A typical wiki contains multiple pages that can either be edited by the public or limited to use within an organization for maintaining its internal knowledge base . Wikis are powered by wiki software , also known as wiki engines. Being a form of content management system , these differ from other web-based systems such as blog software or static site generators in that

3818-491: The server-side software is implemented by the wiki farm owner, and may do so at no charge in exchange for advertisements being displayed on the wiki's pages. Some hosting services offer private, password-protected wikis requiring authentication to access. Free wiki farms generally contain advertising on every page. The four basic types of users who participate in wikis are readers, authors, wiki administrators and system administrators. System administrators are responsible for

3901-468: The 1960s that he began implementation of a hypertext system he theorized, which was named Project Xanadu , but his first and incomplete public release was finished much later, in 1998. Douglas Engelbart independently began working on his NLS system in 1962 at Stanford Research Institute, although delays in obtaining funding, personnel, and equipment meant that its key features were not completed until 1968. In December of that year, Engelbart demonstrated

3984-420: The 1990s. Judy Malloy 's Uncle Roger (1986) and Michael Joyce 's afternoon, a story (1987) are generally considered the first works of hypertext fiction. An advantage of writing a narrative using hypertext technology is that the meaning of the story can be conveyed through a sense of spatiality and perspective that is arguably unique to digitally networked environments. An author's creative use of nodes,

4067-516: The Internet began the creation of the Web on the Internet. As new web browsers were released, traffic on the World Wide Web quickly exploded from only 500 known web servers in 1993 to over 10,000 in 1994. As a result, all previous hypertext systems were overshadowed by the success of the Web, even though it lacked many features of those earlier systems, such as integrated browsers/editors (a feature of

4150-614: The World Wide Web series of conferences, organized by IW3C2 , also include many papers of interest. There is a list on the Web with links to all conferences in the series. Hypertext writing has developed its own style of fiction, coinciding with the growth and proliferation of hypertext development software and the emergence of electronic networks. Hypertext fiction is one of earliest genres of electronic literature , or literary works that are designed to be read in digital media. Two software programs specifically designed for literary hypertext, Storyspace and Intermedia , became available in

4233-498: The academic community for sharing and dissemination of information across institutional and international boundaries. In those settings, they have been found useful for collaboration on grant writing , strategic planning , departmental documentation, and committee work. In the mid-2000s, the increasing trend among industries toward collaboration placed a heavier impetus upon educators to make students proficient in collaborative work, inspiring even greater interest in wikis being used in

4316-420: The airport's terminals. "Wiki Wiki" is a reduplication of "wiki", a Hawaiian language word for "quick". Cunningham's idea was to make WikiWikiWeb's pages quickly editable by its users, so he initially thought about calling it "QuickWeb", but later changed his mind and dubbed it "WikiWikiWeb". Wiki A wiki ( / ˈ w ɪ k i / WI -kee ) is a form of hypertext publication on

4399-405: The branched literature writing software Storyspace , were also demonstrated. Meanwhile, Nelson (who had been working on and advocating his Xanadu system for over two decades) convinced Autodesk to invest in his revolutionary ideas. The project continued at Autodesk for four years, but no product was released. In 1989, Tim Berners-Lee, then a scientist at CERN , proposed and later prototyped

4482-426: The change, for example "Corrected grammar" or "Fixed table formatting to not extend past page width". It is not inserted into the article's main text. Traditionally, wikis offer free navigation between their pages via hypertext links in page text, rather than requiring users to follow a formal or structured navigation scheme. Users may also create indexes or table of contents pages, hierarchical categorization via

4565-598: The classroom. Wikis have found some use within the legal profession and within the government. Examples include the Central Intelligence Agency 's Intellipedia , designed to share and collect intelligence assessments , DKosopedia , which was used by the American Civil Liberties Union to assist with review of documents about the internment of detainees in Guantánamo Bay ; and the wiki of

4648-1107: The content is created without any defined owner or leader. Wikis have little inherent structure, allowing one to emerge according to the needs of the users. Wiki engines usually allow content to be written using a lightweight markup language and sometimes edited with the help of a rich-text editor . There are dozens of different wiki engines in use, both standalone and part of other software, such as bug tracking systems . Some wiki engines are free and open-source , whereas others are proprietary . Some permit control over different functions (levels of access); for example, editing rights may permit changing, adding, or removing material. Others may permit access without enforcing access control. Further rules may be imposed to organize content. In addition to hosting user-authored content, wikis allow those users to interact, hold discussions, and collaborate. There are hundreds of thousands of wikis in use , both public and private, including wikis functioning as knowledge management resources, note-taking tools, community websites , and intranets . Ward Cunningham ,

4731-424: The content or appearance of pages may cause edit wars , where competing users repetitively change a page back to a version that they favor. Some wiki software allows administrators to prevent pages from being editable until a decision has been made on what version of the page would be most appropriate. Some wikis may be subject to external structures of governance which address the behavior of persons with access to

4814-420: The content. Proponents maintain that these issues will be caught and rectified by a wiki's community of users. High editorial standards in medicine and health sciences articles, in which users typically use peer-reviewed journals or university textbooks as sources, have led to the idea of expert-moderated wikis. Wiki implementations retaining and allowing access to specific versions of articles has been useful to

4897-435: The design and planning of a local park. Cornell Law School founded a wiki-based legal dictionary called Wex , whose growth has been hampered by restrictions on who can edit. In academic contexts, wikis have also been used as project collaboration and research support systems. A city wiki or local wiki is a wiki used as a knowledge base and social network for a specific geographical locale. The term city wiki

4980-445: The developer of the first wiki software, WikiWikiWeb , originally described wiki as "the simplest online database that could possibly work". " Wiki " (pronounced [wiki] ) is a Hawaiian word meaning "quick". The online encyclopedia project Misplaced Pages is the most popular wiki-based website, as well being one of the internet's most popular websites , having been ranked consistently as such since at least 2007. Misplaced Pages

5063-412: The display of camel case page titles and links by reinserting spaces and possibly also reverting to lower case, but this simplistic method is not able to correctly present titles of mixed capitalization. For example, " Kingdom of France " as a page title would be written as "KingdomOfFrance", and displayed as "Kingdom Of France". To avoid this problem, the syntax of wiki markup gained free links , wherein

Some copyright issues can be alleviated through the use of an open content license. Version 2 of the GNU Free Documentation License includes a specific provision for wiki relicensing, and Creative Commons licenses are also popular. When no license

5229-846: The first commercial electronic book Hypertext Hands-On! . In August 1987, Apple Computer released HyperCard for the Macintosh line at the MacWorld convention . Its impact, combined with interest in Peter J. Brown's GUIDE (marketed by OWL and released earlier that year) and Brown University's Intermedia , led to broad interest in and enthusiasm for hypertext, hypermedia, databases, and new media in general. The first ACM Hypertext (hyperediting and databases) academic conference took place in November 1987, in Chapel Hill NC, where many other applications, including

5312-516: The implementation of a simple scheme to incorporate several different servers of machine-stored information already available at CERN, including an analysis of the requirements for information access needs by experiments... A program which provides access to the hypertext world we call a browser. ― T. Berners-Lee, R. Cailliau, 12 November 1990, CERN In 1992, Lynx was born as an early Internet web browser. Its ability to provide hypertext links within documents that could reach into documents anywhere on

5395-405: The installation and maintenance of the wiki engine and the container web server. Wiki administrators maintain content and, through having elevated privileges , are granted additional functions (including, for example, preventing edits to pages, deleting pages, changing users' access rights, or blocking them from editing). Wikis are generally designed with a soft security philosophy in which it

5478-402: The link had their systems infected with the worm. Some wiki engines offer a blacklist feature which prevents users from adding hyperlinks to specific sites that have been placed on the list by the wiki's administrators. The English Misplaced Pages has the largest user base among wikis on the World Wide Web and ranks in the top 10 among all Web sites in terms of traffic. Other large wikis include

5561-552: The most famous wiki site , launched in January 2001 and entering the top ten most popular websites in 2007. In the early 2000s, wikis were increasingly adopted in enterprise as collaborative software. Common uses included project communication, intranets , and documentation, initially for technical users. Some companies use wikis as their collaborative software and as a replacement for static intranets, and some schools and universities use wikis to enhance group learning . On March 15, 2007,

5644-636: The original WorldWideWeb browser, which was not carried over into most of the other early Web browsers). Besides the already mentioned Project Xanadu , Hypertext Editing System , NLS , HyperCard , and World Wide Web, there are other noteworthy early implementations of hypertext, with different feature sets: Among the top academic conferences for new research in hypertext is the annual ACM Conference on Hypertext and Social Media . The Electronic Literature Organization hosts annual conferences discussing hypertext fiction , poetry and other forms of electronic literature . Although not exclusively about hypertext,

5727-531: The page being viewed. This will open an interface for writing, formatting, and structuring page content. The interface may be a source editor, which is text-based and employs a lightweight markup language (also known as wikitext , wiki markup , or wikicode ), or a visual editor . For example, in a source editor, starting lines of text with asterisks could create a bulleted list . The syntax and features of wiki markup languages for denoting style and structure can vary greatly among implementations . Some allow

5893-538: The prefix "super-" which comes from Latin. It signifies the overcoming of the previous linear constraints of written text. The term "hypertext" is often used where the term " hypermedia " might seem appropriate. In 1992, author Ted Nelson  – who coined both terms in 1963  – wrote: By now the word "hypertext" has become generally accepted for branching and responding text, but the corresponding word "hypermedia", meaning complexes of branching and responding graphics, movies and sound – as well as text –

5976-459: The same subject in a simple way. This echoes the arguments of 'medium theorists' like Marshall McLuhan who look at the social and psychological impacts of the media. New media can become so dominant in public culture that they effectively create a "paradigm shift" as people have shifted their perceptions, understanding of the world, and ways of interacting with the world and each other in relation to new technologies and media. So hypertext signifies

6059-427: The scientific community, by allowing expert peer reviewers to provide links to trusted version of articles which they have analyzed. Trolling and cybervandalism on wikis, where content is changed to something deliberately incorrect or a hoax , offensive material or nonsense is added, or content is maliciously removed, can be a major problem. On larger wiki sites it is possible for such changes to go unnoticed for

6142-509: The self-contained units of meaning in a hypertextual narrative, can play with the reader's orientation and add meaning to the text. One of the most successful computer games, Myst , was first written in HyperCard. The game was constructed as a series of Ages, each Age consisting of a separate HyperCard stack. The full stack of the game consists of over 2500 cards. In some ways, Myst redefined interactive fiction, using puzzles and exploration as

6225-415: The software on his company's (Cunningham & Cunningham) website: c2.com. The site was frequently referred to by its users as simply "Wiki"; users of the early network of wiki sites that followed in the 1990s and 2000s followed a convention that using the word with a capitalized W referred exclusively to WikiWikiWeb. In December 2014, WikiWikiWeb came under the attack of vandals , and had to be put into

6308-472: The system, for example in academic contexts. As most wikis allow the creation of hyperlinks to other sites and services, the addition of malicious hyperlinks, such as sites infected with malware , can also be a problem. For example, in 2006 a German Misplaced Pages article about the Blaster Worm was edited to include a hyperlink to a malicious website, and users of vulnerable Microsoft Windows systems who followed

6391-673: The use of HTML Tooltip Hypertext Markup Language and CSS Tooltip Cascading Style Sheets , while others prevent the use of these to foster uniformity in appearance. A short section of Alice's Adventures in Wonderland rendered in wiki markup: "I've had nothing yet," Alice replied in an offended tone, "so I can't take more." "You mean you can't take less ," said the Hatter. "It's very easy to take more than nothing." While wiki engines have traditionally offered source editing to users, in recent years some implementations have added

6474-568: The web to edit their content without having to register an account on the site first ( anonymous editing ), or require registration as a condition of participation. On implementations where an administrator is able to restrict editing of a page or group of pages to a specific group of users, they may have the option to prevent anonymous editing while allowing it for registered users. Critics of publicly editable wikis argue that they could be easily tampered with by malicious individuals, or even by well-meaning but unskilled users who introduce errors into

6557-550: The wiki is primarily used to infringe copyrights or obtains a direct financial benefit, such as advertising revenue, from infringing activities. In the United States, wikis may benefit from Section 230 of the Communications Decency Act , which protects sites that engage in " Good Samaritan " policing of harmful material, with no requirement on the quality or quantity of such self-policing. It has also been argued that

6640-414: The word wiki was listed in the online Oxford English Dictionary . In the late 1990s and early 2000s, the word "wiki" was used to refer to both user-editable websites and the software that powers them, and the latter definition is still occasionally in use. By 2014, Ward Cunningham's thinking on the nature of wikis had evolved, leading him to write that the word "wiki" should not be used to refer to

6723-629: Was affected more by their impact on other wiki users, while adders' contribution frequency was affected more by being able to accomplish their immediate work. From a study of thousands of wiki deployments, Jonathan Grudin concluded careful stakeholder analysis and education are crucial to successful wiki deployment. In 2005, the Gartner Group, noting the increasing popularity of wikis, estimated that they would become mainstream collaboration tools in at least 50% of companies by 2009. Wikis can be used for project management . Wikis have also been used in

6806-611: Was developed at Carnegie Mellon University during the 1970s, used for documents on Nimitz class aircraft carriers, and later evolving as KMS (Knowledge Management System). The first hypermedia application is generally considered to be the Aspen Movie Map , implemented in 1978. The Movie Map allowed users to arbitrarily choose which way they wished to drive in a virtual cityscape, in two seasons (from actual photographs) as well as 3-D polygons . In 1980, Tim Berners-Lee created ENQUIRE , an early hypertext database system somewhat like

6889-478: Was single-user, and Cunningham was inspired to build upon the ideas of Vannevar Bush , the inventor of hypertext, by allowing users to "comment on and change one another's text." Cunningham says his goals were to link together people's experiences to create a new literature to document programming patterns , and to harness people's natural desire to talk and tell stories with a technology that would feel comfortable to those not used to "authoring". Misplaced Pages became
