Douglas Noel Adams was an English author, humourist, and screenwriter, best known as the creator of The Hitchhiker's Guide to the Galaxy (HHGTTG). Originally a 1978 BBC radio comedy, The Hitchhiker's Guide to the Galaxy developed into a "trilogy" of five books which sold more than 15 million copies in his lifetime. It was further developed into a television series, several stage plays, comics, a video game, and a 2005 feature film. Adams's contribution to UK radio is commemorated in The Radio Academy's Hall of Fame.
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.
In computer science, transclusion is the inclusion of part or all of an electronic document into one or more other documents by reference via hypertext. Transclusion is usually performed when the referencing document is displayed, and is normally automatic and transparent to the end user. The result of transclusion is a single integrated document made of parts assembled dynamically from separate sources, possibly stored on different computers in disparate places.
Theodor Holm Nelson is an American pioneer of information technology, philosopher, and sociologist. He coined the terms hypertext and hypermedia in 1963 and published them in 1965. According to a 1997 Forbes profile, Nelson "sees himself as a literary romantic, like a Cyrano de Bergerac, or 'the Orson Welles of software'."
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 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. A user following hyperlinks is said to navigate or browse the hypertext.
Dirk Gently's Holistic Detective Agency is a humorous detective novel by English writer Douglas Adams, published in 1987. It is described by the author on its cover as a "thumping good detective-ghost-horror-who dunnit-time travel-romantic-musical-comedy-epic".
Project Xanadu was the first hypertext project, founded in 1960 by Ted Nelson. Administrators of Project Xanadu have declared it superior to the World Wide Web, with the mission statement: "Today's popular software simulates paper. The World Wide Web trivialises our original hypertext model with one-way ever-breaking links and no management of version or contents."
Dirk Gently is a fictional character created by English writer Douglas Adams and featured in the books Dirk Gently's Holistic Detective Agency, The Long Dark Tea-Time of the Soul and The Salmon of Doubt. He is portrayed as a pudgy man who normally wears a heavy old light brown suit, red checked shirt with a green striped tie, long leather coat, red hat and thick metal-rimmed spectacles. "Dirk Gently" is not the character's real name. It is noted early on in the first book that it is a pseudonym for "Svlad Cjelli". Dirk himself states that the name has a "Scottish dagger feel" to it.
This article presents a timeline of hypertext technology, including "hypermedia" and related human–computer interaction projects and developments from 1945 on. The term hypertext is credited to the author and philosopher Ted Nelson.
Hypermedia, an extension of hypertext, is a nonlinear medium of information that includes graphics, audio, video, plain text and hyperlinks. This designation contrasts with the broader term multimedia, which may include non-interactive linear presentations as well as hypermedia. The term was first used in a 1965 article written by Ted Nelson. Hypermedia is a type of multimedia that features interactive elements, such as hypertext, buttons, or interactive images and videos, allowing users to navigate and engage with content in a non-linear manner.
Intertwingularity is a term coined by Ted Nelson to express the complexity of interrelations in human knowledge.
In computing, the desktop metaphor is an interface metaphor which is a set of unifying concepts used by graphical user interfaces to help users interact more easily with the computer. The desktop metaphor treats the computer monitor as if it is the top of the user's desk, upon which objects such as documents and folders of documents can be placed. A document can be opened into a window, which represents a paper copy of the document placed on the desktop. Small applications called desk accessories are also available, such as a desk calculator or notepad, etc.
Coined in 1987, the term Knowledge Navigator described a future computing system and how people might use it to navigate worlds of knowledge. In a sense, the user is actually the “Knowledge Navigator,” though the term often refers to the system’s primary interface, a tablet computer. That part often stands for the whole system. The term is also the title of an Apple “vision video.” The concept was described by former Apple Computer CEO John Sculley and John A. Byrne in their book, Odyssey: Pepsi to Apple.
“A future-generation Macintosh, which we should have early in the twenty-first century, might well be a wonderful fantasy machine called the Knowledge Navigator, a discoverer of worlds, a tool as galvanizing as the printing press. Individuals could use it to drive through libraries, museums, databases, or institutional archives. This tool wouldn't just take you to the doorstep of these great resources as sophisticated computers do now; it would invite you deep inside its secrets, interpreting and explaining—converting vast quantities of information into personalized and understandable knowledge.”
ZigZag is a data model, invented by Ted Nelson, that deconstructs the spreadsheet to allow irregular relations, at the same time generalizing the idea to multiple dimensions.
The Mundaneum was an institution which aimed to gather together all the world's knowledge and classify it according to a system called the Universal Decimal Classification. It was developed at the turn of the 20th century by Belgian lawyers Paul Otlet and Henri La Fontaine. The Mundaneum has been identified as a milestone in the history of data collection and management, and as a precursor to the Internet.
Computer Lib/Dream Machines is a 1974 book by Ted Nelson, printed as a two-front-cover paperback to indicate its "intertwingled" nature. Originally self-published by Nelson, it was republished with a foreword by Stewart Brand in 1987 by Microsoft Press.
Hypertext is text displayed on a computer or other electronic device with references (hyperlinks) to other text that the reader can immediately access, usually by a mouse click or keypress sequence. Early conceptions of hypertext defined it as text that could be connected by a linking system to a range of other documents that were stored outside that text. In 1934 Belgian bibliographer, Paul Otlet, developed a blueprint for links that telescoped out from hypertext electrically to allow readers to access documents, books, photographs, and so on, stored anywhere in the world.
