Definition
- A hypertext is a non-linear text that connects various elements (nodes, pages) through links.
- From the Wikipedia: “In computing, hypertext is a user interface paradigm for displaying documents which, according to an early definition (Nelson 1970), "branch or perform on request." The most frequently discussed form of hypertext document contains automated cross-references to other documents called hyperlinks. Selecting a hyperlink causes the computer to load and display the linked document.”
- Hypertext is not just HTML.
- Hypertext systems allow users to author, edit and follow links between different bodies of text. Hypermedia systems, are similar to hypertext systems, except that the user can use other forms of media as well.
Hypertext in education
Hypertext requires the reader to be an active participant in the evolution of the learning path and therefore are of interest to various constructivist designs.
- Cognitive flexibility theory that focuses on the nature of learning in complex and ill-structured domains and builds on top of cognitivist thinking shows interest for hypertext technology.
- Exploratory learning designs
- Why do we add Hypertext to the Category:Instructional design models ? Because there are people who believe that one can learn by surfing through hypertext. It's the constructivist "spray and pray" equivalent to the "page turning" design idea popular with some LMS users ....
History
This is a very incomplete time-line:
- 1945: V. Bush, As We May Think
- 1965: Ted Nelson invents the word "Hypertext"
- 1968: Engelbart demoes "HyperMedia" over the network
- 1981: Start of Ted Nelson's Xanadu project which never managed to take off, however there finally was an available implementation in 1999 (?)
- 1992 First commercial hypertext system by Eastgate (still sold as Storyspace)
- 1989: Tim Berners-Lee builds the first prototype of the WWW and invents HTML, formally as a SGML application.
- 1991: Gopher (Menu-based navigation through files and services on the Internet)
- 1992-1993: The WWW starts spreading
- 1992 / 1997 Hytime is a complex SGML application. Hytime is an ISO standard that has rarely been used, but it had a big influence on the definition of more recent Web Standards like XLink.
- Early 90' (?) Adaptive hypertexts
- 1995 Ward Cunningham invented the first [Wikipedia:Wiki|Wiki]. Wikis are probably the only popular [[CMS]s that are compatible with the Hypertext concept.
(To do: add more recent developments + exotic hypertexts)
Examples
There are not many good hypertext examples on the Internet. Some exceptions are:
- The Wikipedia
- Beat's Biblionetz
- The Theory into Practise DataBase (TIP)
Standards
- Internet resource locators (URLs, URNs)
- HTML / XHTML and associated linking mechanisms (e.g. the "A" tag and the "href" attribute)
- XML Linking standards like XLink and associated mechanisms to point to documents and parts of documents (XPointer and XPath)
- Topic Maps
- Some languages based on RDF, e.g. ontology languages like OWL or social software standards like FOAF.
- HyTime
- Text Encoding Initiative Guidelines
Software and technology
- Some gaming engines
- Wikis
- Web-based solutions (also need a Wikipedia:HTTP Server):
- Wikipedia:HTML clients
- Wikipedia:XML clients that support Wikipedia:XLink
- Wikipedia:SVG clients
- Storyspace (quote: "is widely considered the tool of choice for hypertext writers."
- Interactive fiction engines and MUDs/MOOs
- Multimedia authoring system, such as ToolBook and Authorware or earlier systems like HyperCard
- Some concept maps, e.g. the ones that are used to visualize information spaces in search engines like Kartoo, wikis, etc.
