Hypermedia

Source: Wikipedia, the free encyclopedia.

Hypermedia, an extension of the term 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. It is also related to the field of electronic literature. The term was first used in a 1965 article written by Ted Nelson.[1][2]

The

cinema
presentation is an example of standard multimedia due to the absence of hyperlinks.

The first hypermedia work was, arguably, the

voice command devices and voice browsing.[3]

Development tools

Hypermedia may be developed in a number of ways. Any

Macromedia Authorware, and MatchWare Mediator may be used to create stand-alone hypermedia applications, with emphasis on entertainment content. Some database software, such as Visual FoxPro and FileMaker Developer
, may be used to develop stand-alone hypermedia applications, with emphasis on educational and business content management.

Hypermedia applications may be developed on embedded devices for the mobile and the

Scalable Vector Graphics (SVG) specification from W3C (World Wide Web Consortium). Software applications, such as Ikivo Animator and Inkscape, simplify the development of hypermedia content based on SVG. Embedded devices, such as the iPhone
, natively support SVG specifications and may be used to create mobile and distributed hypermedia applications.

Hyperlinks may also be added to

PDF documents such as Adobe InDesign for creating and Adobe Acrobat for editing. Hyper Publish is a tool specifically designed and optimized for hypermedia and hypertext management. Any HTML editor may be used to build HTML files, accessible by any web browser. CD/DVD authoring tools, such as DVD Studio Pro, may be used to hyperlink the content of DVDs for DVD players or web links when the disc is played on a personal computer
connected to the internet.

Learning

There have been a number of theories concerning hypermedia and learning. One important claim in the literature on hypermedia and learning is that it offers more control over the instructional environment for the reader or student. Another claim is that it levels the playing field among students of varying abilities and enhances collaborative learning. A claim from psychology includes the notion that hypermedia more closely models the structure of the brain, in comparison with printed text.[4]

Application programming interfaces

Hypermedia is used as a medium and constraint in certain

REST application architecture where a client interacts with the server entirely through hypermedia provided dynamically by application servers. This means that in theory no API documentation is needed, because the client needs no prior knowledge about how to interact with any particular application or server beyond a generic understanding of hypermedia. In other service-oriented architectures (SOA), clients and servers interact through a fixed interface shared through documentation or an interface description language
(IDL).
