Uses in various technologies

Simple image demonstrating how internal MediaWiki links work (that is, the order of the link's parts) when you want to create a link that displays words differently from the linked page's title: two opening square brackets, the ACTUAL link, a pipe character explained as the necessary divider, the words that are how I want it to APPEAR, and two closing square brackets.


HTMLedit

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 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:

  • The hyperlink starts with an anchor opening tag <a, and includes a hyperlink reference href="https://www.w3.org/" to the URL for the page. (Note that the URL is enclosed in quotes.)
  • The URL is followed by >, marking the end of the anchor opening tag.
  • The words that follow identify what is being linked; this is the only part of the code that is ordinarily visible on the screen when the page is rendered, but when the cursor hovers over the link, many browsers display the target URL somewhere on the screen, such as in the lower left-hand corner.
  • Typically these words are underlined and colored (for example, blue for a link that has not yet been visited and purple for a link already visited).
  • The anchor closing tag (</a>) terminates the hyperlink code.
  • The <a> tag can also consist of various attributes such as the "rel" attribute which specifies the relationship between the current document and linked document.

Webgraph is a graph, formed from web pages as vertices and hyperlinks, as directed edges.

XLink: hyperlinksedit

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, 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.

Wikisedit

While wikis may use HTML-type hyperlinks, the use of wiki markup, a set of lightweight markup languages specifically for wikis, provides a simplified syntax for linking pages within wiki environments – in other words, for creating wikilinks.

The syntax and appearance of wikilinks may vary. Ward Cunningham's original wiki software, the WikiWikiWeb used CamelCase for this purpose. CamelCase was also used in the early version of Wikipedia and is still used in some wikis, such as TiddlyWiki, Trac, and PmWiki. A common markup syntax is the use of double square brackets around the term to be wikilinked. For example, the input "zebras" is converted by wiki software using this markup syntax to a link to a zebras article. Hyperlinks used in wikis are commonly classified as follows:

  • Internal wikilinks or intrawiki links lead to pages within the same wiki website.
  • Interwiki links are simplified markup hyperlinks that lead to pages of other wikis that are associated with the first.
  • External links lead to other webpages (those not covered in the above two cases, wiki or not wiki).

Wikilinks are visibly distinct from other text, and if an internal wikilink leads to a page that does not yet exist, it usually has a different specific visual appearance. For example, in Wikipedia wikilinks are displayed in blue, except those that link to pages that don't yet exist, which are instead shown in red. Another possibility for linking is to display a highlighted clickable question mark after the wikilinked term.

Virtual worldsedit

Hyperlinks are being implemented in various 3D virtual world networks, including those that use the OpenSimulator and Open Cobalt platforms.

Permalinksedit

Permalinks are URLs that are intended to remain unchanged for many years into the future, yielding hyperlink 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 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.

History

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 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 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. M

How hyperlinks work in HTML

Image
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 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 a page number or another element of the PDF, for example, "# page=386 ". Link behavior in web browsers edit 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 dec
