Tag

Tag
(n) A command inserted in a document that specifies how the document, or a portion of the document, should be formatted. Tags are used by all format specifications that store documents as text files. This includes SGML and HTML, (www.webopedia.com).

Example: A web page hosted on a web server or blog server which supports tagging, might have the tags Baseball, Red Sox, Tickets, Away Games, and Discounts. A human reader can probably tell the purpose of the page by quickly scanning the list of tags. Typically, the server would display the tags in a list on that page, with each tag displayed as a web link leading to an index page listing all web pages which use that tag. This allows a reader to locate quickly all pages which have been associated with the term Red Sox. If the server supports tag searching, a reader would be able to find all pages that use a particular set of tags, such as Red Sox and Tickets. If the page's author wishes to reclassify the page, all that is required is for them to change the list of tags. In this case, the author could add the tags Blue Jays, and Paypal to their page. All connections between pages are automatically tracked and updated by the server software. There is no need to relocate the page within a complex hierarchy of categories, ([|http://en.wikipedia.org/).]
