Operator (extension)
Operator was an extension for the Mozilla Firefox web browser. It parses and acts upon a number of microformats, as well as validating them. Operator lets the user access microformats through a number of methods, all of which are optional: a toolbar, a toolbar button, a status bar icon, a location bar icon, or a sidebar. It has native support for several microformats: *adradr spec (postal addresses) *hCard (contact/ address information) *hCalendar (events) *Geo (geographic coordinates) * rel-tag and is extensible, in that users can add new actions for the included microformats, or specify additional microformat recognition. Operator was written by Mike Kaply of IBM. It forms the basis for Firefox 3's microformats API, allowing native support, but has no direct user interface, due to lack of consensus on the implementation in the GUI.

Geo (microformat)
Geo is a microformat used for marking up WGS84 geographical coordinates (latitude;longitude) in (X)HTML. Although termed a "draft" specification, this is a formality, and the format is stable and in widespread use; not least as a sub-set of the published hCalendar and hCard microformat specifications, neither of which is still a draft. Use of Geo allows parsing tools (for example other websites, or Firefox's Operator extension) to extract the locations, and display them using some other website or mapping tool, or to load them into a GPS device, index or aggregate them, or convert them into an alternative format. Usage *If latitude is present, so must be longitude, and vice versa. *The same number of decimal places should be used in each value, including trailing zeroes.''Must'' and ''should'' are used per the IETF document The Geo microformat is applied using three HTML classes. For example, the marked-up text: Belvide: 52.686; -2.193 becomes: Belvide: ; by addin ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Address Bar
In a web browser, the address bar (also location bar or URL bar) is the element that shows the current URL. The user can type a URL into it to navigate to a chosen website. In most modern browsers, non-URLs are automatically sent to a search engine. In a file browser, it serves the same purpose of navigation, but through the file-system hierarchy. Many address bars offer features like autocomplete and a list of suggestions while the address is being typed in. This auto-completion feature bases its suggestions on the browser's history. Some browsers have keyboard shortcuts to auto-complete an address. Features In addition to the URL, some address bars feature icons showing features or information about the site. For websites using a favicon (a small icon that represents the website), a small icon may be present within the address bar, a generic icon appearing if the website does not specify one. The address bar is also used to show the security status of a web page; various des ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Graphical User Interface
The GUI ( "UI" by itself is still usually pronounced . or ), graphical user interface, is a form of user interface that allows users to interact with electronic devices through graphical icons and audio indicator such as primary notation, instead of text-based UIs, typed command labels or text navigation. GUIs were introduced in reaction to the perceived steep learning curve of CLIs ( command-line interfaces), which require commands to be typed on a computer keyboard. The actions in a GUI are usually performed through direct manipulation of the graphical elements. Beyond computers, GUIs are used in many handheld mobile devices such as MP3 players, portable media players, gaming devices, smartphones and smaller household, office and industrial controls. The term ''GUI'' tends not to be applied to other lower-display resolution types of interfaces, such as video games (where HUD (''head-up display'') is preferred), or not including flat screens like volumetric displays because ...

Tag (metadata)
In information systems, a tag is a keyword or term assigned to a piece of information (such as an Internet bookmark, multimedia, database record, or computer file). This kind of metadata helps describe an item and allows it to be found again by browsing or searching. Tags are generally chosen informally and personally by the item's creator or by its viewer, depending on the system, although they may also be chosen from a controlled vocabulary. Tagging was popularized by websites associated with Web 2.0 and is an important feature of many Web 2.0 services. It is now also part of other database systems, desktop applications, and operating systems. Overview People use tags to aid classification, mark ownership, note boundaries, and indicate online identity. Tags may take the form of words, images, or other identifying marks. An analogous example of tags in the physical world is museum object tagging. People were using textual keywords to classify information and objects long b ...

Geographic Coordinate System
The geographic coordinate system (GCS) is a spherical or ellipsoidal coordinate system for measuring and communicating positions directly on the Earth as latitude and longitude. It is the simplest, oldest and most widely used of the various spatial reference systems that are in use, and forms the basis for most others. Although latitude and longitude form a coordinate tuple like a cartesian coordinate system, the geographic coordinate system is not cartesian because the measurements are angles and are not on a planar surface. A full GCS specification, such as those listed in the EPSG and ISO 19111 standards, also includes a choice of geodetic datum (including an Earth ellipsoid), as different datums will yield different latitude and longitude values for the same location. History The invention of a geographic coordinate system is generally credited to Eratosthenes of Cyrene, who composed his now-lost ''Geography'' at the Library of Alexandria in the 3rd century  ...

HCalendar
hCalendar (short for ''HTML iCalendar'') is a microformat standard for displaying a semantic (X)HTML representation of iCalendar-format calendar information about an event, on web pages, using HTML classes and ''rel'' attributes. It allows parsing tools (for example other websites, or browser add-ons like Firefox's Operator extension) to extract the details of the event, and display them using some other website, index or search them, or to load them into a calendar or diary program, for instance. Multiple instances can be displayed as timelines. Example Consider this semi-fictional example: The English Wikipedia was launched on 15 January 2001 with a party from 2-4pm at Jimmy Wales' house (more information). The HTML mark-up might be: The English Wikipedia was launched on 15 January 2001 with a party from 2-4pm at Jimmy Wales' house (more information) hCalendar mark-up may be added using span HTML elements and the classe ...

HCard
hCard is a microformat for publishing the contact details (which might be no more than the name) of people, companies, organizations, and places, in HTML, Atom, RSS, or arbitrary XML. The hCard microformat does this using a 1:1 representation of vCard (RFC 2426) properties and values, identified using HTML classes and ''rel'' attributes. It allows parsing tools (for example other websites, or Firefox's Operator extension) to extract the details, and display them, using some other websites or mapping tools, index or search them, or to load them into an address-book program. In May 2009, Google announced that they would be parsing the hCard, hReview and hProduct microformats, and using them to populate search-result pages. In September 2010 Google announced their intention to surface hCard, hReview information in their local search results. In February 2011, Facebook began using hCard to mark up event venues.

Sidebar (computing)
The sidebar is a graphical control element that displays various forms of information to the right or left side of an application window or operating system desktop. Examples of the sidebar can be seen in the Opera web browser, Apache OpenOffice, LibreOffice, SoftMaker Presentations and File Explorer; in each case, the app exposes various functionalities via the sidebar. Overview Sidebars have originated in desktop apps, which are designed for rectangular screens with longer horizontal sides. Like toolbars and status bars, sidebars host both information and GUI widgets with which the user issues commands to the app. Unlike toolbars and status bars, sidebars have larger surface areas because of horizontally longer layout of desktop apps. Sidebars may use accordions to organize widgets and accommodate a larger layout than the visible surface area. Widgets In a number of Widget engines, one is able to install applets which can reside on a sidebar. Notable examples include: * Wi ...

Status Bar
A status bar is a graphical control element which poses an information area typically found at the window's bottom. It can be divided into sections to group information. Its job is primarily to display information about the current state of its window, although some status bars have extra functionality. For example, many web browsers have clickable sections that pop up a display of security or privacy information. A status bar can also be text-based, primarily in console-based applications, in which case it is usually the last row in an 80x25 text mode configuration, leaving the top 24 rows for application data. Usually the status bar (called a ''status line'' in this context) displays the current state of the application, as well as helpful keyboard shortcuts. One example is the 'vi' text editor of UNIX (from the 1970s) or newer Linux systems. Status lines have been used for more than 30 years to display advisory messages in a predefined area, rather than as pop-up messages in ...

Great Barr
Great Barr is now a large and loosely defined area to the north-west of Birmingham, England. The area was historically in Staffordshire, and the parts now in Birmingham were once known as Perry Barr, which is still the name of an adjacent Birmingham district. Other areas known as Great Barr are in the Metropolitan Boroughs of Walsall and Sandwell. "Barr" means "hill", and the name refers to nearby Barr Beacon. History Samuel Taylor, an itinerant Methodist preacher, visited Great Barr in 1792 and remarked "preached at Barr, a village famous for nothing as having given birth to Francis Asbury of America and being the present residence of his parents, at whose house we preached". Great Barr was largely rural until the early 20th century, though it was influenced by the early stages of the industrial revolution which affected the nearby towns of Birmingham and the Black Country. The Staffordshire parish of Barr straddled the route from Birmingham to Walsall. Birmingham's hist ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Toolbar
The toolbar, also called a bar or standard toolbar (originally known as ribbon) is a graphical control element on which on-screen icons can be used. A toolbar often allows for quick access to functions that are commonly used in the program. Some examples of functions a toolbar might have are open file, save, and change font. Toolbars are usually distinguished from palettes by their integration into the edges of the screen or of other windows. This can result in wasted space if multiple underpopulated bars are stacked atop each other or interface inefficiency if overloaded bars are placed on small windows. Variants There are several user interface elements derived from toolbars: * An address bar, location bar or URL bar is a toolbar that mainly consists of a text box. It typically accepts URLs or file system addresses. They are found in web browsers and file managers. * A breadcrumb or breadcrumb trail allows users to keep track of their locations within a program or a file sys ...
