Information: - In computing, Extensible Markup Language (XML) is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. The W3C's XML 1.0 Specification and several other related specificationsall of them free open standardsdefine XML. - Query languages are computer languages used to make queries in databases and information systems. - The World Wide Web Consortium (W3C) is the main international standards organization for the World Wide Web (abbreviated WWW or W3). - XPath 2.0 is a version of the XPath language defined by the World Wide Web Consortium , W3C . It became a recommendation on 23 January 2007 . As a W3C Recommendation it was superseded by XPath 3.0 on 10 April 2014 . XPath is used primarily for selecting parts of an XML document . For this purpose the XML document is modelled as a tree of nodes . XPath allows nodes to be selected by means of a hierarchic navigation path through the document tree . The language is significantly larger than its predecessor , XPath 1.0 , and some of the basic concepts such as the data model and type system have changed . The two language versions are therefore described in separate articles . XPath 2.0 is used as a sublanguage of XSLT 2.0 , and it is also a subset of XQuery 1.0 . All three languages share the same data model ( the XDM ) , type system , and function library , and were developed together and published on the same day . - A standards organization, standards body, standards developing organization (SDO), or standards setting organization (SSO) is an organization whose primary activities are developing, coordinating, promulgating, revising, amending, reissuing, interpreting, or otherwise producing technical standards that are intended to address the needs of a group of affected adopters. - XPath (XML Path Language) is a query language for selecting nodes from an XML document. In addition, XPath may be used to compute values (e.g., strings, numbers, or Boolean values) from the content of an XML document. XPath was defined by the World Wide Web Consortium (W3C). - The World Wide Web (abbreviated WWW or the Web) is an information space where documents and other web resources are identified by Uniform Resource Locators (URLs), interlinked by hypertext links, and can be accessed via the Internet. English scientist Tim Berners-Lee invented the World Wide Web in 1989. He wrote the first web browser computer program in 1990 while employed at CERN in Switzerland.

Q: Information: - In physics, an orbit is the gravitationally curved path of an object around a point in space, for example the orbit of a planet about a star or a natural satellite around a planet. Normally, orbit refers to a regularly repeating path around a body, although it may occasionally be used for a non recurring trajectory or a path around a point in space. To a close approximation, planets and satellites follow elliptical orbits, with the central mass being orbited at a focal point of the ellipse, as described by Kepler's laws of planetary motion. - 793 Arizona is a minor planet orbiting the Sun that was discovered in 1907 by American businessman Percival Lowell . It was named for the state of Arizona . Photometric observations at the Palmer Divide Observatory in Colorado Springs , Colorado during the winter of 2007 -- 2008 were used to build a light curve for this asteroid . The asteroid displayed a period of 7.367 0.005 hours and a brightness change of 0.25 0.02 in magnitude . - Lowell Observatory is an astronomical observatory in Flagstaff, Arizona, United States. Lowell Observatory was established in 1894, placing it among the oldest observatories in the United States, and was designated a National Historic Landmark in 1965. In 2011, the Observatory was named one of "The World's 100 Most Important Places" by TIME. It was at the Lowell Observatory that the dwarf planet Pluto was discovered in 1930 by Clyde Tombaugh. - A minor planet is an astronomical object in direct orbit around the Sun that is neither a planet nor exclusively classified as a comet. Minor planets can be dwarf planets, asteroids, trojans, centaurs, Kuiper belt objects, and other trans-Neptunian objects. As of 2016, the orbits of 709,706 minor planets were archived at the Minor Planet Center, 469,275 of which had received permanent numbers ). - Percival Lawrence Lowell (March 13, 1855 November 12, 1916) was an American businessman, author, mathematician, and astronomer who fueled speculation that there were canals on Mars. He founded the Lowell Observatory in Flagstaff, Arizona and formed the beginning of the effort that led to the discovery of Pluto 14 years after his death. - The Minor Planet Center (MPC) is the official worldwide organization in charge of collecting observational data for minor planets (such as asteroids) and comets, calculating their orbits and publishing this information via the "Minor Planet Circulars". Under the auspices of the International Astronomical Union, it operates at the Smithsonian Astrophysical Observatory, which is part of the Center for Astrophysics along with the Harvard College Observatory.
