21 content management
E-comthe means and methods of managing the textual and graphical content of a Web site. For large sites with thousands of pages and many interchangeable words and images, it pays to invest in a content management application system that facilitates the creation and organization of Web content. Some content management systems also offer caching (where a server stores frequently requested information) and analysis of site traffic.Recent years have seen a vast growth in the quantity of content produced by organizations, particularly in digital form. In 2001, it was estimated that there were over 550 billion documents on Internet, intranet, and extranet websites—making professional content management vital. Without it, it becomes almost impossible for a user to find the information they are looking for.However, excellent content management is expensive, and organizations need to establish a solid business case in order to justify it. The initial point for consideration is that content is not a low-level commodity that merely needs to be stored—it is a critical resource, and its value lies in it being read. So an understanding of who will read it is essential. Decisions need to be taken over what languages the material needs to be published in, and in what media (Web or e-mail, for example). The form of the content—text, audio, video—is also important, as is the sensitivity of the material and the consequent security required.Simply storing content is data management, but content management should have publication as its main focus, with the intention of informing or entertaining readers. There is a big difference in approach between the two. -
22 Jenkins, Charles Francis
[br]b. 1867 USAd. 1934 USA[br]American pioneer of motion pictures and television.[br]During the early years of the motion picture industry, Jenkins made many innovations, including the development in 1894 of his own projector, the "Phantoscope", which was widely used for a number of years. In the same year he also suggested the possibility of electrically transmitting pictures over a distance, an interest that led to a lifetime of experimentation. As a result of his engineering contributions to the practical realization of moving pictures, in 1915 the National Motion Picture Board of Trade asked him to chair a committee charged with establishing technical standards for the industry. This in turn led to his proposing the creation of a professional society for those engineers in the industry, and the following year the Society of Motion Picture Engineers (later to become the Society of Motion Picture and Television Engineers) was formed, with Jenkins as its first President. Soon after this he began experiments with mechanical television, using both the Nipkow hole-spiral disc and a low-definition system of his own, based on rotating bevelled glass discs (his so-called "prismatic rings") and alkali-metal photocells. In the 1920s he gave many demonstrations of mechanical television, including a cable transmission of a crude silhouette of President Harding from Washington, DC, to Philadelphia in 1923 and a radio broadcast from Washington in 1928. The following year he formed the Jenkins Television Company to make television transmitters and receivers, but it soon went into debt and was acquired by the de Forest Company, from whom RCA later purchased the patents.[br]Principal Honours and DistinctionsFirst President, Society of Motion Picture Engineers 1916.Bibliography1923, "Radio photographs, radio movies and radio vision", Transactions of the Society of Motion Picture Engineers 16:78.1923, "Recent progress in the transmission of motion pictures by radio", Transactions ofthe Society of Motion Picture Engineers 17:81.1925, "Radio movies", Transactions of the Society of Motion Picture Engineers 21:7. 1930, "Television systems", Journal of the Society of Motion Picture Engineers 15:445. 1925.
