XML

XML es un Lenguaje de Etiquetado Extensible muy simple, pero estricto que juega un papel fundamental en el intercambio de una gran variedad de datos. Es un lenguaje muy similar a HTML pero su función principal es describir datos y no mostrarlos como es el caso de HTML. XML es un formato que permite la lectura de datos a través de diferentes aplicaciones.Las tecnologías XML son un conjunto de módulos que ofrecen servicios útiles a las demandas más frecuentes por parte de los usuarios. XML sirve para estructurar, almacenar e intercambiar información. XMLfunciona como un lenguaje avanzado para crear hojas de estilos. Es   capaz de transformar, ordenar y filtrar datos XML, y darles formato basándolo en sus valores.   http://www.w3c.es/divulgacion/guiasbreves/tecnologiasXML   Enero 20, 2008

orality and literacy

  Ong’s most widely known work, Orality and Literacy: The Technologizing of the Word (1982), a volume in the New Accents Series, is translated into eleven other languages. In it he attempts to identify the distinguishing characteristics of orality: thought and its verbal expression in societies where the technologies of literacy (especially writing and print) are unfamiliar to most of the population. He then reviews the transition from an oral culture to awriting culture, that is to the use of the technologies of written words for communication.Ong drew heavily on the work of Eric A. Havelock who suggested a fundamental shift in the form of thought coinciding with the transition from orality to literacy in Ancient Greece. Ong describes writing as a technology that must be laboriously learned, and which effects the first transformation of human thought from the world of sound to the world of sight. This transition has implications for structuralism, deconstruction , speech-act and reader-response theory, the teaching of reading and writing skills to males and females, social studies,biblical studies, philosophy, and cultural history generally.

XML

What is XML? XML is the standard Extensible Markup Language. XML is a metalanguage that defines the syntax used to define other languages labels structured. Its purpose is to help the sharing of information from different systems.

Objectives XML was created under the World Wide Web Consortium (W3C) body which ensures the development of WWW based on the broad specifications of SGML. Its development began in 1996 and the first version came to light on February 10, 1998. The first definition that appeared was: System to define and validate sharing document formats on the Web. During the year 1998 XML grew exponentially, and by that I mean their appeared in media, mentions on web pages, support software, and so on. With regard to its objectives are: * XML must be compatible with SGML. * It should be easy to write programs that process XML documents. * The number of optional features in XML must be minimum, ideally zero.

Advantages The XML pretends to be more suitable for the browsers and easier to use than the HTML, which has always cause problems. The main advantages that the XML language includes are:

– It’s performance is simple and compatible with much aplications.

– Allows you using different languages at the same time.

– You can be sure that you are not having sintaxic errors.

The importances and consequences As IBM Systems Journal says XML has become the predominant mechanism for electronic data interchange between information systems and can be described as a universally applicable, durable “Code of Integration.” As we celebrate its tenth anniversary, it is appropriate to reflect on the role XML has played and the technical ecosystem in which it functions. In this paper, we discuss both the environment from which XML arose and its technical underpinnings, and we relate these topics to companion papers in this issue of the IBM Systems Journal. We discuss the broad consequences of XML and argue that XML will take its place among the technical standards having the greatest impact on the world in which we live. We conclude with some reflections on the significant technical, economic, and societal consequences that XML is likely to have in the future.
