Lenguajes de marcas para la gestión de contenidos y la publicación Web (debate)

First and foremost, we would like to explain the terms involved. Being both markup languages, on  the  one  hand,  HTML  stands  for  “Hyper  Text Markup  Language”,  and  on  the  other,  XML stands for “Extensible Markup Language”.
 
Focusing on  the differences, XML points at  the  structure of  the  information, saving  time and simplifying  the  software,  not  requiring,  consequently,  DTD  or  Document  Type  Definition. Besides,  it supports Unicode, allowing almost any  information  in any written human  language
to be communicated, and in addition, it doesn’t have any data. HTML however, requires from the authors  to avoid  the use of presentational markup as well as  to  use available markup  to differentiate  the  meanings  of  phrases  and  structure  in  the  document.  Moreover,  HTML documents are more difficult to be delivered, as they are normally delivered either over HTTP servers or through e-mail.
 
In short, XML is more useful than HTML not only because it is easier to try for the computer programs, but also because HTML does not indicate what it is representing. In fact, HTML is known for describing the content of what it labels.

La oralidad y la escritura en los hipermedios (debate)

First of all, let us define the concepts involved. On the one hand, according to N.H. Nelson, the term hypermedia is used as an extension of the term hypertext, in which graphics, audio, video, plain text and hyperlinks are involved, being the World Wide Web the clearest example. On the other hand orality involves the capacity of speaking of each person as well as the gestures and other sources used.

According to experts on the subject, the hypermedia has changed the orality. As Perez Tornero mentions, due to the hypermedia we can send an oral message from one point of the planet to another, giving a kind of globalisation to the text and without realising how far the person receiving the message is. However, according to Brian and Williams, the hypermedia contributes to the worsening of the language as they, as well as networks, are opened to anybody. Besides, almost anything is accepted and owing to that, some writers transfer some of their bad acquired habits in writing from one media to another. Moreover, a big percentage of the users may write without any kind of information or taking it from poor sources.

Kevin Kelly (debate)

Kevin Kelly is an American writer, photographer and conservationist whose writings, despite dropping out of university after one year of studies, has acquired relevance being published in newspapers such as “The New York Times” or “The Economist“. So great has been his success that the well-known film Matrix was based on evidence from his book. We’ve decided to dedicate this article to Kelly due to his wide knowledge on the subject.

According to Kelly, the web has suffered a dramatic change. Whereas years ago, it used to be a green screen with cursors, connecting one computer with another, being known as the “net”, we’ve moved to a new stage now. This stage we are actually in, uses the idea of linking pages. Should I want to go to an airline web page, I will go from my page to FTP site. The evolution the web has suffered is exemplified by the 100 billion clicks done per day or the 2 million emails sent per second. Besides, in the year 2005, there were more than 100 web pages available per person alive. With regards to the future, the web is going to continue its development until it becomes part of us, becoming us at the same time part of it.

As a clear example of this development, we’ve got eBay, the famous portal to sell and buy objects. As Kelly mentions in his article “Ten years ago I heard sceptics swear nobody would ever buy a car on the Web”. Last year eBay Motors sold $11 billion worth of vehicles”.
