Hypertext

On the one hand and according to the Webpage http://www.w3.org/ and the scientist Ted Nelson, the meaning of  Hypertext (a concept, not a product) is a text which contains links and isn’t constrained to be clear. However, Wikipedia says that the Hypertext text on a computer that will lead the user to other, related information on demand. Hypertext is a representation of  a relative recent innovation to user interfaces.

On the other hand,Roland Barthes points out that the hypertext is an ideal text that precisely matches. As I said before, it consist on a text composed of an amount of words or images linked electronically. They are also perpetually unfinished.

Hypertext is a text that branches and allows choices to the reader, such as the possibility of taking differet pathways to read the text the reader wants to. Hypertext also denotes a medium information, which links verbal and non – verbal information.

XML

XML is an initialism of Estensible Markup Language. This is a general purpose specification for creating personalized markup languages. It’s clasified as extensible language; it allows everyone to define the mark – up elements. XML a simple and a very flexible text format which derives from SGML and it was originally designed to to meet the challenges of large-scale electronic publishing. The objective is to help information systems in sharing and exchanging structured data, especially via the Internet, to encode documents, and to serialize data; in the last context, it compares serialization languages, which are based on texts, such as JSON and YAML.

Extensible Markup Language is highly recommended by the World Wide Web Consortium (W3C). It is a fee open standard. This recommendation tells us and specifies lexical grammar and parsing requirements.
To conclude, we can say that XML began as a simple subset of the SGML.

    HTML

    According to Wikipedia, the meaning of HTML is HyperText Markup Language. It is the predominant markup language of Web pages.  It provides a means to describe the structure of text – based information in a document (by denoting certain text as links, headings, paragraphs, lists, and so on) and to supplement that text with interactive forms, images, and a large number of different kinds of objects. HTML is written in the form of tags, surrounded by angle brackets. HTML can also describe, to some degree, the appearance and semantics of a document, and can include embedded scripting language code, for exmple, JavaScript, which can affect the behavior of Web browsers and other HTML processors.

    The HTML is one of the most well-known examples of a markup language in the use of nowadays. The HyperText Markup Language (HTML) is also one of the most used language in the World Wide Web. HTML follows some of the markup conventions used in the industry of publicity in the communication of essays and work which are printed among authors, editors, and printers.

    Another definition of HTML, in these case according to the webpage W3C, is that HTML is called lingua franca for publishing hypertext on the WWW. It is a non – proprietary format based upon SGML, and it can be created and processed by a wide range of tools, from simple plain text writers and printers.
