A text-centric markup derived from SGML (Standard Generalized Markup Language), XML (Extensible Markup Language) helps define protocol for encoding documents in a way that can be understood by both humans and machines. XML tags are different from HTML tags ? the former is prominently used for data identification, organization, and storage, while the latter is mostly used for data display. XML seems to be much superior in a way that it boasts of a lot of HTML features, but has its own unique functionality as well.
Software personnel prefer XML for three of its important characteristics ? to begin with, XML does not participate in displaying data, it basically carries the data. In essence, it allows users to store data no matter how it will be presented. Secondly, as the name suggests, it is an extensible markup; it enables programmers to create their own tags which they find suitable to their applications. And lastly, XML is available as an open standard.
One of the main advantages of XML that companies leverage is content reuse. It helps realize time and cost savings as information us handles less often and content editing and updating is done just once for many documents.
What is XML Authoring?
Since long, desktop publishing has been used to maneuver data in technical publications; indeed, since it was introduced over three decades earlier, it has been the go-to paradigm for content creation. It is characterized by tools that have rich and powerful features, easy template overrides, and the WYSIWYG (What You See Is What You Get) feature, where authors can exactly see the final version of how the document will look, as they are working on it. In addition, authors have style guidelines and templates, although they have the option to not follow them as well.
XML authoring is a new and enhanced version of technical communication, which is quite an improvement over desktop publishing. For one thing, it works on the WYSIOO (What You See Is One Option) model; that is, the content is displayed with a little bit of formatting, however, it is not how the final document will look. To view the same, a separate process is required to be carried out. Also, unlike desktop publishing, XML authoring mandates template compliance ? the authoring tool itself enforces templates, and authors are expected to adhere to the structure standards of the software in question.
In XML authoring, content generation and publication are separate; meaning, authors will not be able to do much to improve the appearance of the final deliverable. Despite the fact that desktop publishing boasts of better features, XML authoring is gaining traction, as it offers benefits such as better information, better content storage, cost reduction, and automated formatting.
