XML as a programming tool - Essay Example

Deriving an electronic representation of the paper documents would allow users to view them on a computer screen, take their printouts or store them in the database; however, to achieve this objective, standard forms for different document types and accompanying style sheets would be required. At present, still most of the exchange of information in the health care industry is carried out through printed documents that convey the information in two ways: the content of the document that contains the words, pictures and other information, and the format of the content that provides visual clues for font, font size and location (Sokolowski & Dudeck, 1999).

Recently, XML (eXtensible Markup Language), a subset of SGML (Standard Generalized Markup Language), has gained widespread popularity in the health care industry because it provides a mechanism to encode healthcare documents and their types into electronic form, and therefore, has led to the development of implementation recommendations in the form of a set of standard DTDs to standardize and match the electronic document requirements in the health care industry (Sokolowski & Dudeck, 1999). DTDs (Data Type Definitions) are crucial for health care informatics as they provide a facility for standardizing formats with style sheets, provide a document information model, provide context for narrative text, and allow for agreement on high-level structures.

They describe the structure of the document, the names of the allowable elements, the content of each element type, the structure of the document including the order in which the elements must appear (Sokolowski & Dudeck, 1999). The Darwin Information Typing Architecture (DITA) is designed to provide an XML framework for developing product documentation and has seen rapid adoption and implementation as compared to other approaches for purpose of
