1. The one essential tool for reading and modifying XML is a “parser”. The term “parser” and “processor” are interchangeably, although technically this is not correct. Any program that takes an XML file as its input and produces some output based on the XML files content is an XML processor. An XML browser is an example of processor, as are programs that create typesetting codes, synthesized speech or HTML pages based on XML document. A parser is software that performs the first step in processing an XML document. Seldomly, if ever, will an XML parsers operate on it’s own. Rather, a parser is almost always used as part of an XML processor. The most basic task of a parser is checking the XML document for well-formed data, making sure the documents content follows the rules of XML syntax. All parsers perform this task, if the syntax is incorrect the parser will detect it. Most parsers can also check a document for validity by checking against DTD or Schema. While not all documents require validation, many do. (Gokul, 2003)
2. W3C XML Schema which supports the transfer of benefits enrollment data between organizations. This schema is part of the XML Consortium effort to define an XML vocabulary to support business transactions. XML provides many benefits to adopters. The richness, flexibility and accessibility of the XML standard have made for early and enthusiastic adoption by many IT functions. As a result, there are a large number of tools available to help reduce the development effort associated with producing or processing data transmitted in XML. This reduces barriers to adoption of the standard for organizations of any size.(HR-XML, 2001)
3.Synchronized Multimedia Integration Language(SMIL) fulfills the needs of integration,synchronization, and efficient online delivery of differentmedia types such as text, music, speech, image, and video. It is a multimedia elements in a synchronized manner under a unified feature space. An efficient SMIL retrieval scheme based on textual feature and content feature is proposed. SMIL is suitable for real-time multimedia information delivery over networks,especially for limited bandwidth connections. As an example, the Multimedia Messaging Service (MMS) of mobile technology uses SMIL to represent messages. (IEEE, 2004)
