VI, XML Prospect
The production of any new technology background, their needs are all, XML is the birth of HTML experience can not be overcome later.HTML in recent years, many complex problems encountered in Web applications, to solve these problems, we must use powerful XML Web pages instead of HTML as a writing tool.XML is conducive to the expression and structure of information organization, so that the data searches more effective; XML can use URL aliases to make maintenance more convenient Web, but also to make Web applications more stable; XML digital signatures can be used to develop a broader application of Webto the security field.That the future of Web writing instrument must be XML.The extensive use of XML Web must be able to promote the development, thus creating a new era of Web applications.
Web applications will use XML, as more exciting, here are several predictable application of XML.
(1) XML / EDI Electronic Data Interchange
EDI (Electronic Data Interchange) is the use of electronic technology to replace paper-based means of operation for the exchange of documents between companies.XML format of the rich language used to describe different types of documents, such as letters of credit, loan application, insurance, claim form and various invoices.Structured data in XML documents sent to the Web can be encrypted, and easily attach digital signature.XML, EDI security measures can fully demonstrate the application of its charm, XML promising large-scale promotion of EDI applications.
(2) Chemical Markup Language CML and the Mathematical Markup Language Math ML
CML (chamical Markup Language) and the Math ML (Mathematical Markup Language) is the XML description of the chemical and mathematical formulas used in the markup language.CML can describe the molecular and crystal structure of the spectral structure of compounds.The Math ML is a mathematician of the Gospel, since the Web's inception, mathematicians can use the Math ML first mathematical formula to accurately displayed in the browser.
(3) OSD Open Software Description format
And the similar fate of EDI, Internet distribution package has been in pilot phase.OSD (Open Software Descriptipon) is a set of XML software products used to describe a variety of tag set, you can specify the software specifications, instructions, and can run platforms.
(4) Channel Definition Format CDF
Channel Definition Format CDF (Channel definition format) is Microsoft IE 4.0 browser in the XML data format used for describing the content of active channels and desktop components, specify the channel information and updates.CDF to make the interoperability of different platforms as possible, so that Web publishers can control the push (push) technology.Dedicated Push Push Technology will no longer affect the interoperability of different, so that, from incompatible platforms can achieve the same Web content.
(5) Open Financial Exchange OFX
OFX (Open Financial Exchange) is an XML tag set, used to describe the accounting firm's business dealings with customers.Using OFX, customers and accounting firms can be directly exchanged between the financial data, including electronic banking and payment agreements documentation.
In order to promote the use of XML, W3C XML standard has been ratified version 1.0, I believe that XML 1? 0 will lead to the promulgation of a large number of advanced Web applications, users must start thinking from now on to write Web pages using XML.However, the extensive use of XML does not mean that HTML will immediately die.The forces of habit is strong, as Cobol language in a very long period of time, the stage of history not as large as the existing Web pages are written using HTML, HTML will not be easily withdrawn from use.Can be expected in the next 5 years, XML will work side by side HTML Web applications in common use in different areas.
