(3) Open Software description format OSD

Similar to the fate of EDI, the internet distribution of software packages has been in the pilot phase. The OSD (Open Software descriptipon) is a set of tags used in XML to describe a variety of software products, detailing software specifications, usage instructions, and operational platforms.

(4) Channel Definition format CDF

A Channel Definition format CDF (Channel definition Format) is the XML data format used by Microsoft in IE 4.0 browsers to describe the contents and desktop parts of the active channel, indicating the information of the channel and its update. The CDF makes it possible for different platforms to interoperate, enabling web publishers to control push technology. Dedicated push technology will no longer affect the interoperability of different push technologies, so that the same Web content can be obtained from incompatible platforms.

(5) Open Financial Exchange OFX

OFX (Open Financial Exchange) is also a set of tags for XML that describes the business dealings between accounting firms and customers. Using OFX, customers and accounting firms can exchange financial data directly, including documentation such as electronic banking and payment agreements.

To facilitate the use of XML, the consortium has approved the XML Standard 1.0 version, believing in XML 1? 0 of the promulgation will lead to a large number of advanced Web applications, users must start from now to consider the use of XML to write Web pages. But the massive use of XML does not mean that HTML will soon die. The forces of habit are powerful, just as the COBOL language has not exited the stage of history for a long time, and since a large number of existing Web pages are written in HTML, HTML will never be easily withdrawn from use. It can be expected that over the next 5 years, XML will work together with HTML in different areas of the Web application.
