State news standard research and application system design

In this paper, we have described the structural characteristics and other features of the news standards-Chinese News Information Markup Language (CNML), and compared with other news standards, highlight its advantage in the structure and application. According to the structure characteristics of CNML standard, we have designed a news release system based on B/S development mode. On the server side we apply JAXB technology to achieve mapping between CNML document and relational database. On the client side, using Ajax technology belonging to Web2.0, we have realized asynchronously accessing to news data from the server, and at the same time effectively saving the communication bandwidth. JQuery framework has realized all methods for Ajax. Using the JSON format for transmitting data can further improve the efficiency of news content parsing.
