Only as a web pages search system, DRIS will download and index all the web pages in three levels domain and provide standard search interface in every node. The data format for input and output of this interface is standard XML but not HTML. DRIS is not a final search engine, but provide the data source for other personal intelligent system, which is designed by your interest and knowledge background. XML may be the best data format for most application system. You can consider DRIS is a mechanism that arranges all HTML source to XML source. Certainly, the XML data in DIRS can comply with the W3C's seven levels'semantic module, which will give great help to design the intelligent search systems. But now, there still no a system that can understand you query "which actors played in movies after books written by authors born in Chili in 1961?" very well and give you a precise answer. So DRIS just builds the information retrieval infrastructure for Internet, other work will be left to AI experts.
