But it is a critical handicap to exploit networks information resources and quickly and exactly obtain the required information from the huge bank. Therefore how to share the network information resource becomes a research hot-spot.Based on ontology theory of agricultures characters and combined with the knowledge of soil and agricultural chemistry, a web system was made for the soil knowledge system with native XML(extensible Markup Language)Database-Tamino as information navigation. This system could display relevant information in a tree structure and understand users demands.更多还原
