【Abstract】 ChIN is an Internet chemical resources navigator which mainly consists of HTML documents. ChIN’s maintenance relies heavily on the HTML editor at present, which has become more and more difficult for editors to keep ChIN up to date as the size of ChIN grows rapidly. A database based approach has been implemented for the new version of ChIN. This paper focuses on the design and implementation of web interactive modules between the ChIN database and users. The modules carry out the daily tasks to accept user submitted new resources and user’s comments or voting for a specific piece of resource into ChIN’s database. The modules are also responsible for the subscription and automated delivery of the e\|mail based ChIN Newsletter, for the integration of database searching and full\|text searching of ChIN. These web interactive modules will not only increase the accessibility and ease\|of\|use of ChIN, but also will enable users to contribute their knowledge and experiences to the content of ChIN and the selection of chemical resources for ChIN.更多还原
