Uni-grid P&T: A toolkit for building customizable grid portals

This paper presents an architecture and functional design of Uni-Grid P&T, a toolkit for building customizable Grid portals for different application domains in a typical university environment in China. Based on a layered architecture, the functions of the toolkit are designed on top of the new Open Grid Services Architecture (OGSA) and based on the standards of Web services. We particularly address the issues of collaborative portals and portlet implementations of the toolkit. The development of the toolkit is part of the initiative of the ChinaGrid project launched in 2002 by the Ministry of Education of China that is aimed to build a China national education Grid to link more than 100 major universities across China.
