Technology under developing
Grid Entity (GE)
A suit of local middle ware and tools to deploy, manage, monitor providers’ resources in form of services.
Engineering levelGrid Entity is not the basic grid componentGrid Entity is used for the assembling of grid resources
(web-services) within one institute. Grid Entity is implemented with the form of WPS
container and toolkits
There are three GEs in SIGP-N : Processing Grid Entity NodeD-N : Data service Grid Entity NodeM-N : Mapping Grid Entity Node

For developer, they can use GE framework toquickly package their classes (C++, JAVA) simply assemble other web-service into grid
system easily manage (registry and publish ) all their
web-services on grid levelfully support the WCS, WFS and WPS compatible
