Digital media service oriented digital museum Grid

In this paper we design and implement a digital media service oriented digital museum platform based on Grid. We construct the whole system based on the Open Grid Service Architecture (OGSA), which supports flexibly constructing and deploying various digital media applications. The system shield the heterogeneity of resources via data access service so that the enormous dispersed resources can be effectively accessed and integrated. We also propose an on-demand application constructing method based on service composition. Using this method, we can implement digital media applications by dynamic service binding. Moreover, we implement digital media service applications based on this platform, such as 3D virtual museum walkthrough system.
