Abstract—With the development of information and digital technology, various information resources will be more, and growth exponentially. However, currently information resources construction generally has some problems, the main problem is that the effective sharing of resources is not shaped. Registration and discovery of information resources is the core and basis of resources effective sharing. Only on the basis of resources registration and discovery, other applications can be realized. This paper firstly proposes an improved metadata description of information resource. Based on the existing discovery mechanisms, present the model of information resource classified register and discovery based on hierarchy in grid, classified register center is a key of this model, we give a full account of classification method of classified registry center, and gives the algorithm. We describe the process of registration and discovery of information resources, and gives the algorithm, and tested this algorithm using the GridSim simulation , the test results show that: total simulation time of resource classification registration based on hierarchy the paper proposed is much lower than the GridSim built-in scheduling algorithm (Optimis Cost and Time ) in the same case, and with Gridlets increases, the time cost of algorithm the paper proposed is growing gently, Compared to the GridSim built-in scheduling algorithm (Optimis Cost and Time ),it has more advantages of time cost .
