There are many resources which are existed in various forms and with different function in Internet. How make use of abundant resources and avoid producing information isolated island is the problem that people focuses on resolving all along time. So the grid technique emerges which objective is providing a valid approach for resource sharing. With the demand of the resource sharing and the resource cooperation increasing, the grid technique grows quickly. The grid resource management is the one of the core problems of grid research. Grid resource management makes up of resource discovery, resource allocation, resource location, resource monitoring, and resource renew and so on. In the middle of them, that resource discovery, resource allocation and resource location are implemented needs a foundation -- reasonable resource description. Resource discovery is the key problem which is used in resources share and resources cooperation. Therefore, this paper mainly focuses on the method about grid resource description and the mechanism of resource discovery.The paper firstly summarized the concept, progress and research fields about grid. Then we describe some the characteristics of resource in the grid resources management system. The grid resource management model and the grid resource management process are also discussed. A comparison is made between some resource management models and their limitations are summarized. Resource description methods and resource discovery mechanisms are important parts in this paper. According to the research, we suggest a model of grid resource register and resource discovery, called GRRDM. This paper makes following contributions:1.A grid resource description method based on classified metadata is suggested. It uses XML and RDF to establish a uniform metadata standard for each type of resource. XML can provide a kind of standard carrier which can be used in GRRDM exchanging data with external environment; and the uniform metadata standard can...
