Abstract: In grid,resource registry meta-service assumes the responsibility for the registery,management and indexing of resources in grid. It's very important for the running of grid. In this paper,we put forward a resource specification language and provided its reference by XML Schema first. Then,we designed the distributed resource registry meta-service and implemented it based on Java language. It has been used in digital forestry grid and provided stable and high-performance services for resource registering and searching.
