Zhuge’s paper describes the resource space model (RSM), a component of the Semantic Grid VEGA-KG system for managing Web resources that has a number of characteristics in common with the relational database model.

The RSM consists of three schemas: a user-view schema that functions as a browser for the user’s view of the resource space, a logical-level schema that provides a universal view, and a semantic Web view schema that is a “semantic-based representation and organization mechanism” for the resource space. Zhuge provides a formal description of the RSM by defining terms such as “resource space,” and the normal forms of a resource space, in addition to operations, such as a join, that can be applied to such spaces. Through resource analysis, a designer can specify all the resources that make up a given resource space, using a resource dictionary, store those resources, and later edit them. Designers may also partition a resource space into different domains. In one of several interesting sample applications presented in this paper, Zhuge describes the use of this approach to define the Association for Computing Machinery (ACM) Computing Classification System (which is Hypertext Markup Language (HTML)-based), using a normalized information space based on the RSM. Researchers working in the area of organizing various kinds of resources on the Web should find this paper interesting.
