Abstract
Abstract A memory for storing data for access by an application program being executed in a processing system of a distributed computing environment includes an object-oriented data structure. The data structure include a plurality of base data objects having predetermined instances including a directory object and an entry object, and a plurality of attribute data objects storing information about particular resources. The plurality of base and attribute data objects are configurable into a namespace, e.g., a tree structure, that enables the application program to locate resources in the distributed computing environment. The predetermined instances of the base data objects may also include a link object that points to another object in the tree structure, thereby transforming the namespace into a directed graph.
