A scalable model of distribution promoting autonomy of and cooperation between PJava object stores

Distributed persistent systems often provide transparency of distribution at the cost of autonomy of object stores, efficiency of cooperation between them and scalability of the system. We propose a flexible model of distribution to support scalable persistent application systems that allows for both autonomous stores with low cost limited commitments to other stores and sophisticated models of interaction on a limited scale with maintainable inter store references. Scalability would be provided by exposing the distribution of stores, with the use of extended URLs as global names. Autonomy of a store would be preserved by making it possible for the store to retain control over the objects it makes available for remote use
