Method, system, and computer program product for providing an extensible file system for accessing a foreign file system from a local data processing system

6988101

Abstract

An extensible file access method for accessing a first foreign file system from a data processing system with a first native file system, said first foreign file system and said first native file system implementing different file system protocols. The foreign file system is accessed by issuing a request according to the native file system protocol for data stored in the foreign file system; translating the native file system request to an intermediate programming interface, wherein the intermediate programming interface is different from both the native file system protocol and the foreign file system protocol; translating the intermediate file system request to the foreign file system protocol; and returning to the client a response from the foreign file system responsive to the translated request.
