Fixing the 'Broken Link' Problem: The W3Objects Approach

摘要

This paper presents a model for the provision of referential integrity for Webresources which supports resource migration and tolerates site and communication failures. The approach is object-oriented, highly flexible, completely distributed, and does not require any global administration. An attractive feature of the authors' design is the provision of a lightweight mechanism which provides referential integrity, and which may be customized on per resource basis to provide increased fault-tolerance and performance. The authors' system follows an evolutionary approach, supporting parallel operation with the existing Web, allowing users to gain the additional benefits of referential integrity while allowing continued access through trusted software components.
