Abstract:

This paper presents 'Distributed Active Relationships' (an extension of the Warwick Framework), a general framework for dealing with meta data issues in digital libraries and other information systems. By treating meta data as data, rather than giving it a special distinguished role, arbitrary resources are allowed to be associated with arbitrary relationships.
