The Object Oriented Document Model of a Meta System for Existing Digital Libraries

In this paper we describe an object oriented document model of a meta system for existing digital library systems. We show how we solve heterogenity of existing systems in the context of linking and annotating existing digital library documents with a slim and simple approach. Our approach is already implemented in the system OMNIS/2, which is an advanced meta system for existing digital library systems and enhances existing digital library systems or retrieval systems by additional storing and indexing of user-defined multimedia documents, automatic and personal linking concepts, annotations, filtering and personalisation.
