Towards the Schema Heterogeneity in Distributed Digital Libraries

In this paper, we discussed the problems brought by the schema heterogeneity in DLs, especially those problems found in the application of the OAI-PMH protocol. This paper studies the problem from two perspectives, namely the schema and the architecture respectively. A preliminary architecture is provided that integrates the ontology, agent, P2P together to support the schema mapping. And the semantic negotiation strategy between the heterogenous agents has also been described.
