Abstract

Interoperability between digital libraries depends on effective sharing of metadata. Successful sharing of metadata requires common standards for metadata exchange. Previous efforts have focused on either defining a single metadata standard, such as Dublin Core, or building digital library middleware, such as Z39.50 or Stanford's Digital Library Interoperability Protocol. In this article, we propose a distributed architecture for managing metadata and metadata schema. Instead of normalizing all metadata and schema to a single format, we have focused on building a middleware framework that tolerates heterogeneity. By providing facilities for typing and dynamic conversion of metadata, our system permits continual introduction of new forms of metadata with minimal impact on compatibility.
