Metadata switch

This initiative explores value-added services for metadata, emphasizing OCLC's strengths in cooperative processing. We aim to aggregate metadata for reuse and enhance collaboration within the Metadata and Cooperative Discovery Services. The discussion includes schema interoperability and making knowledge organization services more accessible. We focus on managing unique, non-published materials that support learning and cultural engagement. As digital initiatives grow, libraries must adapt to maintain relevance in information management for research and learning.
