Trident Project Managing an Extensible Digital Repository

This project discusses the development of Trident, an extensible digital repository at Duke University. It covers the scaling up process, organization, Apache Solr search server, cross-searching of collections, integration with other platforms, and the future plans for mass digitization and more multimedia content. The project aims to create a robust and extensible repository with a scalable metadata tool that can be reused with any schema.
