Extracting, Augmenting, and Updating Metadata in Fedora 3 and 4 Using a Local OpenRefine Reconciliation Service

When developing local collections, librarians and archivists often create detailed metadata which then gets stored in collection-specific silos. At times, the metadata could be used to augment other collections but the software does not provide native support for object relationship update and augmentation. This article describes a project updating author metadata in one collection using a local reconciliation service generated from another collection's authority records. Because the Goddard Library is on the cusp of a migration from Fedora 3 to Fedora 4, this article addresses the challenges in updating Fedora 3 and ways Fedora 4's architecture will allow for easier updates.
