This paper presents the process used to transition legacy Qualified Dublin Core metadata to Linked Open Data on a Hydra platform. We describe our use of property hierarchies included in RDF vocabularies to build interoperability into our data model. Our system utilizes an Open World approach, adopting an extensible model using metadata fields from many library and cross-domain schemas and flexibly integrating data from external sources. Our implementation supports automated cross-schema indexing and intelligent display and navigation of properties unknown to the software. These advancements expand on previous work on RDF in Hydra, allowing more robust integration with the broader Linked Data ecosystem. The work presented was completed as a part of the OregonDigital.org partnership, a collaboration between The University of Oregon Libraries and Oregon State University Libraries and Press that has operated a joint digital asset management system since 2009. OregonDigital.org holds diverse collections of digital archival materials from cultural heritage to faculty research collections.
