The Bibliographic Conceptual Models Interest Group convened on Wednesday, March 5 2025 at 3 PM CT for a presentation on use of a Reference Ontology (RO) to address semantic misalignments between the BIBFRAME and RDA/LRM ontologies. Use of a reference ontology for semantic mediation is distinct from creation of a metadata application profile and from transformative techniques such as metadata crosswalks. The presentation featured examples of using a reference ontology to query bibliographic datasets.
Presenter Helena Patrício is a Research Assistant at the Information Sciences, Technologies and Architecture Research Centre (ISTAR-Iscte) of the University Institute of Lisbon, and works as librarian at the Information and Documentation Center of the Portuguese Film Archive and Museum. She was Director of Special Collections Services at the National Library of Portugal from 2012 to 2024, during which time she was responsible for the National Digital Library. She holds a master's degree in Information Studies and Digital Libraries, and is currently a PhD student with research interests in the semantic web and linked open data.
