Title A name given to the resource Research Paper-Library science Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections. For more information see, http://dublincore.org/documents/dces/. Title A name given to the resource Semantic Mapping of Bibliographic Models in National Libraries⋆ Subject The topic of the resource Library and information science Description An account of the resource This paper presents a comparative analysis of the data and metadata models used by national libraries that publish their collections following the principles of Linked Open Data (LOD). Using the Crosswalk method, the study mapped the classes and properties adopted by different institutions, identifying conceptual convergences, terminological variations, and distinct modeling strategies. The results reveal heterogeneous practices, ranging from simplified models to robust, ontology-based structures. Despite shared core entities such as Work and Person, semantic differences remain regarding the scope and level of detail. The findings support the development of semantic alignment strategies and shared vocabularies to improve interoperability.
