The document discusses an evaluation of metadata usage and distribution in a linked data environment. It analyzes datasets from different institutions that mapped manuscript metadata to the Europeana Data Model (EDM) and a DM2E model. The evaluation aims to discover similarities and differences between datasets from different mapping institutions. It finds variations in usage of classes, properties, ontologies, and structural metrics like predicate-object-equality-ratio. The conclusion is that linked data quality assurance is important and people have a strong influence on metadata mapping.
