In a global context which promotes the use of explicit semantics for sharing information and developing new services, the MAchine Readable Cataloguing (MARC) format that is commonly used by libraries worldwide has demonstrated its limitations. The semantic model for representing cultural items presented in the Functional Requirements for Bibliographic Records (FRBR) is expected to be a successor of MARC, and the complex transformation of MARC catalogs to FRBR catalogs (FRBRization) led to the proposition of various tools and approaches. However, these projects and the results they achieve are difficult to compare on a fair basis due to a lack of common datasets and appropriate metrics. Our contributions fill this gap by proposing the first public benchmark for the FRBRization process.
