MEF Multilingual Entity File

MEF is a linked entity hub that aggregates and aligns authority records from VIAF, IdRef, GND, and RERO. It provides a unified, stable identifier for persons, organisations, concepts, and places across multiple source systems — making multilingual metadata reuse seamless for integrated library systems and data pipelines. Records are harvested automatically and kept in sync with their upstream sources.
