In 1998, the International Federation of Library Associations introduced a new model for library catalog data, focusing on the bibliographic relationships within metadata. This model, known as the Library Reference Model (LRM), includes four main elements: Work, Expression, Manifestation, and Item (WEMI), each representing different aspects of created resources. To support the broader use of these WEMI concepts, OpenWEMI was developed by the Dublin Core Metadata Initiative, providing a general vocabulary with minimal constraints. OpenWEMI’s RDF vocabulary includes classes and properties designed to facilitate the creation of context-specific metadata vocabularies, allowing for the flexible integration of WEMI concepts in diverse applications.
