Library Reference Model (LRM) as a new conceptual model for constructing linked data in library has impact on RDA as content rules and BIBFRAME as encoding format. Among LRM attributes (or properties), especially, representative expression is a new one. RDA has expanded the attributes to reflect representative expression of LRM, BIBFRAME should also accept the RDA elements for representative expression because BIBFRAME should reflect RDA attributes as encoding format. This poster is to propose the BIBFRAME mapping with RDA representative expression.
