This document summarizes and evaluates the changes between Bibframe 1.0 and Bibframe 2.0 for representing bibliographic metadata. Bibframe 2.0 addresses some critiques of the original model by consolidating classes and simplifying the vocabulary structure. The document analyzes how these changes affected the mapping of MARC records to Bibframe and compares the representation of FRBR entities between the two versions. Overall, the document aims to determine if Bibframe 2.0 offers any benefits to bibliographic description over the previous model.

5. The Aim
• “How has Bibframe 2.0 changed from the first
iteration of Bibframe and what benefits, if any,
