The document discusses the evolution of library metadata standards from MARC to Linked Data frameworks like BIBFRAME. It argues that the focus should not just be on the end goal of fully implementing BIBFRAME, but on the important work of preparing existing legacy data to integrate semantic concepts and building the underlying linked data infrastructure that is necessary to realize the benefits of models like BIBFRAME. Specifically, it encourages libraries to begin enriching MARC records with semantic data and to work with national libraries and partners to develop the networks and relationships of trust between data that will support future metadata environments.
