In this presentation, the PCC Sinopia Cataloging Affinity Group will share updates to the Sinopia editor made for Blue Core, including updates to the interface, functionality, and seed data. We will provide an overview of Sinopia, compare Sinopia Classic to Sinopia for Blue Core, and highlight plans for production cataloging in BIBFRAME. We will review recent developments to operational metadata such as data associated with the BIBFRAME AdminMetadata class, and outline ways to get started with BIBFRAME cataloging in Sinopia.
