This document discusses three options for libraries to implement linked data: BIBFRAME 2.0, Schema.org, and Linky MARC. BIBFRAME 2.0 is a library standard for linked data but is not recognized outside the library community. Schema.org is the main standard for structured data on the web and could increase library discoverability, but lacks detail for library cataloging. Linky MARC adds HTTP URIs to existing MARC records to preserve entity identifiers without converting to linked data. The document also proposes a new open project called "bibframe2schema.org" to map BIBFRAME to Schema.org and promote its adoption for libraries.
