The document discusses the benefits and challenges of transitioning library data to linked data standards to make the data more accessible and interoperable on the web. It outlines principles of linked data and how library data could be transformed by assigning URIs to concepts, linking data sources, and storing data as RDF triples. Barriers include outdated library processes and standards like MARC that inhibit innovation, but initiatives like RDA, OpenLibrary, and data projects from the German National Library are helping advance the linked library data vision.
