Linked Data in Libraries

This document discusses using linked data in libraries. It notes that several national libraries have implemented linked data projects. Linked data allows for entity-based descriptions of things on the web using common vocabularies. This helps users more easily discover resources across institutional silos. The document advocates for libraries to publish their data as linked open data using common schemas, and transform records into interconnected web entities rather than standalone data. This enables new discovery experiences and ways for users to explore library collections on the web.
