Web Driven Revolution For Library Data
Richard Wallis, an OCLC Technology Evangelist, discusses how libraries can make their data more visible and connected on the web by publishing it as linked open data using common web vocabularies like Schema.org. Currently, library linked data exists in silos using different local vocabularies, making the data hard to discover and integrate. Adopting Schema.org could help library data reach the billions of web pages and domains that already use this general purpose vocabulary to describe things on the web.
