Book excerpt: Linked data has become a punchline in certain circles of the GLAM (galleries, libraries, archives, and museums) community, derided as a much-hyped project that will ultimately never come to fruition. But the fact is, linked data is already happening now, evident in projects from Big Tech and the Wikimedia Foundation as well as the web pages of library service platforms. The goal of exposing cultural institutions’ records to the web is as important as ever—but for the non-technically minded, linked data can feel like a confusing morass of abstraction, jargon, and acronyms. Get conversant in linked data with this basic introduction from the Association of Library Collections and Technical Services (ALCTS). The book’s expert contributors summarize the origins of linked data, from early computers and the creation of the World Wide Web through RDF; walk readers through the practical, everyday side of creating, identifying, and representing semantically rich linked data using as an example the funk classic Mothership Connection album from the band Parliament; explain the concept of ontologies; explore such linked data projects as Open Graph, DBpedia, BIBFRAME, and Schema.org’s Bib Extension; offer suggested solo and group entry-level projects for linked data-curious librarians who wish to dive deeper; and provide a handy glossary and links to additional resources. This valuable primer on linked data will enable readers at any level of experience to get quickly up to speed on this important subject.
