• Origins in electronic library catalogs from the 1970s (e.g., WorldCat, which was created in 1971)
• Moreover, the development of library standards, such as MARC or Z39.50, were designed only for the library community in the 1960s and 1970s, respectively.
• This legacy has complicated efforts to join that wider search stream, and it also led burgeoning web entities such as DBpedia, which offers a Semantic Web mirror of Wikipedia, to originally bypass library data

• LODLAM initiative product of increasingly connected culture (MIT Sloan
school, NEH, Internet Archive)
• Since January 2011, the International Linked Open Data in Libraries,
Archives, and Museums Summit (“LOD-LAM”) have convene leaders in
their respective areas of expertise from the humanities and sciences “to
catalyze practical, actionable approaches to publishing Linked Open Data,
specifically:
• Identify the tools and techniques for publishing and working with Linked Open Data.
• Draft precedents and policy for licensing and copyright considerations regarding the
publishing of library, archive, and museum metadata.
• Publish definitions and promote use cases that will give LAM staff the tools they need
to advocate for Linked Open Data in their institutions.”

Linked Open Data Principles
1. Use URIs as names for things
1. Use HTTP URIs so that people can look up those names
1. When someone looks up a URI, provide useful
information using standards (RDF, SPARQL)
1. Include links to other URIs so that they can discover more
things

names

more things
