The document discusses the Semantic Web and Linked Open Data (LOD), which aim to make data accessible and processable by both humans and machines. It outlines the framework for representing structured content using RDF, including the use of URIs for data identification and querying with SPARQL. Additionally, it highlights the evolving role of librarians in managing digital information and facilitating user access in the 21st century.
