The document discusses the history and evolution of linked data. It began in the 1990s with static HTML pages and has evolved to include dynamic content, web applications, and semantic connections between data across the web. Linked data aims to solve interoperability issues by linking related data together using common identifiers and standards. It allows for open reuse of data and has economic, social, and innovation benefits by making disparate sources of information more connected and useful.
