Open data is freely available information that anyone can use for any purpose without cost. It aims to increase transparency, economic growth, and social good, while personal data is not considered open. Linked data connects related open data through web identifiers and forms a web of data, allowing for relationships between different data sources like social networks, interest graphs, health information, and fictional universes. People can get involved with open data by using resources on data portals and exploring the connections between data.
