Linked Data: Design Principles

1. Use URIs as names for things2. Use HTTP URIs so that people can look up those

names.3. When someone looks up a URI, provide useful

information, using the standards (RDF*, SPARQL)4. Include links to other URIs. so that they can discover

more things

“Open data and content can be freelyused, modi�ed, and shared by anyone for

any purpose”
