Linked Data Principles



1. Use URIs as names for things




2. Use HTTP URIs so people can look up those names





3. When someone looks up a URI, provide useful information, using the standards RDF





3. When someone looks up a URI, provide useful information, using the standards RDF

4. Include links to other URIs, so that they can discover more
