  • 58. Linked Data Principles
  • 59. Linked Data Principles1. Use URIs as names for things
  • 60. Linked Data Principles1. Use URIs as names for things2. Use HTTP URIs so people can look up those names
  • 61. Linked Data Principles1. Use URIs as names for things2. Use HTTP URIs so people can look up those names3. When someone looks up a URI, provide useful information, using the standards - RDF
  • 62. 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 4. Include links to other URIs, so that they can discover moreTim Berners-Lee - 2006
