Linked Data Principles

Linked Data Principles1. 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, SPARQL



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

Tim Berners-Lee - 2006

Linked Data Principles

Linked Data Principles1. Identify your things with URIs


2. When someone looks up your identifier give them information in a [Web] standard form



3. Include links to other things (URIs), so that they can discover more



3. Include links to other things (URIs), so that they can discover more

4. Enable follow-your-nose discovery/navigation

Data Open and/or Linked

Data Open and/or Linked1. Data can be open, while not being linked


2. Data can be linked, while not being open



3. Data which is both open and linked is increasingly viable



3. Data which is both open and linked is increasingly viable

4. The Semantic Web can only function with data which is both open and linked
