7 7 Principles of linked data Use URIs to identify things. Use HTTP URIs so that these things can be referred to and looked up by people and user agents. Provide useful information when its URI is looked up, using standard formats such as RDF/XML. Include links to other, related URIs in the exposed data to improve discovery of other related information on the Web.  Ex Libris Ltd., Internal and Confidential These technical principles are very brought. How to implement them depends on the use case. These technical principles are very brought. How to implement them depends on the use case.
