  35. 35. Linked Data PrinciplesDigital Enterprise Research Institute www.deri.ie 1.  Use URIs to identify the “things” in your data 2.  Use HTTP URIs so people (and machines) can look them up on the Web 3.  When a URI is looked up, return a description of the thing in a structured format (RDF) 4.  Include links to related things to provide context http://www.w3.org/DesignIssues/LinkedData.html Enabling Networked Knowledge
