RDF – Resource Description Framework Graph based Data – nodes and arcs ¨ Identifies objects (URIs) ¨ Interlink information (Relationships) 2. Vocabularies (Ontologies) ¨ provide shared understanding of a domain ¨ organise knowledge in a machine-comprehensible way ¨ give an exploitable meaning to the data

- 22. Digital Enterprise Research Institute www.deri.ie Enabling networked knowledge Linked Data Principles 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
