  6. 6. Two Key IngredientsDigital Enterprise Research Institute 1. 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 Enabling Networked Knowledge 6 of 46

  22. 22. EuropeDigital Enterprise Research Institute  European Public Sector Information (PSI) Platform, to raise awareness and exchange good practices. More planned activities under CIP are foreseen.  LOD2- FP7 project to increase public access to high- value, machine- readable data sets generated by European, national/regional/local public administrations.  The Linked Open Data Around the Clock (LATC) FP7 Support Action supports interested partners to publish and consume Linked Data.  Digital Agenda Stakeholders’ Day: “Priority #3: Beyond raw data: public sector information, done well”. A discussion on what is next in Open Data  Provide Semantic Interoperability Center Europe (SEMIC) as a possible trusted registry infrastructure for vocabulary, metadata schemas and EU URI management (semantic assets)  Investigate ways of improving access to EC information Peristeras, V. ‘From Open to Linked Government Data’, http://linkeddata.future- Enabling Networked Knowledge

  24. 24. The 7 Best Practices for Producing LOGDDigital Enterprise Research Institute 1. Model the Data 2. Name things with URIs 3. Re-use vocabularies whenever possible 4. Publish human and machine readable descriptions 5. Convert data to RDF 6. Specify an appropriate license 7. Host the Linked Data Set Publicly and Announce it! Enabling Networked Knowledge
  25. 25. How the BBC makes WebsitesDigital Enterprise Research Institute  Develop a domain model  Populate your data model  Design URIs  Build pages  Apply layout and decor CSS  Test and iterate Mike Atherton, ‘Beyond the Polar Bear’ Enabling Networked Knowledge
