  • 13. Data transformationin: CSVout: RDF triplesiterative, so automate!
  • 14. Data publishingBaseline goal:– provide access to the dataPractical considerations:– Just “follow-your-nose” linked data?– or SPARQL?– or an API?– ….

  • 28. Initial learningswriting SPARQL by doing– in context– with feedbackhard to balance different user needs– explore vs. guide– real user inputdownload– important– RDF to useful CSV is hard
  • 29. Dissemination
  • 30. Conclusions & next stepsformal evaluation– involve partner organizations eg Rivers Trust“generated excitement”– key engagement tool for catchment managementinformation– summer 2014 draft river basin management plansbig picture– reference spine for integrating data from otherenvironmental stakeholders
