  • 3. Creating Knowledge out of Interlinked Data TimBL’s 5-star plan for open data ★ Make your data available on the Web under an open license ★★ Make it available as structured data (Excel sheet instead of image scan of a table) ★★★ Use a non-proprietary format (CSV file instead of an Excel sheet) ★★★★ Use Linked Data format (URIs to identify things, RDF to represent data) ★★★★★ Link your data to other people’s data to provide contextMore: http://lab.linkeddata.deri.ie/2010/star-scheme-by-example/ EU-FP7 LOD2 Project Overview .
