first phase • XSLT conversion tool from SDMX standard to RDF 2012 Datacube prototype
• Customization of XSLT Sarven Capadisli’s converter and Linked Data conversion of all I.Stat datawarehouse 2013 • LinkedStat publication as Linked Data , with SPARQL endpoint end first phase
WORK IN PROGRESS second phase • Tutorials and use cases on LinkedStat • From ★★★★☆ to ★★★★★ data: from 2014 LinkedSTAT to LOD connections
