2 Economy after the Web New form of property Public, Private, Peer (e.g. Wikipedia) The right to: Use-modify-benefit-transfer resources Energetic & connected consumption Pro-sumption 2

3 Research question Web economy: from potential to actual Enable new virtuous cycles in the economy through Linked Open Data 3

5 EU Unification: the institutions Best in theory – poor in practice a (complicated) market example monetary policy, currency, eurozone European Single Market fiscal policy FORTHCOMING 5

6 EU Unification: the technology Linked Data or Web of data “publish once, use many times”. different consumers extract different slices of the data for different purposes publish in context: value & “meaning” 6

7 EU Unification: the technology Linked Data (LD) + Open Data =LOD Economic LOD as “data currency” 7

12 Economic LOD: engineering 12

13 Government Budget heterogeneous repositories & methods (mainly PDF) 13

14 Tenders Closed data in HTML Public Contracts Ontology (PCO), e.g. –pco:Contract and pco:AwardCriterion Common Procurement Vocubulary now working on linking our ontology to: –Payments Ontology –GoodRelations –FOAF 14

15 Spending most dynamic & open part increasing number of countries/cities raw & structured data leader: the Greek Clarity project spending decisions ex-ante to execution Actually every decision 15

16 ( ***** ) based on Greek Clarity & Tax information semantify, interconnect, clean, visualize, SPARQL endpoint, daily update PSGR ontology Links to –WESO products classif. –UK Payments Ontology –DBpedia and Geonames –…more to come 16

17 Business Information Registries: mainly closed Key standards –Classification of Products by Activity (CPA) –eXtensible Business Reporting Language (XBRL) 17
