Our vision I

Contribute to a solid & fertile information ground for:

• inter-creativity• innovation

3

Our vision II

bring together

open spending <--> fixmystreet

--> is public spending effective?<-- can everyday problems provide input in spending decisions?

4

LOD in Greece: current status

• in its infancy – NO Apps yet• 2-3 stars• Open - not Linked• very limited public awareness

5

Main questions

ohow can we initiate the virtuous cycle of creation?

demonstrate LOD’s added valueusers & developers involvement

ohow to get the most out of data?local & global interconnections

6

Clarity program (“diavgeia”)

ohorizontal, huge, inspiring… ochange in paradigm in GR Open

Dataono validation rulesosome incomplete & false entriesoOpen but not Linked
