Outline
① our vision② LOD in Greece③ main questions④ the Clarity program
(“diavgeia”) ⑤ WHERE MY MONEY GOES App⑥ ontology engineering ⑦ to the future

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

WHERE MY MONEY GOES in Greece publicspending.gr
• the first LOD App in Greece (June 2012)
• daily updates• open spending linked data,
endpoint & visualizations

some last thoughts
ofirst App on the Greek LODobased on ontological modelingoRe-use of main vocabularies oco-operations &
interconnections are in the top of our agenda
omotivate people to be involved
