In the Land of Shared Data
“A piece of data or
content is open if
anyone is free to
use, reuse, and
redistribute it
— subject
only, at most, to
the requirement
to attribute
and/or share-alike.”
Big Data

Data
“Big data” refers to datasets whose size is beyond
the ability of typical database software tools to
capture, store, manage, and
analyze.”

5. Open Data: International Context
 Some EU legislative initiatives and policy actions in the
field of open data
 Revision of the Directive 2003/98/EC on the re-use of public
sector information (published on 26 june 2013)
 EC Horizon 2020 offers opportunities for multi-disciplinary,
collaborative research in the use of Big Data and Open Data to
support key societal challenges (health, energy, transport, food,
climate, and inclusive, innovative and secure societies)
 At the G8 level, an “Open Data Charter” was signed by
G8 leaders in June 2013 to promote transparency,
innovation and accountability
 Istat made available some key datasets (http://dati.gov.it)
according to the agreements in the Action Plan

6. Open Data: National Context
Statistical Data
• Statistical data is already “open”
 Current legislation states that statistical data “belong”
to the community and must be available to everyone
upon request
• Statistical data is subject to confidentiality
constraints

12. Conclusions
 Open Data:
 Many things done…

 Big Data:
 Several opportunities
 Smart cities
Question: Are Census Data Big Data?
Answer: Not actually, but…it will be nice to have
them as Open Data, or even better as Linked
Open Data!
