3. wish list fo the next year
• Open Government Data as a Right
• More Schemas (Knowledge APIs) – keep it focused, let’s not try to boil
the ocean
• Open Data as a Platform, Not a Commodity
• Massive Interconnection Between Open Data Sites
• Open Corporate Data (for and by Corporates)
• Standards (e.g. for catalog metadata) for Data Portals and Data Hubs
• Open Data for Growth – making clear the the connection
• Strong international norms for data inventories
• Organizational identifiers – Dunn & Bradstreet should be replaced with
open data
• MiData – getting personal data out of corporates and government back
into the hands of the people whose data it is

5. Open data features
Complete Primary Timely Accessible
Machine-readable
Non-proprietary License-free Reviewable
Discoverable Permanent Access
Redistribution Reuse Description
Metadata Attribution Integrity
Absence of Technological Restriction

6. Open Linked Data
★ make your stuff available on the Web
(whatever format) under an open license
★★ make it available as structured data
(e.g., Excel instead of image scan of a table)
Tim Berners Lee
★★★ use non-proprietary formats
(e.g., CSV instead of Excel)
★★★★ use URIs to identify things, so that people can point at your
stuff
★★★★★ link your data to other data to provide context

7. Linked Data Ingredients
Things have names
(a person, a city, a
company)
Let this names start
with http://
Represent data
(relations among
things) as RDF

an italian dataset: ISTAT immigration :)

15. How to join a dataset in this cloud?
First [...] publish data according to the Linked Data principles.
1.Please add it to CKAN

20. Next steps to the five stars ...
Il Trentino deve farsi protagonista del
movimento Open Data in Italia e, nel
2012, avrà l'occasione di mettersi alla
guida dell'avanguardia concentrata sulla
creazione di SEMPLICI best practices
per una semantica condivisa! (Linked
