The goals of Open Data

How technology can help here?





Challenge: getting data

- Data have to be easy to use in applications

- Not only big packages to download, integrate, adjust...

- ... but also simple APIs to get needed data on-the-fly

DATA CLOUD

RESTful ?Access data in the same way you access a web site, via a URL



Challenge: serendipity

- Data publishers (e.g. PAs) just make data available ...

- Data users (e.g. private companies) should add business value and innovation on top ...

- Innovation comes from unexpected use of data!

- How to discover new relate data?

- How to link/merge independently created data?

”Serendipity is when you find something that you were not expecting to find”[Wikipedia]



DATA IS LESS VALUABLE WHEN SILOED

your web site



Linked Data ingredients




- Things have names (a person, a city, a company)





- Let this names start with http://






- ...then we can get more data about things using a standard protocol







- ... others can directly point to things in my dataset (and vice-versa)








- Represent data (relations among things) as RDF








- Represent data (relations among things) as RDF

- Resource Description Framework is a W3C standard

- Semantic Web Applications:

- Access/browse a global interconnected DB

- Merge, mix data

- Perform powerful cross-domain queries



Challenge: leverage the entire Web of Data

- To create a data ecosystem an business opportunities PSI open data is not enough.

- A lot of data is out there (in web sites, in social media, etc.) ...

- ... and is already “kind of” structured.



+Work in progress....

WHAT WE DO IN PRACTICE ?



PSI to Linked Data+

Free APIs



Build data driven applications on top
