10. Challenge: serendipity
”Serendipity is when you find something that you were not expecting to find”
[Wikipedia]
- 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?
