Enipedia.tudelft.nl: Problem
I
We need more and better data for understanding, analyzing
and modeling the future of the world’s systems.
I
The world is getting extremely complex and connected so that
we cannot afford to limit ourselves to analyzing it in isolation.
I
The data, the analyzes and the concerned individuals need to
connect.

Enipedia.tudelft.nl: Solution
We propose the following process:
1. Publishing public/governmental/institutional data-sets and
linking them together - and to the rest of the already ”linked
data”
2. Creating tools to enable the data to be inspected, used,
curated in a variety of applications & contexts - and by many
more users.
3. Connecting the authors and the users of the (domain) data
into communities that eventually take ownership of the data
and its maintenance.
