Digital
 Can be accessed worldwide;
 Does not take physical space
(beyond device);
 Easy to make correction and
update;
 Can include structure for
machine interpretation;
 Interactive user feedback;
 Personalized on-demand
content (e.g. RSS, Flipboard)
Print
 Tend to be focused on (and
only available in) a single
region;
 Takes up physical space;
 Difficult to make correction
and update;
 Difficult for machine to
interpret content;
 Many users still prefer the feel
of paper

Open data is data that can be freely used, reused and
redistributed by anyone - subject only, at most, to the
requirement to attribute and sharealike.

Open Gov Data (I)
 Principles:
— Data must be complete, primary, timely, accessible, machine
processable, non-discriminatory, non-proprietary, and license-
free.
 Main benefits:
— to provide transparency to increase governmental
accountability by releasing data produced by governments;
— to increase citizen engagement and participation in
governance process;
— to reduce government costs.

Linked Data (I)
"The Semantic Web is not a separate Web but an
extension of the current one, in which [data] is given
well-defined meaning, better enabling computers and
people to work in cooperation.“

CONCLUSION

28. I-Semantics 2013
9th International Conference on Semantic Systems
Traditional publishers will survive if they
 Leverage open data as much as possible;
 Leverage structured data to provide new functionality to
consumers;
 Leverage software to generate new structured data from
unstructured data (e.g. text);
 Be aware that traditional publishers are no longer your
main rivals;
 Promote innovation by
— Enabling employees to explore new technologies and
concepts;
— Having a group dedicated to innovation; and
— Having hackathons.
