4. What is Open Government?
The basic idea of Open Government is to establish a modern
cooperation among politicians, public administration,
industry and private citizens by enabling more transparency,
democracy, participation and collaboration.
Some of the most important enablers for Open Government are
free access to information and the possibility to freely use and
re-use this information (e.g. data, content, etc).
After all, without information it is not possible to establish a
culture of collaboration and participation among the relevant
stakeholders.
Therefore, Open Government Data (OGD) is often seen as a
crucial aspect of Open Government.

7. What is Open Government Data?
Open Government Data (OGD) is a worldwide
movement to open up data (& information) of the
government / public administration* - that is NOT
personal (individual related) – in human- and
maschine readable open formats (non proprietary)
for use & re use!
OPEN stands for lowering the barriers to ensure as broad as
possible re-use (for everybody)!
There is a new paradigm in publishing Government Data
= look, take and play!
* ….. data and information produced or commissioned by government or government controlled entities

8. Open Government Data in Europa
20. 10. 2011, OGD Camp 2011 Warsaw - http://blogs.ec.europa.eu/neelie-kroes/tag/open-data/
I’ve said before that I’m a big fan of open data. Opening up public data will get citizens involved
in society and political life, increase the transparency of public administration, and improve public
decision making. Those benefits cannot be overestimated. And public data can be used in many
unexpected ways, too: as the father of the Internet, Tim Berners-Lee, put it: “if people put data onto
the web… it will be used by other people to do wonderful things in ways that they never would have
imagined”.
There’s a huge amount of money here, and a huge amount of opportunity. I want to see Europe
at the forefront of this development. So I‟m going to be taking action to open up Europe‟s public
sector, by promoting creative and innovative re-use of public data.

11. Principles of Open Government Data
http://sunlightfoundation.com/policy/documents/ten-open-data-principles/
1. Completeness
All public data are made available. Public data are data that are not subject to valid privacy, security
or privilege limitations, as governed by other statutes.
2. Primacy
Data are published as collected at the source, with the finest possible level of granularity, not in
aggregate or modified forms.
3. Timeliness
Data are made available as quickly as necessary to preserve the value of the data.
http://www.opengovdata.org/home/8principles
4. Ease of Physical and Electronic Access
Data are available to the widest range of users for the widest range of purposes.
5. Machine readability
Data are reasonably structured to allow automated processing of it.
6. Non-discrimination
Data are available to anyone, with no requirement of registration.
7. Use of Commonly Owned Standards (e.g. open formats)
Data are available in a format over which no entity has exclusive control.
8. Licensing
Data are not subject to any copyright, patent, trademark or trade secret regulation. Reasonable
privacy, security and privilege restrictions may be allowed as governed by other statutes.
Finally, compliance must be reviewable.

13. Also take the Metadata into account!
Towards Open Government Metadata (Sept 2011)
In the EU eGovernment Action Plan semantic interoperability is mentioned “…as an
essential precondition for open, flexible delivery of eGovernment services”.
Metadata Ignorance
Public administrations should become aware of the importance of Metadata in eGovernment
and the need for coherent relevant management policies.
Scattered or Closed Metadata
Public administrations should organize the scattered Metadata in structured repositories,
catalogues or libraries and provide open access to the collected resources.
Open Metadata for Humans & Open Reuseable Metadata
Public administrations should provide services to query, browse and export their Metadata in a
machine-readable and preferably non-proprietary format (e.g. CSV, XML).
Linked Open Metadata
Public administrations should consider applying linked metadata policies, including use of RDF
to document their Metadata, persistent design, use and maintenance of URIs, linking to
external vocabularies/schemata, harmonize their resources to third parties' resources etc.

14. David Eaves Centre for the Study of Democracy, Canada
„
Words to every OGD advocate:
Building an Open Government
Data Infrastructure is like
building a electric power grid. It„s
hard to measure it„s impact on
society and on economy, but it is
evident that there is one.

26. The Vision of the New Internet
Linked Data realizes the vision of
evolving the Web into a global
data commons, allowing
applications to operate on top of
an unbounded set of data
sources, via standardised
access mechanisms.
I expect that Linked Data
will enable a significant
evolutionary step in leading
the Web to ist full potential.

27. Linked Open Data
Benefits & Potentials

28. LOD Benefits: An Overview
• Less replication (offering same datasets in
different places) & thereby cost saving
• Encouragement to re-use existing datasets
on the basis of open standards
• Clear which datasets are providing similar /
same information
• More innovation because datasets can be
put in a new context and lead to
interesting applications & create
knowledge
• LOD can provide a powerful digital
infrastructure for data management
28

29. The Power of Linked Open Data
• Enables web-scale data publishing - distributed publication with web-
based discovery mechanisms
• Everything is a resource – follow your nose to discover more about
properties, classes, or codes within a code list
• Everything can be annotated - make comments about observations,
data series, points on a map
• Easy to extend - create new properties as required, no need to plan
everything up-front
• Easy to merge - slot together RDF graphs, no need to worry about name
clashes
• Easy use and re-use on top of common schemas AND schema mapping
• Allows complex querying of several distributed data sources & systems

33. LOD – Huge Economic Potentials
Data have swept into every industry and business function and are now an
important factor of production, alongside labor and capital.
Harnessing big data in the public sector has enormous potential, too. If US health
care were to use big data creatively and effectively to drive efficiency and quality,
the sector could create more than $300 billion in value every year. Two-thirds of
that would be in the form of reducing US health care expenditure by about 8 percent.
In the developed economies of Europe, government administrators could save
more than €100 billion ($149 billion) in operational efficiency improvements
alone by using big data, not including using big data to reduce fraud and errors and
boost the collection of tax revenues.
And users of services enabled by personal location data could capture $600 billion in
consumer surplus.

37. Linked Data: pay-as-you-go!
“Linked Data technologies can easily
fill the gap between unstructured
Intranet search and expensive &
complicated Service Oriented
Architectures (SOA).
Compared to SOA, Linked Data is a
pay-as-you-go strategy, where data
integration can be performed
incrementally and in sync with the
requirements and evolution of the data
