The document discusses the benefits of linked open government data as a national digital infrastructure and knowledge society enabler in Europe. It advocates publishing open data using web technologies like URIs and RDF, and linking data to other sources to facilitate integration. Examples of best practices from data.gov.uk and reegle.info are provided. Linked data is presented as an incremental and cost-effective approach to data integration within governments.

3. From Open Data to Linked Open Data
Publish Data!
•Organise Data!
•License Data!
•Raw Data now!
Use Web-Technologies
•Provide an API!
• The web is an Ecosystem Use Linked Data!
• Networked Data creates
Network Effects • Give things an URI!
• Lowers Costs of Data • Use RDF for Publishing!
Integration • Link your Data to other Data
(as well as the data models)!
• Provide a Standard-API

12. Pay-as-you-go!
“Linked Data technologies can easily
fill the gap between unstructured
Intranet search and expensive &
complicated Service-oriented
Architectures. 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 structures in the
enterprise.”

13. Conclusion
Beside lots of other topics (definitions, legal issues, impact on
society and economy, et al.) the following ones should be taken into
account when planning Open (Government) Data projects (local,
regional, nationwide, EU-wide)
• Open Government Data is important for the digital infrastructure
• The 5th star of Tim Berners Lee‘s model should be the vision
• Harmonisation of data / information structure is important
• Harmonisation of standards ensures interoperability
• Harmonisation of Meta Data structure is a must-have
(A unified method to describe the data)
• This harmonisations should be internationally compatible!

14. Open Government Data (OGD) Austria
About the initiative (April 2010 - May 2011) – http://www.opendata.at
Our common goal is to open government (non-personal) data for
re-use in a human- and machine-readable (preferably open) format
similar to existing initiatives and activities in US, UK or Australia.
The OGD Austria Initiative works in tight co-operation with the
public sector in Austria – the local, regional and national government,
federal agencies and organisations. Furthermore the initiative works
along the existing eGovernment initiatives and activities of the
Austrian government.
The Initiative works closely with other European Open Data
Initiatives – in the areas of co-operation, lessons learned, best
practises, R&D etc. At the moment the OGD Austria works with
initiatives from Germany, the Netherlands, Belgium, Spain and the UK.
