Open Government ist spätestens seit der 'Transparency Directive' von US Präsident Barack Obama, kurz nach seinem Amtsantritt im Jänner 2009, im Bereich eGovernment ein weltweit bedeutendes Thema!
Hier wird eine moderne Zusammenarbeit von Politik, Verwaltung, Zivilgesellschaft und Wirtschaft postuliert, mit den Zielen:
• Transparenz zu fördern• Partizipation und • Kollaboration zu ermöglichen
Teilbereich von Open Government = Open Government Data
Was ist Open Government?

Lucke & Geiger (Zeppelin Universität)Offene Verwaltungsdaten sind jene Datenbestände des öffentlichen Sektors, die von Staat und Verwaltung im Interesse der Allgemeinheit ohne jedwede Einschränkung zur freien Nutzung, zur Weiterverbreitung und zur freien Weiterverwendung frei zugänglich gemacht werden.
OKFO – Open Knowledge Forum ÖsterreichOpen Government Data is a worldwide movement to open data (& information/content) of the government / public administration* - that is NOT personal (individual related) – in human- AND maschine-readable open (non proprietary) formats for re-use (by civil society, economy, media, academia AND politics & public administration itsself)!
* ….. data and information produced or commissioned by government or government controlled entities
1. Vollständigkeit Alle öffentlichen Daten werden verfügbar gemacht. Als Öffentliche Daten werden hierbei Daten verstanden, die nicht berechtigten Datenschutz-, Sicherheits- oder Zugangsbeschränkungen unterliegen.
2. PrimärquelleDie Daten werden an ihrem Ursprung gesammelt. Dies geschieht mit dem höchstmöglichen Feinheitsgrad, nicht in aggregierten oder sonst wie modifizierten Formaten.
3. ZeitnahDaten werden so zügig, wie zur Werterhaltung, notwendig zur Verfügung gestellt.
4. Leichter ZugangDer Zugang zu Daten soll so leicht wie möglich sein (z.B.: Angebot von Formaten, APIs etc).
5. MaschinenlesbarDaten werden zur automatisierten Verarbeitung strukturiert zur Verfügung gestellt.
6. Nicht diskriminierendDaten sind für ALLE verfügbar, ohne dass z.B. eine Registrierung notwendig ist.
7. Nicht proprietärDaten werden in standardisierten Formaten bereit gestellt, über die keine juristische Person die alleinige Kontrolle hat.
8. LizenzfreiDaten unterliegen keinem Urheberrecht, Patenten, Markenzeichen oder Geschäftsgeheimnissen. Sinnvolle Datenschutz-, Sicherheits- und Zugangsbeschränkungen sind zulässig.
Die Einhaltung dieser Prinzipien ist überprüfbar.PLUS: Sunlight Foundation, August 2010: 9) Dauerhaftigkeit / Stetigkeit & 10) Nutzungskosten
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.
Was ist wichtig, wenn man über ‚OGD in Use‘ spricht?•Interoperabilität, um einfache & breite Nutzung zu gewährleisten•Menschen UND Maschinenlesbare Daten & Metadaten•In OFFENEN Formaten•Für eine rasche, einfache und kostensparende Datenintegration•Um Effekte auf verschiedenen Ebenen zu generieren: lokal – regional – national – EU weit & weltweit
Für verschiedene Zielgruppen mit unterschiedlichen Interessen!•Öffentliche Verwaltung (auch für interne Verwendung!!)•Politiker & Entscheidungsträger•Bürgerinnen & Bürger (Citizen Analysts)•Wirtschaft & Industrie (Datenintegration, -anreicherung, APPs)•(Daten) Journalismus, Medien & Verlage•Wissenschaft & Bildung
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 its full potential.
The Vision of the new Internet
Also take the Metadata into account!
Towards Open Government Metadata (Sept 2010)
In the EU eGovernment Action Plan semantic interoperability is mentioned “…as an essential precondition for open, flexible delivery of eGovernment services”.
Metadata IgnorancePublic administrations should become aware of the importance of Metadata in eGovernment and the need for coherent relevant management policies.
Scattered or Closed MetadataPublic 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 MetadataPublic administrations should provide services to query, browse and export their Metadata in amachine-readable and preferably non-proprietary format (e.g. CSV, XML).
Linked Open MetadataPublic administrations should consider applying linked metadata policies, including use of RDFto document their Metadata, persistent design, use and maintenance of URIs, linking toexternal vocabularies/schemata, harmonize their resources to third parties' resources etc.
He also developed the first industrially practical screw-cutting lathe in 1800, allowing standardisation of screw thread sizes for the first time. This allowed the concept of interchangeability (a idea that was already taking hold) to be practically applied to nuts and bolts. Before this, all nuts and bolts had to be made as matching pairs only. This meant that when machines were disassembled, careful account had to be kept of the matching nuts and bolts ready for when reassembly took place.http://en.wikipedia.org/wiki/Henry_Maudslay

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.
Where is the Semantic Web used? Under the hood of lots of products!
