Open Governmental Data – and ideal testbed for Linked Data?

Close cooperation with W3C eGov IG, OKFN’s OpenEUdata, PSI & grassroots efforts

CKAN.org | semic.eu | EIF European Interoperability Framework | ICT2010 Networking Session

UIs and Personalization

Individual mashups of data with other sources

Notification/subscription service based on personal preferences

Transparency wishlists, upload revisions, derivates

Create and publish queries, reports and visualisations

Single Point of Access: European registry & collaboration for open government data Outreach & involve data providers - local, regional, national and European

LOD2 Open Government Data Use Case: publicdata.eu

http://lod2.eu/



The LOD2 Open Government Data (OGD)

Stakeholder Survey

http://lod2.eu/


WHY

• Involve OGD community in Europe (& worldwide) in publicdata.eu process

• Ask for their needs & requirements in the area of OGD & publicdata.eu

• Use results for requirements elicitation for the LOD2 use case: publicdata.eu

HOW

• Set up by OKFN & SWC with support from DERI, Wolters Kluwer and ULEI

• Easy to use online survey tool (surveygizmo.com)

• Promoted via blogs, mailings, mailing lists and additional viral marketing

channels as well as at related events in Europe & by the EC

• Duration: 5 weeks

• 329 participants

• Results available since May 2011: http://survey.lod2.eu/

Interest in ‚domains of data‘

For the complete results you can see that "Geospatial information", "Scientific data" and "Environment" data are the top ranked domains.

http://lod2.eu/


Currently used formats

For the preferences on the format of data you can see that current "traditional" formats like HTML, PDF, CSV/XLS and DOC/RTF are preferred.


http://lod2.eu/


Requested (future) formats

In general you can also see that ideally ("in future") formats like "XML", "RDF" and "APIs" will become more importance. It seems that all user types find DOC, RTF and PDF not a suitable solution for a future Open Government Data infrastructure. As we haven't listed JSON, RSS and YAML in this list, respondents have urged that in the free comment field.


http://lod2.eu/


From where should the data come?

The results show that "national" data is most important followed by "regional", "EU-wide" and "worldwide" data.


http://lod2.eu/


What is important for quality assurance?

The complete results show that "provenance/source of data" followed by "format of data", "completeness of meta data", "ranking / comments by users" and "official certificates"


http://lod2.eu/


What features does a EU data catalogue need?

The complete results show that "providing raw datasets", "information about versioning of data sets" and "searching, exploring, grouping and clustering of data sets" are the features which are "expected to have" while "crowd sourcing mechanism (e.g. data repair)", "alerts on regional information" and "analysis and visualisation tools" have the highest rating in the "like to have" category.


http://lod2.eu/


What is also expected on publicdata.eu?

For this question "white papers & best practice", "news on Open Government Data" and "use cases & sucess stories" are "expected to have" while "ideas for apps", "events" and again "use cases & success stories" are ranked highest in the "like to have" category.

Publishing the Survey as RDF

http://lod2.eu/


- Questionnaire and results of the survey published as - HTML,

- CSV and - PDF

-These formats are only for humans which represent use case specific views



http://lod2.eu/


- Publishing in RDF give further benefits: -Aggregating data to enable other user(-generated) aspects (SPARQL)

- Interlink the data with other datasets … - … which enable (advanced) users to create more complex queries (aggregating resources from non-local information spaces like DBpedia )

- Schema and data can be queried together



http://lod2.eu/


RDF-Schema creation to represent Surveys


http://ns.aksw.org/survey/


http://lod2.eu/


Transformation of the Data Questionnaire delivered as PDF containing 5 survey sections, 60 questions, 221 Options for single -/multiple - choice questions -> modeled with the survey vocabulary Resultset of the Survey tool delivered as CSV which is being transformed with PHP

Creating RDF-Resources for every : Participant: Response (329) Answers to Questions (12891)

Overall ~ 70,000 triples



http://lod2.eu/


Deployment of the Data Upload the knowledge base into Virtuoso

Questionnaire and survey results as one model

Universal Server with multiple RDF / LOD functionalities

Adding metadata to the OGD-Survey-model (contributor, publisher, license)

Publishing the model via OntoWiki human and machine friendly HTML/JS – Web interface to explore and maintain the data SPARQL Editor / Endpoint LOD client and server
