  • Open Governmental Data – and ideal testbed for Linked Data? Single Point of Access: European registry & collaboration for open government data Outreach & involve data providers - local, regional, national and European 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 LOD2 OGD Stakeholder Survey 30.06. 2011 http://lod2.eu
  • LOD2 Open Government Data Use Case: publicdata.euLOD2 OGD Stakeholder Survey 30.06. 2011 http://lod2.eu
  • OGD Stakeholder Survey: Results The LOD2 Open Government Data (OGD) Stakeholder SurveyLOD2 OGD Stakeholder Survey 30.06. 2011 http://lod2.eu
  • The LOD2 OGD Stakeholder Survey 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/ • Published in HTML, PDF & raw survey data in CSV & RDF for re-use under CC-BY licenseLOD2 OGD Stakeholder Survey 30.06. 2011 http://lod2.eu
  • OGD Stakeholder Survey: Results 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.LOD2 OGD Stakeholder Survey 30.06. 2011 http://lod2.eu
  • OGD Stakeholder Survey: Results 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.LOD2 OGD Stakeholder Survey 30.06. 2011 http://lod2.eu
  • OGD Stakeholder Survey: Results 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 havent listed JSON, RSS and YAML in this list, respondents have urged that in the free comment field.LOD2 OGD Stakeholder Survey 30.06. 2011 http://lod2.eu
  • OGD Stakeholder Survey: Results From where should the data come? The results show that "national" data is most important followed by "regional", "EU- wide" and "worldwide" data.LOD2 OGD Stakeholder Survey 30.06. 2011 http://lod2.eu
  • OGD Stakeholder Survey: Results 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"LOD2 OGD Stakeholder Survey 30.06. 2011 http://lod2.eu
  • OGD Stakeholder Survey: Results 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.LOD2 OGD Stakeholder Survey 30.06. 2011 http://lod2.eu
  • OGD Stakeholder Survey: Results 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.LOD2 OGD Stakeholder Survey 30.06. 2011 http://lod2.eu
  • OGD Stakeholder Survey: Results Publishing the Survey as RDFLOD2 OGD Stakeholder Survey 30.06. 2011 http://lod2.eu

  • OGD Stakeholder Survey: Results Publishing the Survey as RDF - 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 togetherLOD2 OGD Stakeholder Survey 30.06. 2011 http://lod2.eu
  • OGD Stakeholder Survey: Results Publishing the Survey as RDF  RDF-Schema creation to represent Surveys http://ns.aksw.org/survey/LOD2 OGD Stakeholder Survey 30.06. 2011 http://lod2.eu

  • OGD Stakeholder Survey: Results Publishing the Survey as RDF  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)LOD2 OGD Stakeholder Survey 30.06. 2011 http://lod2.eu
