Open Data zwischen Anspruch und Wirklichkeit

Abstract: Wie sieht vor diesem Hintergrund die Wirklichkeit offener Datenin Europa aus? a) Vielzahl von öffentlichen Organisationen veröffentlicht bereits open data oder beginnen gerade damit, jedoch auf unterschiedliche Art und Weise b) Open data wird fragmentiert veröffentlicht, lokal, regional, national oder pan-Europäisch c) Metadaten sind oft uneinheitlich, unvollständig oder nicht akkurat d) Situation von open data erscheint fragmentiert und schwer zu überschauen, was zahlreiche Fragen auf wirft: - Welche Kataloge und Datensindverfügbar? - Gibt es (inter)nationale Trends? - Wo finden sich besonders vielversprechende open data Ressourcen?

Open Data: Versunkene Schätze oder digitaler Datenmüll?

Abstract: Open Data ist weltweit ein emergentes Phänomen. Dabei verlieren Nutzer oftmals den Überblick, welche Daten es wo überhaupt gibt. Das von der Europäischen Kommission geförderte FP7-Projekt OpenDataMonitor entwickelt derzeit eine Web-Plattform, welche darüber Aufschluss geben wird, wo qualitativ hochwertige offene Daten auffindbar sind, wodurch sich diese auszeichnen und wie offene Daten für eine bessere Nutzung harmonisiert werden können. Der Artikel beschreibt die methodische Vorgehensweise im Projekt und stellt erste Analyseergebnisse dar.

The Social Shaping of Open Data through Administrative Processes

Abstract: Many models have been provided in the last years that aim at describing an optimal open data publication process. However, they fail to explain the different outcomes of open data initiatives. Based on qualitative research this paper conceptualises the open data phenomenon as a set of techno-political arenas in which different interests of a variety of actors potentially and actually collide. The micro-political arena model constitutes an instrument to delineate the social and institutional context of open data that can be employed to explain the successes, as well as the failures of individual open data projects.

Providing, guarding, shielding: Open Government Data in Spain and Germany

Abstract: The trend to publish public sector information (PSI) openly on the Internet has grasped attention worldwide under the term open data. However, despite its global reach and claim of some of the movement's activists, the national and local results of the phenomenon differ considerably. These differences have so far not been sufficiently explained. This article understands open data projects as techno-scientific artefacts negotiated within a network of various actants following vested interests. Building on Latour's theory of actor-networks this article conceptualises open data projects as cocreated phenomena transcending the social-technical distinction. This helps us to understand both the particularities of single projects, as well as the continuities specific administrative systems imprint on the formation of open data regimes. This research investigates the situation of open data in Germany and Spain, thereby focusing on national level as well as local level projects. Methodologically it is build on qualitative empirical data collected through document analysis and more than 30 in-depth interviews with experts from the public sector as well as users and open data advocates from outside the public sector.

The Tau of Data: A New Metric to Assess the Timeliness of Data in Catalogues

Abstract: We review existing studies that assess the timeliness of data in catalogues and propose a new metric: tau, the percentage of datasets up-to-date in a data catalogue. Obsolete data will stifle innovation, whereas spotlighting timeliness can foster efficiency and support the sustainability of the open data ecosystem, for example, by encouraging automated publication of data.We validate the tau in three case studies: the World Bank catalogue, the UK data catalogue ( and the London Datastore. For the World Bank and London we find that roughly half of the datasets are up-to-date, whereas performs worse. However, there are considerable caveats when it comes to missing and undocumented metadata. The tau of data is easy to implement, can be readily interpreted and be generalised with further parameters across all data catalogues.

Conceptualizing Open Data Ecosystems: A timeline analysis of Open Data development in the UK

Abstract: In this paper, we conceptualize Open Data ecosystems by analysing the major stakeholders in the UK. The conceptualization is based on a review of popular Open Data definitions and business ecosystem theories, which we applied to empirical data using a timeline analysis. Our work is informed by a combination of discourse analysis and in-depth interviews, undertaken during the summer of 2013. Drawing on the UK as a best practice example, we identify a set of structural business ecosystem properties: circular flow of resources, sustainability, demand that encourages supply, and dependence developing between suppliers, intermediaries, and users. However, significant gaps and shortcomings are found to remain. Most prominently, demand is not yet fully encouraging supply and actors have yet to experience fully mutual interdependence.
