The publication of Open Government Data (OGD) is expected to deliver economic value creation through innovation. In any OGD-based value creation, it is essential to formulate a value proposition (VP). However, previous literature has devoted little attention to the tools that support the formulation of OGD-based VP, and none has evaluated the performance of such tools with OGD infomediaries. In this article, we evaluate and compare the Business Model Canvas (BMC) and the Open Data Canvas (ODC) performance in supporting the formulation of VP. Questionnaire feedback was obtained from infomediaries who formulated OGD-based VP using the BMC and the ODC. The results show a superiority of either the BMC or the ODC in terms of perceived usefulness, depending on the focus of the feasibility evaluation of the VP. The ODC provides OGD-specific guidance on evaluating technical feasibility while the BMC covers economic feasibility more extensively. We recommend investigating the emerging field of OGD-based VP formulation tools by replicating our research with other types of infomediaries, in other settings, and completing it with qualitative insights.@en

Government policies focused on Open Government Data (OGD) often aim to stimulate the provision of public, interoperable data towards any user, including lay citizens, through online portals. However, these OGD portals are mostly developed for expert users. This hinders the realization of critical values such as transparency, empowerment, and equality of access. Following a Design Science Research approach, this study aims to examine how gamification can help tailor OGD portals for lay citizens. As a pre-condition to this goal, we identify requirements toward OGD portals through twenty interviews with experts and lay citizens. Compared to expert users, lay citizens expect an OGD portal with a more playful interface, vulgarized content, customized visualizations, and transparency-related datasets in a human-readable format. Second, we develop our research artifact, the OGD portal prototype, implementing fifteen design propositions using gamification theory to address lay citizens’ requirements. Third, the evaluation with ten lay citizens reveals the perceived usefulness of the design propositions. Badges were evaluated as most useful to highlight portal relevance. This study contributes to OGD theory development by identifying lay citizens' requirements towards OGD use. Furthermore, this study is the first to reveal the usefulness of implementing notions from gamification theory into OGD portal design. Finally, practitioners can use our findings to make OGD portals more inclusive and thus contribute to attaining key OGD policy objectives.@en
