Open Government Data (OGD) has the potential to support social and economic progress. However, this potential can be frustrated if this data remains unused. Although the literature suggests that OGD datasets' metadata quality is one of the main factors affecting their use, to the best of our knowledge, no quantitative study provided evidence of this relationship. Considering about 400,000 datasets of 28 national, municipal, and international OGD portals, we have programmatically analyzed their usage, their metadata quality, and the relationship between the two. Our analysis has highlighted three main findings. First of all, regardless of their size, the software platform adopted, and their administrative and territorial coverage, most OGD datasets are underutilized. Second, OGD portals pay varying attention to the quality of their datasets’ metadata. Third, we did not find clear evidence that datasets usage is positively correlated to better metadata publishing practices. Finally, we have considered other factors, such as datasets’ category, and some demographic characteristics of the OGD portals, and analyzed their relationship with datasets usage, obtaining partially affirmative answers.
The dataset consists of three zipped CSV files, containing the collected datasets' usage data, full metadata, and computed quality values, for about 400,000 datasets belonging to the 8 national, 4 international, and 16 US municipalities OGD portals considered in the study.
Data collection occurred in the period: 2019-12-19 -- 2019-12-23.
