“…For instance, Nayek (2018) evaluated metadata quality of six national OGD sites, whereas Kubler and their colleagues (Kubler, Robert, Neumaier, Umbrich, & Le Traon, 2018) established an Analytic Hierarchy Process (AHP) for comparing and ranking sites for the quality of their metadata from a usercentered perspective. In addition, there are notable studies that compared the content and features of US municipal OGD sites (Thorsby et al, 2016), developed 30 criteria for evaluating e-government services (Sá, Rocha, & Pérez Cota, 2016), created a framework for measuring OGD quality and applied it to two Italian datasets (Vetro et al, 2016), evaluated the effectiveness of platforms for promoting transparency (Lourenço, 2015), and presented (but did not apply) a framework to measure the overall quality of national OGD sites (Ubaldi, 2013).…”
