OGD metadata country portal publishing guidelines compliance: A multi-case study search for completeness and consistency

To guarantee a certain level of data usability, metadata which is information about the OGD, is needed. For this reason, OGD administrators provide metadata publishing guidelines to request, among other things, that certain metadata field always be present (completeness) and that field validation rules, when provided, be met (consistency). Lack of compliance of OGD metadata with publishing guidelines in country portals constitutes poor metadata quality control and will drastically decrease the effective use/reuse of the data and keep the expected benefits from being realized. This study explores the extent of metadata compliance, in terms of completeness and consistency, of three OGD leading country portals (Canada, USA, New Zealand) with respect to their own metadata publishing guidelines. A statistical comparison of population proportions among the countries was performed. The results indicate that the compliance of the USA is far less than Canada and New Zealand in terms of datasets with required fields set (completeness). On the other hand, New Zealand trails Canada and the USA in terms of OGD datasets with valid (consistent) fields. These results indicate that OGD metadata compliance is rather poor, suggesting insufficient quality control. Finally, this study concludes with suggestions to improve the OGD platforms so that metadata compliance can be automatically enforced.
