OPEN DATA REUSE IV
• Clear strategies for the development of the sector in Spain. There is still a need for a clear strategy for portals to improve their usage expectations. In this case it is advisable to use open innovation to better understand the needs of reusers so that data can be published in a way that better meets their expectations. • Unique identifier of datasets. Data federation facilitates the republication of datasets across different portals. There are already initiatives to develop a unique identifier (Ortiz de Urbina Criado, Abella and García Luna, 2023) and specific mechanisms to identify federated datasets that can help to make better use of said datasets. • Pretender portals. 43.02 % of open data portals still have minimal reusability features, a very low number of datasets and extreme difficulties for interacting with portal managers.
• Data standardisation. 69.90 % of the published data does not follow an international model, nor do they publish their own data model, and none follow an international standard. • Commitment to data spaces. Open data portals have to be integrated as the primary data sources for data spaces, which are widely promoted in the European Union; but the technical tools to make this connection are not yet available. • Developing data governance. This would allow for the integration of internal data sources and their systematic publication with low impact on the organisation. This could improve the use of data models, publication frequencies, data geolocation and overall data quality.
