The article discusses the challenges of data discoverability, accessibility, and interoperability in the context of Open Data portals. It introduces a solution that combines NGSI-LD standard with CKAN-based Open Data portals to enhance data description and access. The proposed architecture involves multiple components like Form, Dataset Registry, Context Brokers, CKAN instance, Retriever module, and EDP connector. The validation scenario implementation showcases the successful integration of these components in a real-world use case involving the SALTED project and the European Data Portal (EDP). The solution aims to improve data quality assessment metrics such as Findability, Accessibility, Interoperability, Reusability, and Contextuality.
