The prototype of the Data Map application was developed as part of a pilot project of the same name in cooperation with the OPSI portal (Slovenia Open Data Portal) and is an extension of the OPSI catalogue of public sector information. The Data Map provides an enriched understanding of data sources and the data they contain. The Data Map helps to understand how data are interlinked, their meaning, the refresh rate, etc., and it allows for an overview and exploration of the data structures of the data sources as well. It is designed to facilitate the exploration, discovery and access to data sources that are further used, for example, to design public services and other tools and applications for public administrations, citizens and businesses.
The tool provides a general overview of the data landscape based on descriptions of data sources according to semantic standards (RDF-based), allowing inter-comparability and interoperability. The overview is provided in a form of a graph, allowing the user to efficiently and transparently search for related data across sources. In addition to the overview of the global schema of the Data Map, which contains all types of description categories and properties used to describe the datasets in the Data Map, it also allows the overview of the schemas of selected sources and data structures (the available data model).
Citizens, companies and organisations are interested in the data as end-users and can freely use the published data or check the conditions for access and use of other protected public sector information. In this way, we aim to strengthen interoperability between public administrations and encourage the use of data for commercial, non-commercial or research purposes.
