Web data management

Research at Charles University

One of the goals of our research is to highlight problems with data interoperability and data management and establish a data-centric ecosystem where ontologies play a primary role and all other technical artifacts such as data models, data schemas, data collection forms, data transformations, and even simpler data visualization applications are automatically generated based on the ontological description of the problem domain. Our approach focuses not only on the technical solutions of the problem but also on procedural and social aspects of the problem, as novel approaches need to be explained to and accepted by the target audience – data owners. Technically, our approach includes working with semantic technologies and linked data and we focus on making correctly published data consumable as easily as possible by as many data consumers as possible, ensuring adoption of the approach.

Our approach already gained interest from institutions in the Czech public administration, who had the possibility of trying it out and liked it. Now we intend to extend the approach to the Europan level and improve our technical solutions.
