Semantic validation of environmental observations data Environmental Modelling and Software.
In this paper, we focus on one such language, the Water Data Transfer Format (WDTF), and present an approach for validation of WDTF data contents. We show that by using Semantic Web technologies, we can express those constraints not captured by WDTF and check their consistency with respect to data through a query reduction technique that allows existing reasoners to be used for data validation.
