Abstract: Visual analytics requires the use of large datasets and most of the times visualisations use their own data structures definition or make use of simple standards such as XML, CVS, or text files. Our proposal presents a middleware framework that focuses on providing a way to create those data structures, allowing to access heterogeneous data sources. The framework allows defining data structures for different visualisations using the same dataset as well as makes easier the process of getting the data from different sources. It dynamically creates the objects according to the defined structures and populates them with the values in the data sources. We have implemented a first prototype, which is discussed in the results presented on this paper.
