The paper considers the problem of visualizing heterogeneous information relevant to the solution of a particular problem domain. An essential part of the task is to get the conversion of data objects doing their representation adjusted for the corresponding data model. Creation of model of converting of data objects is offered on the basis of applicative computing systems. Achievement of flexibility requires the parametrization of the considered construction, i.e. support of dependence of a set of available methods of interpretation on parameters as which semantic characteristics of processed data appear. The methods of working with interpretation coordination tools have been partially tested when implementing various applications for informational support for the implementation of the best available technologies (BAT).
