During the last decades, interdisciplinarity has become a central keyword in research. As a consequence, many concepts, theories and scientific methods get in contact with each other, resulting in many different strategies and variants of acquiring, structuring, and sharing data sets. To handle these kind of data sets, his paper introduces the Ariadne Corpus Management System that allows researchers to manage and create multimodal corpora from multiple heteogeneous data sources. After an introductory demarcation from other annotation and corpus management tools, the underlying data model is presented which enables users to represent and process heterogeneous data sets within a single, consistent framework. Secondly, a set of automatized procedures is described that offers assistance to researchers in various data-related use cases. Thirdly, an approach to easy yet powerful data retrieval is introduced in form of a specialised querying language for multimodal data. Finally, the web-based graphical user interface and its advantages are illustrated.
