Kadi4Mat, or Kadi for short, is a generic and open source virtual research environment. Originally developed in the context of materials science, Kadi4Mat can be used for the management of any type of research data within different research disciplines and use cases. Kadi4Mat is being developed as part of several research projects at the Karlsruhe Institute of Technology (KIT).

The goal of Kadi4Mat is to combine the ability to manage and exchange data, the repository component, with the possibility to analyze, visualize and transform said data, the electronic lab notebook (ELN) component. The focus on the repository component is on warm data, i.e. unpublished data that is yet to be analyzed further, while in the ELN component it is on the automated and documented execution of heterogeneous workflows via an application programming interface (API). In this way, a customizable framework is created that facilitates good research data management practices and collaboration between researchers.
