Kadi4Mat supports a close cooperation between experimenters, theorists and simulators, especially in materials science, to ultimately enable the acquisition of new knowledge and the development of novel materials. This is made possible by employing a modular and generic architecture, which allows to cover the specific needs of different scientists, each utilizing unique workflows. At the same time, this opens up the possibility of covering other research disciplines as well.

The focus on the repository component is on warm data, i.e. unpublished data that is yet to be analysed further, while in the ELN component it is on the automated and documented execution of heterogeneous workflows via an application programming interface (API). The components are therefore best described as community repository and ELN 2.0 respectively. In this way, a virtual research environment and framework is created that facilitates collaboration between researchers. The long-term goal of Kadi4Mat is the ability to electronically record the entire scientific workflow of daily research work by combining its own solutions with existing concepts and systems.
