Open-Science Platform for Computational Materials Science: AiiDA and the Materials Cloud

We discuss here our vision for an Open-Science platform for computational Materials Science. Such a platform needs to rely on three pillars, consisting of 1) open data generation tools (including the simulation codes, the scientific workflows and the infrastructure for automation and provenance-tracking); 2) an open integration platform where these tools interact in an easily accessible way and computations are coordinated by automated workflows; and 3) support for seamless code and data sharing through portals that are FAIR-compliant and compatible with data-management plans. As a practical implementation, we show how such a platform in a few examples and focusing in particular on the combination of the AiiDA infrastructure and the Materials Cloud web portal.
