Experience and feedbacks from the sustainability for the virtual atomic and molecular data centre E-infrastructure

VAMDC is a worldwide E-infrastructure, built on a European FP7 project, which federates interoperable Atomic and Molecular databases. The contained data are of the highest scientific quality and are crucial for many applications: astrophysics, atmospheric physics, fusion, plasma and lighting technologies, health, etc. In this paper we discuss the actions we are performing for sustaining this E-infrastructure. At first we will detail the political aspects we had to agree within the VAMDC consortium before we could effectively establish an external strategy. Then we will explain how these agreements are implemented in order to built a sustainable plan based on academic, industrial, education and citizen-outreach partnerships. As these actions are related to human and organisational aspects, our experience can be fruitfully transposed to other scientific E-infrastructures.
