About this tool

How it works

You answer questions about your data, such as its kind, who funds it and whether it can be open; each answer leads to the next question, and you can go back or skip to the results at any time. The results list the repositories that fit your answers so far: a repository is left out when it contradicts an answer, the others are ordered, with the repositories for your kind of data first, by points and by how much chemistry they cover: one point for each answer a repository supports, one for training material of FAIR4ChemNL about it, and one when a service of NFDI4Chem, NFDI4Cat or ELIXIR offers it, and for what is not known about a repository nothing is assumed. Open a repository to see what is known for each question.
