Analysis of the Landscape of Repositories for Chemistry in re3data

In Summer 2023, we carried out an analysis of repositories for chemistry data in re3data. When applying the filters “Chemistry” and “Worldwide” 252 repositories were listed. Subsequently, additional filters were applied: after filtering for “Database Access: Open”, 220 repositories remained, after applying “Content Types: raw data”, 100 repositories were displayed and finally, only 98 repositories resulted after applying the filter “Repository Languages: English”.
However, we quickly realised that while the repositories provided raw data, the ingestion of these raw data was not possible or only possible for a selected group of users (e.g. for institutional repositories). Re3data does not currently provide a field that allows it to filter for repositories that allow ingestion of data submitted by anyone in the world.
We were therefore forced to apply the following filters manually:

● Ingestion of raw data possible
● Submission of raw data not restricted to a selected group of users (i.e. open to anyone)
● Submission possible independent of the country of origin

After applying these two filters manually, only 12 repositories remained (see the table in the document).

Of these 12 repositories, 7 are part of the NFDI4Chem federation.

Concluding, NFDI4Chem currently provides a valuable service to the chemistry community (at least according to the re3data analysis) with few alternatives and for specific data types, there are, at the moment, no other options to the repositories included within the NFDI4Chem federation.
