Trusted Repositories

Journals and institutions have assessed a number of trusted repositories:

NOT ACCEPTABLE

A variety of (unfortunately) commonly used web-accessible locations are not acceptable as data repositories for the purpose of an article’s supplementary materials:

Some examples

Challenges in Hosting of Data and Code at Restricted-Access Data Centers

Users of restricted-access data centers (RADC, such as FSRDCs, CASD, etc.) face certain challenges in the handling of data and code as described in this document:

A few guidelines

Self-generated repositories

If a RADC has at least an archival or backup policy of sufficient length (e.g., 10 or more years), but does not offer a formal repository, then the following procedure allows users to find and request code and data
