Research data and publications Another idea is that research data repositories, OER repositories or publication repositories could be connected to Fediverse via Activity Pub. Each item of such a database would then be easily commented and shareable. Additionally, each reference to this item could be listed below it in the respective repository. You can imagine this as if every PID or DOI had a kind of inbox, in which a notification appears whenever someone references it. Perhaps this will yield new (more transparent?) metrics for measuring outreach and citations, which are praised and criticized in equal measure in the scientific community.
