Last week I gave a talk at the FREYA project wrap up meeting, part of the EOSC life symposium, on PIDs and how we (as part of my day job) were looking at using them to reproduce scientific research. This was one of the prize winners for the end of project award.

The basic concept is as follows:

  1. When a researcher visits an institution we create a PID identifying their “session”
  2. As an experiment is performed, we mint PIDs for each relevant asset, and “cite” the session identifier. Assets should include everything relevant for reproducing the science (this includes things you might not think of such as beam line or microscope configuration settings)
  3. When a research output is produced (research paper, protein in the protein database), all these sessions are tied together with another PID and a link is established between that bundle and the final output
  4. Using the PID Graph it is possible to unpack this.

If you’re interested, you can watch the presentation, or read more in the paper below.

This is just a quick one to say that I’ve spun out the Postgres database support out of Known core and into a community supported plugin.

The reason for this is basically that I want to put in some significant data model changes into Known core in the next few months, and due to my other commitments (and lack of Postgres expertise), I don’t have the resources to maintain this myself.

Anyone who’s interested in picking up Postgres support, please reach out in the comments or by email. I’ll also do my best to keep things up to date, but I’m unfortunately spread pretty thin these days!
