Please note that the FREYA Knowlegde Hub has moved to become part of the PID Forum at
This website is therefore not being updated anymore. Rather you can find the most recent content on the Knowlegde Hub of the PID Forum:

Welcome to the FREYA Knowledge Hub, the Persistent Identifier (PID) Platform.

The Knowledge Hub is designed to help people understand what persistent identifiers are, why they exist, and how to use them for research. It began with FREYA's predecessor, the THOR project, and is continually being updated.

You'll find comprehensive guides and webinars to help you start working with persistent identifiers as quickly as possible, and there’s support if you get stuck. If you’re new to PIDs, start with our introduction then move on to the section most relevant to you.
