This is a growing, curated collection of publicly available training materials, handbooks, cookbooks, documentation, and guides focused on persistent identifiers (PIDs) — both in general and for specific PID systems and providers.
The resources originate from various institutions and initiatives and are not maintained by us. As a work in progress, this overview will evolve to reflect the needs of the NFDI research communities. Suggestions are welcome.
Fundamentals, significance, and an overview of the PID ecosystem. Includes beginner-friendly introductions, insights into governance, and the conceptual role of PIDs in research infrastructure.
This introductory presentation offers a clear and engaging overview of persistent identifiers (PIDs) — what they are, how they work, and why they matter. It explains how PIDs uniquely and permanently identify people, places, and research outputs, supporting interoperability, discovery, and FAIR data. With practical examples from ORCID, ROR, DataCite, and Crossref, it shows how connected PIDs create a trustworthy and transparent research ecosystem (EN)
