Demystifying Data Standards: A Guide to MCPD 2.1

· 3 min read

When we talk about plant genetic resources for food and agriculture (PGRFA), the word "data" can feel a bit overwhelming because it means different things to different people. For one person, "Collection Site" might be the go-to term, while someone else prefers "Origin." Without a shared language, sharing information between genebanks can easily become a confusing tangle of spreadsheets and guesswork.

That is where the Multi-Crop Passport Descriptors (MCPD) 2.1 come in.

What exactly is MCPD?​

Developed through a partnership between Bioversity International and the FAO, MCPD 2.1 is the standard for exchanging passport information. You can think of it as a universal "passport" for every plant genetic resource (PGR) in a genebank. It makes sure that no matter where a sample originates, its core identity (who collected it, where it was found, and what it is) is recorded in a way that everyone understands.

The Key Pillars of the Standard​

If you're exploring an MCPD record, there are a few fields that really do the heavy lifting:

  • PUID (Persistent Unique Identifier): In Genesys, we rely on DOIs. A PUID is a digital fingerprint that lets a researcher in Japan and a curator in Brazil be sure they are talking about the exact same accession.
  • SAMPSTAT (Biological Status): Is it a wild relative, a landrace, or a breeding line? Knowing the biological status helps us put all the other data into the right context.
  • ORIGCTY (Country of Origin): To keep things crystal clear, we use ISO 3-letter codes. This avoids any mix-ups between "USA", "United States", and "U.S.A."

Why bother with standardization?​

We know that following strict formatting rules (like using YYYYMMDD for dates) can feel like a chore, but the benefits are worth it:

  1. Better Searchability: You can search across hundreds of collections simultaneously because the data is predictable and consistent.
  2. Seamless Interoperability: Your data can move effortlessly between Genesys, EURISCO, and the World Information and Early Warning System on Plant Genetic Resources for Food and Agriculture (FAO WIEWS).
  3. Future-Proofing: Standards keep your data relevant and usable, even as technology evolves.

Ready to dive in?​

For genebanks looking to join the Genesys community, adopting MCPD 2.1 is a strong first step toward gaining global visibility. We are here to help you with the tools and guidance needed to map your existing data to these descriptors, transforming your internal archives into a valuable global resource.
