This episode demystifies metadata by explaining how it transforms "mystery jars" of data into independently understandable assets that comply with the 2021 Tri-Agency RDM policy. We break down the four metadata buckets—descriptive, administrative, structural, and provenance—that underpin the FAIR principles and ensure your research is findable and reusable. Finally, we share a practical action plan to avoid the "seven deadly sins" of data management: document your work in the moment and consult your university’s RDM librarian.
