Abstract
A persistent dataset address can resolve successfully while no longer providing the evidence used in a published calculation. This methods note compares FORCE11 citation principles, DataCite versioning guidance, and Research Data Alliance recommendations for evolving data. A fictional index revision separates corrected observations from expanded coverage and demonstrates why collection identifiers, release identifiers, subsets, and analysis outputs answer different questions. The discussion examines immutable releases, timestamped queries, stable sorting, checksums, and persistent landing pages without presenting any one repository design as mandatory. It distinguishes exact reproduction from scientific robustness and explains why reproducibility does not override legitimate restrictions. The resulting recommendation is a compact citation backed by recoverable authorised evidence and an inspectable method, with explicit limits when retrieval becomes impossible.
