ready FAIR Metrics - Metadata Longevity

Abbreviation: FM-A2

General Information
FM-A2 measures the existence of metadata even in the absence/removal of data. Cross-references to data from a third-party’s FAIR data and metadata will naturally degrade over time, and become “stale links”. In such cases, it is important for FAIR providers to continue to provide descriptors of what the data was to assist in the continued interpretation of those third-party data. As per FAIR Principle F3, this metadata remains discoverable, even in the absence of the data, because it contains an explicit reference to the IRI of the data. This metric requires a URL to a formal metadata longevity plan. This metric applies to part A2 of the FAIR Principles.
