FAIRsharing record for: FAIR Metrics - Metadata Longevity

This FAIRsharing record describes: 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.

本FAIRsharing记录描述：FM-A2指标用于衡量数据缺失或移除时元数据的存在性。第三方FAIR数据与元数据中对数据的交叉引用会随时间自然退化，成为“失效链接（stale links）”。在此情况下，FAIR数据提供者需持续提供数据描述信息，以助力第三方数据的后续解读，这一点至关重要。依据FAIR原则F3（FAIR Principle F3），即便数据缺失，此类元数据仍具有可发现性，原因在于其包含对数据IRI（IRI）的明确引用。该指标要求提供指向正式元数据长期保存计划的URL链接。此指标适用于FAIR原则的A2部分。
