针对公共嗅觉记录中元数据完整性误导的问题，提出以可比性为核心的测量框架，通过四级阶梯和交叉映射操作，量化并恢复挥发性与感知数据间的可连接性，并发布一致性账本。
AI 中文摘要
研究数据基础设施衡量元数据的完整性，即已填充字段的比例。但这是错误的度量：一个已填充的字段并不一定是可连接的字段。我们转而衡量可比性：即两条记录能否一起使用，以及用于什么目的。基于八个公共来源的180,877条记录，我们将心理测量学中的测量不变性调整为四级阶梯，每一级由各自的测试确立，并许可一种特定的比较。在一个公共代谢组学存储库中，所有167,331对气相色谱分析中，100%达到最底层，58.85%达到第二层，0.072%达到第三层，恰好有两对达到许可直接比较数值的层级，这是在宽松测试下的上界。这一缺陷是可恢复的：缺失的值以散文形式存续。我们将交叉映射形式化为五种按可靠性排序的操作，每种操作都有其特有的失败模式。在第二个存储库的355项气相色谱研究中，决定保留时间的温度程序均未结构化，但78.6%以散文形式书写；我们恢复了206个有序程序，包含529个步骤，并经过三轮审计。感知记录则以不同方式失败：其数据集不共享语言。在八个声明测量人类气味特征的数据集中，42.9%的对没有共享描述符，而两项研究对相同分子使用相同词汇评分的平均相关性为0.31。将挥发性测量与人类感知在整个公共记录中连接，产生132个分子。在地震学、气象学、计量学和化学领域，当主要消费者没有该字段就无法完成主要任务时，该字段才被视为已填充：同一个可选、未验证的字段在一个学科中为100%，在另一个学科中接近零。资源应发布一致性账本，将缺失作为跟踪量报告；我们发布了一个包含48,356个三元组的账本。
英文摘要
Research data infrastructure measures metadata completeness, the share of fields populated. This is the wrong quantity: a populated field is not a joinable field. We measure comparability instead: whether two records can be used together, and for what. Working from 180,877 records across eight public sources, we adapt measurement invariance from psychometrics into a four-rung ladder, each rung established by its own test and licensing one specific comparison. Over all 167,331 pairs of gas chromatography analyses in a public metabolomics repository, 100% reach the bottom rung, 58.85% the second, 0.072% the third, and exactly two pairs reach the rung that licenses comparing values directly, an upper bound under a generous test. The deficit is recoverable: the missing values survive in prose. We formalise crosswalking as five operations ordered by reliability, each with a characteristic failure mode. The temperature programme that determines retention is structured in none of a second repository's 355 gas chromatography studies yet written in prose in 78.6%; we recover 206 ordered programmes comprising 529 steps, audited over three rounds. The perceptual record fails differently: its datasets do not share a language. Among eight that declare they measure odour character in humans, 42.9% of pairs share no descriptor, and two studies rating the same molecules with the same word agree at mean correlation 0.31. Joining volatility measurement to human percept across the entire public record yields 132 molecules. Across seismology, meteorology, metrology and chemistry, a field is populated when the primary consumer cannot complete the primary task without it: the same optional, unvalidated field sits at 100% in one discipline and near zero in another. Resources should publish a conformance ledger, reporting what is missing as a tracked quantity; we release one, with 48,356 triples.
