Metadata management is an essential condition to follow the FAIR principles. Therefore, metadata management was one asset of an accompanying project within a funding scheme for registries in health services research. The metadata of the funded projects were acquired, combined in a database compatible with the metamodel of ISO/IEC 11179 "Information technology - Metadata registries" third edition (ISO/IEC 11179-3), and analyzed in order to support the development and the operation of the registries. In the second phase of the funding scheme, six registries delivered a complete update of their metadata. The mean number of data elements increased from 245.7 to 473.5 and the mean number of values from 569.5 to 1,306.0. The conceptual core of the database had to be extended by one third to cover the new elements. The reason for this increase remained unclear. Constraints from the grant might be causal, a deviation from an evidence-based development process as well. It is questionable, whether the revealed quality of the metadata is sufficient to fulfill the FAIR principles. The extension of the metamodel of ISO/IEC 11179-3 is in agreement with the literature. However, further research is needed to find workable solutions for metadata management.
元数据管理是遵循 FAIR 原则的必要条件。因此，元数据管理是卫生服务研究注册登记资助计划中伴随项目的一项资产。获取了资助项目的元数据，将其组合到一个与 ISO/IEC 11179“信息技术-元数据注册登记”第三版（ISO/IEC 11179-3）元模型兼容的数据库中，并进行了分析，以支持注册登记的开发和运行。在资助计划的第二阶段，六个注册登记处提供了其元数据的完整更新。数据元素的平均数量从 245.7 增加到 473.5，值的平均数量从 569.5 增加到 1306.0。数据库的概念核心必须扩展三分之一，以涵盖新的元素。这种增加的原因尚不清楚。拨款的限制可能是原因，也可能偏离循证开发过程。值得怀疑的是，所揭示的元数据质量是否足以满足 FAIR 原则。ISO/IEC 11179-3 元模型的扩展符合文献。然而，需要进一步研究以找到可行的元数据管理解决方案。
