Empirical medical research needs services for the maintenance of item collections. We evaluated the appropriateness of ISO/IEC 11179 "Information technology - Metadata Registries (MDR)" part 3 "Registry Metamodel and basic attributes" for a national MDR. In particular, possibilities of including classifications and terminologies (summarized as vocabularies) using the metamodel of this standard were assessed. The hierarchical structure of classifications and terminologies could be mapped easily to ISO's metamodel. The Classification Markup Language (ClaML) is attractive as interface standard for the import of classifications into the MDR. The correct linkage between data elements and vocabularies remained unclear however. An extension of the ISO 11179 metamodel might be necessary to satisfy the predefined needs of a national MDR.
实证医学研究需要用于维护项目集的服务。我们评估了ISO/IEC 11179《信息技术——元数据注册库（MDR）》第3部分“注册库元模型和基本属性”对于国家MDR的适用性。特别地，评估了使用该标准的元模型纳入分类和术语（总结为词汇表）的可能性。分类和术语的层次结构可以轻松映射到ISO的元模型。分类标记语言（ClaML）作为将分类导入MDR的接口标准很有吸引力。然而，数据元素和词汇表之间的正确链接仍不明确。可能需要扩展ISO 11179元模型，以满足国家MDR的预定义需求。
