中文摘要:
      元数据注册(Metadata Registry,MDR)是数据治理中元数据精确表达语义的必要前提。通过全面系统地分析国内外的MDR系统,发现国内外MDR更多关注基本数据元素,数据语义约束注册方面的研究缺乏。因此,首先基于ISO/IEC 11179:2023(MDR2023)系列标准提出元数据语义约束外延分类模型,明确元数据语义约束范围,并选取其中的值域语义约束详细研究;其次,基于MDR2023标准提出元数据值域语义约束注册元模型,为元数据语义约束注册提供标准化且完整的注册算法流程,从而为元数据值域语义约束注册提供解决方案;最后,以石油领域著名的POSC标准为需求背景,对其中的值域语义约束进行注册,据此实现石油领域元数据值域语义约束的标准化,验证提出的元数据值域语义约束注册元模型的合理性和可行性。提出的元模型对于其他领域数据治理具有普适性。
英文摘要:
      Metadata registry (MDR) is a necessary prerequisite for the precise expression of semantics in metadata during data governance. This paper conducts a systematic analysis of MDR systems both domestically and internationally, finding that MDR focuses more on the registration of basic data elements, and there is a lack of research in the area of data semantic constraint registration. Therefore, this paper first proposes a metadata semantic constraint extension classification model based on ISO/IEC 11179:2023 (MDR2023) standards, clarifies the scope of metadata semantic constraints, and selects the value domain semantic constraints for detailed study. Secondly, the metadata value domain semantic constraint registration metamodel is proposed based on MDR2023 standards, providing a standardized and complete registration algorithm process for metadata semantic constraint registration and a solution for registering metadata value domain semantic constraints. Finally, with the famous POSC standard in the petroleum field as the demand background, the value domain semantic constraints are registered, thereby realizing the standardization of the value domain semantic constraints of the metadata in the petroleum field, and verifying the rationality and feasibility of the metadata value domain semantic constraint registration metamodel proposed in this paper. The metamodel proposed in this paper is generalizable to other domains of data governance.
