【摘要】 材料科学大数据的规范化工作是材料科学数据全生命周期管理的重要环节。文本针对材料科学数据的多源异构特性,提出了材料科学数据的统一描述规范,根据数据产生形态分别对数据结构进行约束。同时,我们将此描述规范成功应用于国家材料科学数据共享网新版本建设中,对数据采集、数据存储和数据检索功能进行了优化,在材料科学数据资源汇交和管理过程中具有广泛适用性。更多还原

【Abstract】 Normalizationof materials scientific big data shows extraordinary significance for its whole life-cycle management. Based on the multi-source and heterogeneous features of materials scientific data, we establish the uniform description specification in this paper. We define corresponding data structure according to different data production pattern. Meanwhile, we apply this specification to the new version construction of National Materials Scientific Data Sharing Network, and optimize the function of datacollection, data storage and data retrieve. It has wide applicability in the process of data curation of multidisciplinary materials science.更多还原
