      Research and application of unstructured metadata management based on common model technology

      摘要:
      随着信息化和数字化在电网领域的不断发展,非结构化数据在电网信息总量中所占的比例越来越大,同时在很多电网数据业务应用中对非结构化元数据的管理缺乏统一性.为了提高元数据管理能力和数字资产的利用率,该文提出一种基于公共模型技术的非结构化元数据管理技术,对非结构化元数据资源进行梳理,建立数据关联模型,设计出一种合理的非结构化元数据管理方法.通过实际应用,证明了该方法的实用性和有效性.
      Abstract:
      With the continuous development of digital information in the field of power grids, the pro-portion of unstructured data in the total amount of information is increasing. At the same time, there is a lack of uniformity in the management of unstructured data in many applications. In order to improve the a-bility of data management and the utilization ratio of digital assets,in this paper, an unstructured metadata management technology based on common model technology is proposed. The unstructured metadata re-sources are sorted out, and the corresponding model is designed. A reasonable unstructured metadata management method is designed. In order to protect the security of data, an encryption algorithm is pro-posed. The feasibility and practicability of the method are proved by the application.
