【摘要】：跨领域数据共享是当今信息化建设的重要研究热点之一,数据交换是实现数据共享的重要方式,而数据交换成功的基本前提是交换双方必须遵循共同的标准。虽然国内乃至国际上各领域已经制定了诸多的相关数据交换标准,但是随着跨领域数据交换需求的日益复杂化,对数据共享的要求也随之越来越高,已有的数据标准已不能满足当前的复杂的、多变的数据共享需求现状。对于所有需要交换的数据,在实际应用中如果我们均定义成公共标准是不太切合实际的,甚至可以说是不可能的。为解决以上问题,本文对数据交换与共享理论及技术进行充分的研究,并对当下复杂的数据共享的需求进行分析。基于“自标准”概念,并借鉴NIEM(National Information Exchange Model,美国国家信息交换模型)的实现方法,通过已有标准和自标准相结合,并将数据模式的概念引入到数据模型中,采用XML Schema语言对其进行描述,构建了由公共数据模型、业务领域数据模型及编码表构成的数据模型库以实现数据自标准化;并对数据港口技术架构运行和数据管理机制进行了详细规划,其中包括基于11179-MDR(Metadata Registry,元数据注册)-数据集元数据注册规范提出的港口数据集元数据注册元模型,为实现软件之间的互操作对应生成元数据,用其描述数据的语义和语法,并提出了数据集资源分类与编码方法和基于老化算法改进的码头数据清理方法。最后,为实现自标准数据的共享,提出了基于自标准数据和数据港口技术架构的数据共享模型的构建方法,通过建立初始业务模型,经过映射、扩充数据模型以构建完整的数据共享模型。依照共享模型生成数据交换包,通过验证、加密、压缩等步骤,接入Web服务实现数据共享。为验证所提出的基于自标准与数据港口技术架构的数据共享模型具有有效性和技术可行性,以油田数据为背景初步设计并且实现了原型系统。这些研究成果为跨领域、跨学科的数据共享奠定了初步的基础。
[Abstract]:Cross-domain data sharing is one of the most important research hotspots in information construction nowadays. Data exchange is an important way to realize data sharing. The basic premise of the success of data exchange is that both sides must follow the same standard. Although many related data exchange standards have been established in domestic and international fields, with the increasing complexity of cross-domain data exchange requirements, With the increasing demand for data sharing, the existing data standards can no longer meet the current complex, volatile data sharing requirements. For all the data to be exchanged, In practical application, it is not practical or even impossible to define public standards. In order to solve the above problems, the theory and technology of data exchange and sharing are fully studied in this paper. Based on the concept of "self-standard" and using the method of NIEM(National Information Exchange Model for reference, this paper combines the existing standards with self-standards. The concept of data schema is introduced into the data model and described by XML Schema language. The data model base composed of common data model, business domain data model and coding table is constructed to realize data self-standardization. In addition, the operation and data management mechanism of data port technology architecture are planned in detail, including the port data set metadata registration metadata metadata model based on 11179-MDR metadata registration specification. In order to realize the mutual operation of software to generate metadata, the semantics and syntax of the data are described, and the classification and coding method of data set resources and the improved method of data cleaning based on aging algorithm are proposed. In order to realize the sharing of self-standard data, a method of constructing data sharing model based on self-standard data and data port technical architecture is proposed. Expand the data model to build a complete data sharing model. According to the sharing model to generate data exchange packages, through verification, encryption, compression and other steps, To verify the validity and technical feasibility of the proposed data sharing model based on self-standard and data port technology architecture, The prototype system is designed and implemented in the background of oilfield data, which lays a foundation for cross-domain and interdisciplinary data sharing.
