【摘要】：在过去几十年的信息建设中,石油企业构建了许多应用系统,但这些系统之间却很难实现彼此的互操作,进而导致了大量“信息孤岛”的产生,数据元的出现为这一问题的缓解带来了生机。国内外学者一直试图以元数据注册为理论指导,解决信息的交换与集成问题,虽然也取得了较好的效果,但元数据注册系统(Metadata registries,MDR)本身的局限性导致概念并没有系统的组织在一起,给使用MDR的企业也带来了一定的困扰。为了解决以上问题,本文以国际标准化组织及国际电工委员会联合发布的最新元数据注册标准(ISO/IEC 11179-3:2013)为核心,借鉴了现阶段数据元理论的部分成果,构建了MDR概念体系,规范了概念的语义,为MDR和数据元目录中概念的组织与共享提供了强有力的理论支持,具体的研究内容如下:1.MDR概念体系的构建。根据最新版本元数据国际标准中的相关内容,提出了元数据注册框架模型。通过阐述模型中各层的内容和联系,明确了MDR中概念的组成结构,并通过MDR概念元模型将这些概念关联在一起,这种概念以及概念之间的关系就构成了MDR概念体系。2.MDR概念体系的表示。为了更好的对MDR概念体系进行表示,采用XML和知识本体两种表示方式。在XML表示中,通过制定概念的XML Schema,明确了MDR概念体系的结构化表示流程;在本体的表示中,提出了MDR本体转换框架,实现了MDR概念体系到本体的转换。3.数据元标准化框架模型。MDR中有诸多种概念,这些概念可以共同构成数据元,通过对数据元生命周期的划分,提出了数据元标准化框架模型。在模型中研究了数据元提取的方法,规范了数据元的四类属性,并针对数据元的特点给出了MDR的应用。4.勘探开发数据元目录的构建。为了合理的对数据元进行组织,明确了数据元目录的构建流程,并提出了对象类、特性、表示类、业务的数据元分类方案,将数据元目录的构建方法与勘探开发业务相结合形成了满足于不同应用的勘探开发数据元目录,并对勘探开发领域数据元分类方案的部分结果进行了展示。最后,为了对本文提出的元数据注册相关理论进行验证,从软件工程的角度出发,对勘探开发元数据注册平台进行了详细设计和功能实现,从而证明了本文研究内容的合理性及可行性。
[Abstract]:In the past decades of information construction, petroleum enterprises have built many application systems, but these systems are difficult to achieve mutual operation, which leads to a large number of "information isolated islands".The emergence of data elements has brought life to the relief of this problem.Domestic and foreign scholars have been trying to solve the problem of information exchange and integration under the guidance of metadata registration.However, the limitations of metadata registration system (MDR) itself lead to the lack of systematic organization of the concept, which also brings some troubles to enterprises using MDR.In order to solve the above problems, this paper takes ISO / IEC11179-3: 2013, the latest metadata registration standard jointly issued by the International Organization for Standardization and the International Electrotechnical Commission, as the core, and draws lessons from some achievements of the current data element theory to construct the conceptual system of MDR.The semantics of the concept is standardized, which provides a strong theoretical support for the organization and sharing of concepts in MDR and the data element catalog. The specific research contents are as follows: 1. The construction of the concept system of MDR.According to the relevant contents of the latest version of the international standards of metadata, a metadata registration framework model is proposed.By expounding the contents and connections of each layer in the model, the composition and structure of the concepts in MDR are clarified, and these concepts are connected together by the MDR concept metamodel.This concept and its relationship constitute the representation of MDR conceptual system.In order to better represent the concept system of MDR, XML and knowledge ontology are adopted.In the XML representation, the structured representation flow of the MDR conceptual system is defined by making the concept XML Schema, and in the ontology representation, the MDR ontology transformation framework is proposed, which realizes the transformation from the MDR conceptual system to the ontology.There are many concepts in data element Standardization Framework Model (MDR), which can form data element together. By dividing the life cycle of data element, a data element Standardization Framework Model is proposed.The method of data element extraction is studied in the model, the four kinds of attributes of data element are standardized, and the application of MDR is given according to the characteristics of data element.Construction of data element catalogue for exploration and development.In order to organize the data element reasonably, the construction process of the data element catalog is clarified, and the data element classification scheme of object class, characteristic, presentation class and business is put forward.Combining the construction method of data element catalogue with exploration and development business, the exploration and development data element catalogue is formed, and some results of data element classification scheme in exploration and development field are presented.Thus, the rationality and feasibility of this paper are proved.
