Meta data management is the process for managing information needed to promote data legibility , use and administration . contents are described in terms of data about data , activity and knowledge 元数据管理是提供数据可理解、使用和管理的管理信息的过程。主要用来记录数据、行为和知识。
At the same time , it will promote actively the sharing and network issue of geo - spatial information . it also has far - reaching social meaning . at last , we apply the register of the system designed by us to fgdc 最后我们将所设计的空间信息元数据管理系统向fgdc申请注册,并且将该节点发布到internet上,任何单位和个人都可以通过www浏览器访问我们的元数据。
Therefore , i was quite disappointed to see so many of the xml process initiatives reinvent the rdf wheel . but as i noted in a developerworks article the web services description language wsdl , all too many xml applications overlook rdf s strengths 它能帮助人们了解半结构化关系和元数据管理的价值,因此这简直是恩赐,因为向生意人甚至许多开发人员解释这一概念都不是一件容易的事。
So , we depicted the content management system from different aspects , and pointed out the core issues about metadata management , xml interface form , and process management and etc . we also gave an instance of cms to explain the concepts above 文章据此对相关的内容管理系统进行了刻画,并通过对一个影像系统实例的分析,指出了其中诸如元数据管理, xml接口形式,流程管理等关键的核心议题。
This paper outlines the key techniques of xml 1 . 0 , xml schema , xslt , xquery , which are related to the realization of the metadata management system . then deeply study the expression of metadata based on xml and the technology of transformation and search 论文重点介绍了与实现元数据管理系统有关的xml1 . 0 、 xmlschema 、 xslt和xquery等相关的关键技术;深入研究了基于xml的元数据表达、转换和查询技术。
And a solution scheme of management model on metadata in the digital city is put forward . on this basis technology of interoperation are suggested , including concepts , criteria and layer modeling . finally , a sharing mechanism of the data of city space is set up 接着,在对空间数据元数据的定义、分类、作用以及如何对元数据进行管理进行研究探讨后,提出了一个城市数字化中元数据管理模型的解决方案。
Xml schema , xslt and xquery . the metadata management must be performed according to its characteristics and the application ' s needs . this paper gives a total frame for the geospatial metadata ' s management system and function division of those modules toward their implementation 论文提出了一个空间元数据管理系统的总体设计框架,并围绕空间元数据库管理和检索功能的实现,给出了各系统模块的功能划分和概要设计方案。
According to the basic concept and theory of data warehouse , the present paper discusses on a few problems in the field of data warehouse in modeling , implementation , the analysis and integration of olap and especially on the management of metadata in data warehouse 本文从数据仓库的基本概念与理论出发,讨论了数据仓库领域中有关建模、实施、 olap分析与集成的许多问题,重点对数据仓库中的元数据管理这一热点问题进行了研究。
With the development of information and separation between the production department and the application department , the data sharing has been one of the important purposes of the construction of information fundamental facilities . among that , metadata management is the key to facilitate the sharing 随着信息化的发展和数据生产部门与应用部门的分离,数据共享成为信息基础设施建设的重要目标之一,其中元数据管理系统是实现数据共享的关键所在。
