摘要

元数据表示一组关于数据的描述性信息，旨在促进数据的搜索、访问和使用。元数据标准规定了要通知的最小元素集和文件结构，以确保目录之间的互操作性。本工作旨在通过一致性指标分析巴西空间数据基础设施（SDI）存储库中发布的元数据与MGB档案（葡萄牙语为Perfil de Metadados Geoespaciais do Brasil）的一致性。2018年6月，考虑到MGB概要的一组强制性和条件性元素，对插入INDE目录（葡萄牙语为Infrastrutura Nacional de Dados Espacais）的30000多个元数据的一致性进行了评估。这些元素是从作者精心设计的采集器中收集的，该采集器能够扫描存储库的所有元数据并返回组织到CSV文件中的字段。经过分析，发现只有28%的元数据符合MGB概要。低符合率表明，对推荐标准的理解有限，既涉及每种产品的最低元素，也涉及XML信息的结构。

INDE METADATA CONFORMITY INDICATOR

Metadata represents a set of descriptive information about the data, which aims at facilitating the search, access and use of data. The metadata standards specify the minimum set of elements to be informed and the file structure to ensure interoperability among catalogs. The present work aims at analyzing the adherence of the metadata published in the Brazilian Spatial Data Infrastructure (SDI) repository to the MGB Profile (in Portuguese, Perfil de Metadados Geoespaciais do Brasil) through a conformity indicator. Conformity was evaluated for over 30,000 metadata inserted in the INDE catalog (in Portuguese, Infraestrutura Nacional de Dados Espaciais), in June 2018, considering the set of mandatory and conditional elements of the summarized MGB Profile. These elements were collected from a harvester elaborated by the authors capable of scanning all the metadata of the repository and returning the fields organized into a CSV file. After analysis, it was found that only 28% of metadata conforms to the summarized MGB Profile. The low conformity rate suggests the limited understanding of the standards recommended, regarding both the minimum elements to be informed about each product and the structuration of the information in XML.
