专门数字对象元数据元素设计

目前数字对象元数据有基本元数据集合标准,但对于许多特有的特色资源数据库建设,需要根据它特有的特征来制定专门的元数据元素,来适用特种资源的需要。本文以《煤矿安全与事故案例数据库》和《矿物岩石数据库》为例,说明了特种数据库的元数据的设计依据。

Currently, the metadata of the numeric object possesses an aggregate standard of basic metadata. However, to construct characteristic databases, it needs to establish the special elements of metadata according to their own characteristics, so as to meet the demand of special type of resources. In this study, taking ＂Database of accident case and coal mine safety＂ and ＂Mineral rock database＂ as exemples, the bases for designing the metadata of special type of database are explained.
