DCMI维护着一个包含众多元数据术语的词表,其中最主要的是包括15个元素的都柏林核心。然而,DCMI 所关注和讨论的并不只是这个核心集,以及围绕这个核心集的实践、策略和模型,DC 元数据模型已经由最初的单一模型进化成一个完整的框架,可以通过这个框架对应用 DC 元数据的各种实践进行评估。这些术语及其以前的版本现在都由统一资源标识符(URI)来标识,并建立了网页和形式化的 schema 文档,在注册系统中被编成索引,在具体的应用纲要(application profiles)中被引用。DCMI 正在寻求一种简单易行的维护机制,一方面推荐使用不断变化和增长的核心标准,另一方面承认和重用其它的词表作为必要的补充,这两者之间需要建立一种平衡。
DCMI maintains a list of many metadata terms, the most important of which is the 15-element Dublin Core. However, DCMI’s focus and discussion is not just about this core set, but also about the practices, strategies, and models surrounding this core set. The DC metadata model has evolved from an initial single model into a complete framework through which applications, DC metadata to evaluate various practices. These terms, as well as their previous versions, are now identified by Uniform Resource Identifiers (URIs) and web pages and formal schema documents are created and indexed in the registration system. In specific application profiles Cited. DCMI is seeking a simple and easy maintenance mechanism that recommends balancing the core parameters of changing and growth, while recognizing and reusing other vocabularies as necessary complements.
