In the national digital library project CDLS, 11 descriptive metadata standards are designed based on a set of guides, in which metadata structure and extended rules are two key issues. This paper focuses on these two keys, and illustrates the metadata basic structure, the composing elements, and the extended rules. It takes the metadata standard for ancient atlases as an example and does a case study on how these two issues act on the standard. This can provide a model for enhancing interoperability among the metadata standards of different resource objects. In this study, Dublin Core elements are adopted in equivalent, as far as possible, and are localized in Chinese metadata standards. |
