What Is the Dublin Core?

Dublin Core Technology Dublin Core is a brief catalogue model for identifying electronic resources developed by the international organization Dublin Core Metadata Initiative. It has been recognized by more than 20 countries in North America, Europe, Asia, and Oceania since its appearance. Not only libraries, museums, but also many government agencies and business organizations are adopting or preparing to adopt it.

Dublin Core

It came about because the authors obtained enlightenment from the traditional library readers' inquiry through card catalogs and borrowed the required books: to retrieve electronic resources on the Internet, they can also use the catalog information that reflects these electronic resources. So the drafters of Dublin Core made fifteen generalized metadata by referring to the model of library card catalog.

Copyright information usually includes intellectual property rights (IPR), copyright, and various ownership rights. The absence of a copyright item means that the above copyright and other rights regarding the resource are not taken into account.

Looking at the above 15 items of metadata, it can be seen that: First, it comprehensively summarizes the main characteristics of electronic resources, covering the important access points of resources (1, 2, 3 items), auxiliary access points or related access points (5 , 6, 10, 11, 13), and valuable descriptive information (4, 7, 8, 9, 12, 14, 15). Second is its simplicity and standardization. These 15 items of metadata are not only applicable to electronic literature catalogues, but also to various types of electronic official document catalogues, product, merchandise, and collection catalogues, and have very good practicality.

Dublin Core solves the standard problem of electronic resources, but there are many ways to implement technology. But the most used and most effective technologies in the library field are XML and RDF. Please refer to related research pages
