What is the Dublin core?

The Dublin core is a metadata - data that provides information about other data, such as the data found in the library database - a standard that helps describe network resources. It is a basic set of elements with two levels. The basic level is simple; It has fifteen elements that are used for the catalog and describe the source. The qualified level has fewer elements and is used to specify the input so that it is easier to find and understand. Dublin basic elements are used in places such as libraries and museums and in fields, including text coding and computer science to organize and help in discovering information. They are most commonly found in scientific settings. The field contains basic information as the name, subject, creator name and description. These fields are also immersed in detail, including rights, source and format.

The qualified core level adds dimena flexibility to a simple level of the Dublin core. This level can help increase a more specific and detailed set of elements. QualifiedIt may include information including rights, provenance and audiences. It is usually considered to be an improvement of standard 15 fields than the basic element.

Four primary goals of the Dublin core focus on creating broadly understandable, simple systems for organization and description of resources. One important goal is that the elements are easy to create and maintain, with a simple and efficient design. It is also important that the terminology used in the elements is generally understood across nations and various professions. Another goal is to increase international involvement in the Dublin core by creating the largest languages ​​as possible. The final important goal of the Dublin core is to create a system of images that, although they remain simple, can be infinitely expanded to meet the needs of its users.

There are three basic principles of Dublin that can help creators achieve the goals of the element set. First, called pRincip individual, acknowledges that the original creations and reproductions of the material should be properly distinguished and that administrative authors should be recognized for everyone. In principle, the deep principle states that all values ​​should be used without qualifiers and that any qualifications that exist are for the purposes of improvement and not for basic information communication. The final principle, appropriate values, acknowledges that it can be accessible to the information by a person or machine, and should therefore be presented so that both can be understood.
