This article mainly introduces what is the use of Dublin Core in XML mode. It is very detailed and has a certain reference value. Interested friends must finish reading it!

Dublin Core standard is a method of information classification, which is often used in libraries. The Dublin Core standard has a XML Schema that defines how to use XML to describe such information. Dublin Core can effectively catalog all kinds of information and make it easy to modify, query, and use. The current application of Dublin Core in information description and definition makes semantic Web a reality. Pass

Dublin Core standard is a method of information classification, which is often used in libraries. The Dublin Core standard has a XML Schema that defines how to use XML to describe such information. Dublin Core can effectively catalog all kinds of information and make it easy to modify, query, and use.

The current application of Dublin Core in information description and definition makes semantic Web a reality. By using a unified standard to describe data and, more importantly, using well-designed and proven solutions, data in other XML documents can be described in detail, so that information can be effectively exchanged and compared between different sources.

The Dublin Core specification has its own schema, but its purpose is to embed a larger XML document, using XML namespaces to define the DC elements needed to describe other data in the document. As an example, read listing 10 to see how the DC classification system can be used in the RDF XML schema to describe the content of RDF entities, such as Web sites. To do this, you can extend the structure in the previous RDF schema example.

Listing 10 uses the DC element to add description, topic, publisher, copyright, and identifier information to classify RSS feeds.

The complete Dublin Core Metadata Elements Set consists of 15 metadata elements.
