The Dublin Core™ metadata standard is a simple yet effective element set for describing a wide range of networked resources. The Dublin Core™ standard includes two levels: Simple and Qualified. Simple Dublin Core™ comprises fifteen elements; Qualified Dublin Core™ includes three additional elements (Audience, Provenance and RightsHolder), as well as a group of element refinements (also called qualifiers) that refine the semantics of the elements in ways that may be useful in resource discovery.

DC Principals

1 The One-to-One Principle.

<bloqkquote>In general Dublin Core™ metadata describes one manifestation or version of a resource, rather than assuming that manifestations stand in for one another. For instance, a jpeg image of the Mona Lisa has much in common with the original painting, but it is not the same as the painting. As such the digital image should be described as itself, most likely with the creator of the digital image included as a Creator or Contributor, rather than just the painter of the original Mona Lisa. The relationship between the metadata for the original and the reproduction is part of the metadata description, and assists the user in determining whether he or she needs to go to the Louvre for the original, or whether his/her need can be met by a reproduction.

2. The Dumb-down Principle.

According to this rule, a client should be able to ignore any qualifier and use the value as if it were unqualified. While this may result in some loss of specificity, the remaining element value (minus the qualifier) must continue to be generally correct and useful for discovery. Qualification is therefore supposed only to refine, not extend the semantic scope of a property.

3. Appropriate values.

Best practice for a particular element or qualifier may vary by context, but in general an implementor cannot predict that the interpreter of the metadata will always be a machine. This may impose certain constraints on how metadata is constructed, but the requirement of usefulness for discovery should be kept in mind.

In general, all Dublin Core elements are optional and repeatable.

Darwin Core - Simple Darwin Core is a predefined subset of the terms that have common use across a wide variety of biodiversity applications. The terms used in Simple Darwin Core are those that are found at the cross-section of taxonomic names, places, and events that document biological occurrences on the planet. The two driving principles are simplicity and flexibility.
