Qualified Dublin Core (QDC)

Maintained by the Dublin Core Metadata Initiative (DCMI).

Qualified Dublin Core, also known as DC Terms, is an extension of Simple Dublin Core through the use of additional elements, element refinements, and encoding schemes. Qualified Dublin Core is seen in widely differing implementations, often using locally-defined refinements and encoding schemes. Some digital asset management systems such as CONTENTdm and DSpace operate on top of native Qualified Dublin Core models. DC Terms is the basis for most recent activity in the Dublin Core Metadata Initiative, providing the fundamental properties that are used in description sets conforming to the Dublin Core Abstract Model (see DCAM).
