The Dublin Core Metadata Element Set is one of the simplest and most widely used metadata schema. Originally developed to describe web resources, Dublin Core has been used to describe a variety of physical and digital resources.
Dublin Core is comprised of 15 “core” metadata elements; whereas the "qualified" Dublin Core set includes additional metadata elements to provide for greater specificity and granularity.
Built into the Dublin Core standard are definitions of each metadata element – like native content standard – that state what kinds of information should be recorded where and how. Associated with many of the data elements are data value standards such as the DCMI Type Vocabulary and ISO 639 language codes, etc. More information can be found on the Dublin Core Metadata Initiative website.
