Dublin Core™ Grammatical Principles
When the DCMI Usage Board was founded in 2001, it formulated DCMI Grammatical Principles as a point of reference for vocabulary maintenance decisions. The principles, which followed concepts, that had emerged in early Dublin Core™ workshops, such as Element, Qualifier, and Encoding Scheme, were superseded in 2005 by the DCMI Abstract Model, which was based more explicitly on RDF.
