    Description: Kernel metadata is a small prescriptive vocabulary designed to support highly uniform but minimal object descriptions for the purpose of orderly collection management.

    Note: This is the experimental draft of a potential DCMI Recommended Resource description. This experimental document provides a landing page for Kernel metadata. It has no official status, has not been publicized, and if found, should not be cited.

    Kernel metadata is a small prescriptive vocabulary designed to support highly uniform but minimal object descriptions for the purpose of orderly collection management. Based on a subset of Dublin Core terms, it aims to describe objects of any form or category, but its reach is limited to a small number of fundamental questions such as who, what, when, and where.

    The Kernel metadata specification provides a comprehensive description of Kernel metadata and Electronic Resource Citations (ERCs). It includes rules for converting between Kernel terms and DCMI Metadata Terms. As a supplement, this document explicitly enumerates each mapping from DCMI terms to Kernel terms in the table below. A reverse mapping is not necessarily defined, for example, see the Kernel term "who".

    DCMI Term Relation Kernel Term Notes
    dct:creator 1st choice for who If it is available, "creator" is the same as "who".
    dct:contributor 2nd choice for who If it is available, and "creator" is not available, "contributor" is the same as "who".
    dct:publisher 3rd choice for who If it is available, and neither "creator" nor "contributor" is available, "publisher" is the same as "who".
    dct:title owl:sameAs what
    dct:date owl:sameAs when
    dct:identifier owl:sameAs where
    dct:subject (personage) owl:sameAs about-who Applies when a subject term is known to identify a personage.
    dct:subject owl:sameAs about-what
    dct:temporal owl:sameAs about-when
    dct:spatial owl:sameAs about-where
    dct:description owl:sameAs about-how

    2. n2t.net/ark:/99152/ – ARK prefix reserved for metadata terms
