| Status of Document: | This the experimental draft of a potential DCMI Recommended Resource |
| Description of Document: | 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 | |
