Task Group and Kernel Application Profile (KAP)

Kernel Task Group Wiki:

http://dublincore.org/kernelwiki/

The DCMI Kernel Metadata Task Group was set up to complete the Kernel Application Profile (KAP). This includes the following tasks:

• Compare the core DC semantics and DCMI Abstract Model with kernel metadata elements and the Electronic Resource Citation (ERC) requirements for kernel-based resource descriptions.
• Define a mapping between the Kernel description model and the description model provided by the DCMI Abstract Model (eg, how the Kernel "story" concept affects the meaning of an element label).
• Clarify the nature and status of Kernel elements and their relationships to DCMI terms.

Background

Have you ever wanted a citation format that is both natural to read and simple to process?

     erc: Kunze, John A. | A Metadata Kernel for Electronic Permanence
          | 20011106 | http://jodi.ecs.soton.ac.uk/Articles/v02/i02/Kunze/

The citation above exemplifies the simplest kernel metadata object description, answering the basic who, what, when, where questions regarding the expression of a work. In this case, the expression in question is the publication of an article, coincidentally, about a streamlined metadata record description called ERC (Electronic Resource Citation) base on a kernel set of metadata elements. Although digital permanence is the central application covered in the article, the format works well for more general resource description.

The record design starts with the Dublin Core consensus and distills out a subset of four semantic buckets - a metadata kernel - that balances the needs for adequate identification of persistent objects and for low cost metadata generation. To minimize the burden of creating, understanding, and manipulating data in those buckets, a very simple record format was created.

The basic format can be parsed by two lines of Perl code. This fundamental simplicity suggests an alternative path for the ongoing development of schemes that wish to make metadata easy to create, maintain, and interpret. The Kernel record aspires to offer a way forward for Dublin Core metadata that is simultaneously simpler, and yet more complete, compact, extensible, and international than other syntactical representations.

Historical

• A meeting of the DC-Kernel/ERC Working Group, the predecessor of the DCMI Kernel Metadata Community and Kernel Task Group, took place on Wednesday 4 October 2006 during the DC-2006 conference in Manzanillo, Mexico. The meeting agenda and brief meeting report are available, as well as the meeting's three presentations: Working Group status and overview, Kernel and the DCMI Abstract Model, and Kernel meets Tools Working Group.
