Title: Public Comment on Changes to the DCMI Type Vocabulary
Identifier: http://dublincore.org/usage/public-comment/2005/12/type-vocabulary-changes/
Date: 2005-12-08

The DCMI Usage Board proposes the attached changes (see below) to definitions and comments of terms of the DCMI Type Vocabulary [1,2]. The changes, which were discussed at recent meetings of the Usage Board [3,4], are essentially editorial in nature:

1) Definitions were wordsmithed for grammatical correctness
   and stylistic consistency.

2) As they were originally written, the definitions of
   DCMI Type terms included information about expected uses
   of the term -- information which, for other types of
   DCMI terms, is typically provided in a separate Comment.
   For stylistic consistency, therefore, parts of the
   current Definitions were split off into Comments.

It is worth noting that the Usage Board did not undertake any more fundamental discussion of the typology offered in the DCMI Type Vocabulary. As clarified in a posting to DC-GENERAL in December 2003 [5], the Usage Board does not intend to expand or otherwise clarify the existing vocabulary; rather, it "prefers to focus on interoperability between the DCMI Type Vocabulary and other, more granular vocabularies created and maintained by communities of interest for specialized uses."

Public comment is therefore solicited primarily not on the concepts underlying the DCMI Types, but on the potential impact of the these editorial changes on existing interpretations and implementations.

Public Comment will be open from 12 December 2005 to 31 January 2006.
