These updated schemas are meant to replace:
-- currently resolved to by http://purl.org/dc/elements/1.1/
-- currently resolved to by http://purl.org/dc/terms/
-- currently resolved to by http://purl.org/dc/dcmitype/
There has been discussion in breakout sessions in Florence
and in the Usage Board about alternatives to this model,
but until the new model is in place we need to update the
data expressed within the old model, so these new schemas
are most welcome.
Just two comments:
1) | <dcterms:issued xml:lang="en-US">1999-07-02</dcterms:issued>
| <dcterms:modified xml:lang="en-US">2002-10-04</dcterms:modified>
xml:lang seems unnecessary for dcterms:issued and
dcterms:modified, though perhaps it does no harm?
2) | <dc:type rdf:resource="http://dublincore.org/usage/documents/principles/#element"/>
-- Harry's schemas declare "Type of Term" using dc:type.
http://purl.org/dc/elements/1.1/type is defined as
"The nature or genre of the content of the resource"
with the comment: "Type includes terms describing general
categories, functions, genres, or aggregation levels for
content. Recommended best practice is to select a value
from a controlled vocabulary (for example, the DCMI
Type Vocabulary). To describe the physical or digital
manifestation of the resource, use the Format element."
-- Eric, in prototype schemas he generated after the
discussions in DC2002 (see
uses rdf:type for this instead of dc:type.
defined simple as: "Identifies the class of a resource."
Perhaps we should eventually create a dcu:type -- a Usage
Board element specifically defined as the "DCMI Type of
Term". For now, rdf:type seems like perhaps the better fit?
