Let me stew on this a bit more. Generally speaking, I think the dcterms
are too loosely defined, but let me see if I can't get this to grow on me.

Just a follow-up on the representation of Date Ranges in dublin
core. I was under the mistaken impression that you needed to use a
DCMI Period encoding to represent a date range, but apparently ISO
8601 time intervals are perfectly valid. In order to clarify the
situation, the DC Date Working Group has recently recommended the
following replacement for the comment associated with the date element:
"Typically, Date will be associated with the creation or
availability of the resource. A date value may be a single date or a
date range. Date values may express temporal information at any
level of granularity (including time). Recommended best practice for
encoding the date value is to supply an unambiguous representation
of the single date or date range using a widely- recognized syntax
(e.g., YYYY-MM-DD for a single date; YYYY-MM-DD/ YYYY-MM-DD for a
date range; YYYY-MM-DDTHH:MM to specify a single date and time down
to the minute)."
Full details of the recommendation can be found here:

Personally I think that makes the idea of using dublin core for this
extension a whole lot more palatable.
