The
subject-matter coverage in terms of one or more periods of time. That is, an
indication of the time period for which the subject of the resource applies.
(E.g. The 50's, or a span of time indicated by a start and end time.) See IRM
Spec Category: Temporal Coverage.
ded:CategoryDescription: Subject matter
coverage expressed in terms of one or more periods of time.

ded:CategoryComment: There can be an unbounded
number of temporalCoverage elements. A temporalCoverage element can include a
textual name. Recommended practice is that temporalCoverage:start and
temporalCoverage:end be specified in one of the following formats: YYYY YYYY-MM
YYYY-MM-DD YYYY-MM-DDThh.mmTZD YYYY-MM-DDThh:mm.ssTZD YYYY-MM-DDThh:mm:ss.sTZD
Where: YYYY 0000 through current year MM 01 through 12 (month) DD 01 through 31
(day) hh 00 through 24 (hour) mm 00 through 59 (minute) ss 00 through 60
(second) .s .0 through 999 (fractional second) TZD = time zone designator (Z or
+hh:mm or -hh:mm) This profile suggests two ways of handling time zone offsets:
1. Times are expressed in UTC (Coordinated Universal Time), with a special UTC
designator (?Z?). 2. Times are expressed in local time, together with a time
zone offset in hours and minutes. A time zone offset of ?+hh:mm? indicates that
the date/time uses a local time zone which is ?hh? hours and ?mm? minutes ahead
of UTC. A time zone offset of ?-hh:mm? indicates that the date/time uses a local
time zone which is ?hh? hours and ?mm? minutes behind UTC. Start and End dates
can now be expressed as being approximate. Additionally, the
temporalCoverage:start and temporalCoverage:end may be specified to be ?not
applicable? or ?unknown? as necessary. If a temporalCoverage element does not
appear, it is equivalent to a temporalCoverage element where all of the
sub-elements are set to ?not applicable? The temporalCoverage element can be
marked according to SMP guidelines.
ded:Definition: An element that defines the subject-matter coverage in terms of
one or more periods of time.
ded:Obligation: (Mandatory Unless Not Applicable)
ded:Comment: This element provides an indication of the time period for which
the subject of the resource applies. (E.g. The 50's, or a span of time indicated
by a start and end time.) The temporalCoverage element can be marked according
to SMP guidelines.
