?
ded:Obligation: (Optional, Mandatory) Optional in ICResourceMetadataPackage.
Mandatory in metacardInfo.
ded:Comment: There must be one dates element under metacardInfo. In this
context the dates element contains information about the metadata card, and must
have an approvedOn attribute populated. An optional dates element in
ICResourceMetadataPackage provides dates associated with a described data asset.
A mandatory dates element in metacardInfo provides dates associated with a
metadata card. Recommended practice is that date be specified in one of the
following formats: YYYY YYYY-MM YYYY-MM-DD YYYY-MM-DDThhTZD 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 (hours) mm = 00 through 59 (minute) ss = 00 through 59 (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. The values "Unknown" and "Not
Applicable" are also supported values for the date category elements. When
optionally used, there can only be one dates element. There can only be one
dates element in ICResourceMetadataPackage. There must be one dates element in
metacardInfo.
