Hi Andrea,
First of all sorry for guessing you were female. It must be a cultural thing
because the spelling of Andrea in Australia is *usually* for females. I hope
you forgive me. ;--)
Please see my comments below:
Thanks.
John

> Great! Thanks.Further investigation has revealed that you can choose both formats.
dateStamp is a gco:Date_PropertyType which type is:<xs:complexType name="Date_PropertyType">
<xs:choice minOccurs="0">
<xs:element ref="gco:Date"/>
<xs:element ref="gco:DateTime"/>
</xs:choice>
<xs:attribute ref="gco:nilReason"/>
</xs:complexType>As you can see we have a choice between a date and a date-time.
Thank you for pointing this out to me. The ISO 19115 standard specifies
'dateStamp' is of 'Date' type. The 'Date' type is identified in section B4.2
of ISO 19115 as:
"Date: gives values for year, month and day. Character encoding of a date is
a string which shall follow the
format for date specified by ISO 8601. This class is documented in full in
ISO/TS 19103."
Some date searching and indexing software will only work on dates and not
dateTime format.
I will have to mention this to the ISO 19139 developers.
Thanks.
