Hi Jerven,
this looks like a pragmatic solution. But I wonder if it may lead to any
conflicts, e.g., the vcard ontology defines the bday property with
xsd:dateTime as its range explicitly. Is it "safe" to simply use an
xsd:gYear value as its object?
Best,
Heiko

Hi Heiko,
http://www.w3.org/TR/xmlschema-2/#gYear and
http://www.w3.org/TR/xmlschema-2/#gYeargYearMonth
are the datatypes that you should use.
Regards,
Jerven

Hi all,
xsd:dateTime and xsd:date are used frequently for encoding dates in RDF, e.g.,
for birthdays in the vcard ontology [1]. Is there any best practice to encode
incomplete date information, e.g., if only the birth *year* of a person is
known?
As far as I can see, the XSD spec enforces the provision of all date components [2], but
"1997-01-01" seems like a semantically wrong way of expressing that someone is
born in 1997, but the author does not know exactly when.
Thanks,
Heiko
