Bug with xsd:date datatype
Hi,
I use Jena 2.10.1 to compute the age of people from french DBpedia dataset.
When I retrieve a date, sometimes, this code "date.getValue()", where
"date" is a "Literal", gives me an exception :
Lexical form '1993-11-31' is not a legal instance of Datatype[
http://www.w3.org/2001/XMLSchema#date].
Whereas in the dataset the value is "1993-11-31"^^
http://www.w3.org/2001/XMLSchema#date (even the toString() function gives
me this value).
I did something wrong or is-it a bug from Jena ?
Thanks in advance.
Julien.

Jena implement the W3C standard most ( all ? ) the time.
The W3C standard about the xsd:datetime says :
[...]The value of each numeric-valued property
(other than timeOnTimeline) is limited to the maximum value within the interval
determined by the next-higher property. For example, the day value can never be 32,
and cannot even be 29 for month 02 and year 2002 (February 2002).[...]

So to answer your question :
>Off course no, but the jena intern process check the date validity ?
I'm not 100% sure, but I say yes, it's very likely that appends.
