-----------------------------------
Summary: Comparison for DateTimeStamp not working
Key: JENA-2013
URL: https://issues.apache.org/jira/browse/JENA-2013
Project: Apache Jena
Issue Type: Bug
Components: Fuseki
Affects Versions: Jena 3.14.0
Environment: This example dataset with both xsd:dateTime and
xsd:dateTimeStamp specified, loaded into Apache Jena Fuseki:
{code:java}
@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .
@prefix ex: <http://example.org#> .
ex:Foo ex:dateTime "2001-10-26T19:32:52+00:00"^^xsd:dateTime .
ex:Foo ex:dateTimeStamp "2001-10-26T19:32:52+00:00"^^xsd:dateTimeStamp .
{code}
Reporter: Johannes Lipp
*Summary:*
The SPARQL query interface does handle greater/smaller than (< or >) for
xsd:dateTime properly, but does not handle xsd:dateTimeStamp correctly.
*Expected behavior:*
Executing the following query in Fuseki returns one result:
{code:java}
PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>SELECT ?subject ?predicate
?object
WHERE {
?subject ?predicate ?object .
FILTER (?object > "1999-10-26T19:32:52+00:00"^^xsd:dateTimeStamp) .
}
LIMIT 25
{code}
*Actual behavior:*
The query returns no results. Querying via equals (= 2001...) instead of
greater (> 1999...) works. Also, replacing xsd:dateTimeStamp with xsd:dateTime
works as expected - but the xsd:dateTimeStamp does not return anything.
