How to run a temporal query on a CSW using GeoNetwork?

Question

On my GeoNetwork 2.10.3 a CSW GetRecords request (CQL) for TempExtent_begin after a certain date returns all of my metadata records. It seems like the filter expression is simply ignored.

http://myserver:8080/geonetwork/srv/eng/csw?SERVICE=CSW&version=2.0.2
&REQUEST=GetRecords&resultType=results
&constraintLanguage=CQL_TEXT&constraint_language_version=1.1.0
&constraint=TempExtent_begin%20after%202014-10-12T00:00:00Z
&elementSetName=full&outputSchema=http://www.isotc211.org/2005/gmd

Is this a problem of GeoNetwork or is there something wrong with my request?

Answer 1

Thanks for reply. I didn't know this log file. Really a great help!

Here is the solution for my problem:

http://myserver:8080/geonetwork/srv/eng/csw?SERVICE=CSW&version=2.0.2
&REQUEST=GetRecords&resultType=results
&constraintLanguage=CQL_TEXT&constraint_language_version=1.1.0
&constraint=TempExtent_begin%20>=%20'2014-10-12T00:00:00Z'
&elementSetName=full&outputSchema=http://www.isotc211.org/2005/gmd

Operations AFTER and BEFORE are not supported. You have to use <= and >= instead. Furthermore you have to quote the <DateTime>.

If I try your request on the latest version of geonetwork, this is what the console output shows:

014-10-15 08:11:30,577 INFO [jeeves.service] - Dispatching : csw 2014-10-15 08:11:30,580 INFO [jeeves.webapp.csw] - Received: full 1.1.0 http://www.isotc211.org/2005/gmd CSW TempExtent_begin after 2014-10-12T00:00:00Z results CQL_TEXT GetRecords 2.0.2 2014-10-15 08:11:30,581 INFO [jeeves.webapp.csw] - Dispatching operation : GetRecords oct 15, 2014 8:11:34 AM org.geotools.xml.impl.ParserHandler error ADVERTENCIA: cvc-complex-type.2.4.b: The content of element 'ogc:Filter' is not complete. One of '{"http://www.opengis.net/ogc":spatialOps, "http://www.opengis.net/ogc":comparisonOps, "http://www.opengis.net/ogc":logicOps, "http://www.opengis.net/ogc":_Id}' is expected.

So your spatial filter seems to be incomplete or wrong.
