Hi,
I would like to precise a point about my previous question. Using “>=” or “<=” symbol with CreationDate or RevisionDate field to define a constraint works well but I can’t do the same thing with the TempExtent_begin or TempExtent_end.
As an example, the records I try to retrieve have however similar information set:
<gmd:temporalElement>
<gmd:EX_TemporalExtent>
<gmd:extent>
<gml:TimeInstant xmlns:gml="http://www.opengis.net/gml/3.2">
<gml:timePosition>2016-12-05T13:51:12Z</gml:timePosition>
</gml:TimeInstant>
</gmd:extent>
</gmd:EX_TemporalExtent>
</gmd:temporalElement>
How to define a CQL constraint based on the temporalExtent with Geonetwork v3.0.4?
Thanks,
Fanny

Dear all,
I am trying to get Records from my Geonetwork catalog (v3.0.4) using a temporal CQL filter. I have tried various solution but none works. I send the following request
http://<host>/geonetwork/srv/fre/csw?outputSchema=http%3A%2F%2Fwww.isotc211.org%2F2005%2Fgmd&ElementSetName=full&TypeName=gmd%3AMD_Metadata&NAMESPACE=xmlns%28csw%3Dhttp%3A%2F%2Fwww.opengis.net%2Fcat%2Fcsw%2F2.0.2%29%2Cxmlns%28ogc%3Dhttp%3A%2F%2Fwww.opengis.net%2Fogc%29%2Cxmlns%28ows%3Dhttp%3A%2F%2Fwww.opengis.net%2Fows%29%2Cxmlns%28dc%3Dhttp%3A%2F%2Fpurl.org%2Fdc%2Felements%2F1.1%2F%29%2Cxmlns%28dct%3Dhttp%3A%2F%2Fpurl.org%2Fdc%2Fterms%2F%29%2Cxmlns%28gml%3Dhttp%3A%2F%2Fwww.opengis.net%2Fgml%29%2Cxmlns%28xsi%3Dhttp%3A%2F%2Fwww.w3.org%2F2001%2FXMLSchema-instance%29&VERSION=2.0.2&SERVICE=CSW&MaxRecords=10&RESULTTYPE=results&outputFormat=application%2Fxml&StartPosition=1&REQUEST=GetRecords&CONSTRAINTLANGUAGE=CQL_TEXT&CONSTRAINT_LANGUAGE_VERSION=1.1.0&Constraint=....
with different constraints to test with:
- With XPath
o Constraint=gmd:identificationInfo.gmd:MD_DataIdentification.gmd:extent.gmd:EX_Extent.gmd:temporalElement.gmd:EX_TemporalExtent.gmd:extent.gml:TimeInstant.gml:timePosition%20>=%20'2015-01-01T01:37:12Z'
==> Returns no records
o Constraint=gmd:identificationInfo.gmd:MD_DataIdentification.gmd:extent.gmd:EX_Extent.gmd:temporalElement.gmd:EX_TemporalExtent.gmd:extent.gml:TimeInstant.gml:timePosition%20after%202015-01-01T01:37:12Z
==> Returns all of my records
- With ISOQueryables (TempExtent_begin listed in the GetCapabilities response <ows:Constraint name="SupportedISOQueryables">) :
o Constraint=TempExtent_begin%20>=%20'2015-01-01T01:37:12Z'
==> Returns no records
o Constraint=TempExtent_begin%20after%202015-01-01T01:37:12Z
==> Returns all of my records
Do you have any hints about it ?
Thanks a lot,
Fanny
