Hi Kieran,
For time range query (inclusive range) post a request like this:
<?xml version="1.0" encoding="UTF-8"?>
<csw:GetRecords xmlns:csw="http://www.opengis.net/cat/csw/2.0.2" service="CSW" version="2.0.2" resultType="results" outputSchema="http://www.isotc211.org/2005/gmd" maxRecords="1000">
<csw:Query typeNames="dataset,application,datasetcollection,service">
<csw:ElementSetName>full</csw:ElementSetName>
<csw:Constraint version="1.1.0">
<ogc:Filter xmlns:ogc="http://www.opengis.net/ogc" xmlns:gml="http://www.opengis.net/gml">
<ogc:And>
<ogc:PropertyIsGreaterThanOrEqualTo>
<ogc:PropertyName>TempExtent_begin</ogc:PropertyName>
<ogc:Literal>2010-10-01T01:01:01Z</ogc:Literal>
</ogc:PropertyIsGreaterThanOrEqualTo>
<ogc:PropertyIsLessThanOrEqualTo>
<ogc:PropertyName>TempExtent_end</ogc:PropertyName>
<ogc:Literal>2010-10-31T23:59:59Z</ogc:Literal>
</ogc:PropertyIsLessThanOrEqualTo>
</ogc:And>
</ogc:Filter>
</csw:Constraint>
</csw:Query>
</csw:GetRecords>
Note that there is some conversion from date_time in the metadata to date_time
stored in Lucene index against which the query is run as follows:
***Conversion from d_t in XML metadata to d_t in Lucene****
I have confirmed the following conversion behvaiour by Lucene for date/time
entered in ISO8601 format:
-date/time suffixed with 'Z' remain unconverted i.e the time remains in GMT
-date/time with no suffix are assumed to be local times and are converted
to GMT based on time zone of the local computer by lucene. e.g if you entered
2007-06-01T00:00 (in Sydney GMT+10) it would be converted to
2007-05-31T14:00:00.00Z for storage in Lucene's index.
-date/times with a time zone offset e.g +10:00 have the offset added or subtracted
as appropriate for conversion back to GMT. e.g if I entered 2007-12-04T00:00+10:00
in the XML file it is converted to 2007-12-03T14:00:00.000Z in lucene index

To find records with that polygon you could try posting a bounding box
query like this but not sure if this would pick up the polygons, I know this
works for metdata with GeographicBoundingBox. Try something
like anyway:
<?xml version="1.0" encoding="UTF-8"?>
<csw:GetRecords xmlns:csw="http://www.opengis.net/cat/csw/2.0.2" service="CSW" version="2.0.2" resultType="results" outputSchema="http://www.isotc211.org/2005/gmd" maxRecords="1000">
<csw:Query typeNames="dataset,application,datasetcollection,service">
<csw:ElementSetName>full</csw:ElementSetName>
<csw:Constraint version="1.1.0">
<ogc:Filter xmlns:ogc="http://www.opengis.net/ogc" xmlns:gml="http://www.opengis.net/gml">
<ogc:Within>
<ogc:PropertyName>ows:BoundingBox</ogc:PropertyName>
<gml:Envelope>
<gml:lowerCorner>141.0 -39.0</gml:lowerCorner>
<gml:upperCorner>150.0 -34.0</gml:upperCorner>
</gml:Envelope>
</ogc:Within>
</ogc:Filter>
</csw:Constraint>
</csw:Query>
</csw:GetRecords>

Subject: [GeoNetwork-users] CSW - GetRecords (filter time range and polygon)
Hello GeoNetwork users,
I am looking for the right GetRecords request body for the following searches:
* time range (TempExtent_begin and TempExtend_end see: OGC 07-045 p. 48) which is coded in the metadata xml like this:
<gmd:EX_TemporalExtent> <gmd:extent> <gml:TimePeriod gml:id="IDcd3b1c4f-b5f7-439a-afc4-3317a4cd89be" xsi:type="gml:TimePeriodType"> <gml:beginPosition>2010-10-17T11:15:00+01:00</gml:beginPosition> <gml:endPosition>010-10-17T11:15:00</gml:endPosition> </gml:TimePeriod> </gmd:extent> </gmd:EX_TemporalExtent>
* a polygon, which is coded in the metadata xml like this:
<gmd:geographicElement> <gmd:EX_BoundingPolygon> <gmd:extentTypeCode> <gco:Boolean>true</gco:Boolean> </gmd:extentTypeCode> <gmd:polygon> <gml:Polygon gml:id="Pg1"> <gml:exterior> <gml:LinearRing> <gml:coordinates>5.29517,59.623 ...</gml:coordinates> </gml:LinearRing> </gml:exterior> </gml:Polygon> </gmd:polygon> </gmd:EX_BoundingPolygon> </gmd:geographicElement>
Can anyone help me?
Greetings, Kieran
