[GeoNetwork-users] CSW GetRecords Question

Desiree_Hilbring · January 28, 2008, 4:47pm

Hello everybody,

I just installed GeoNetwork this morning and received the "Hydrological Basins in Africa (Sample record, please remove!)" sample data, which I can search for via the web interface.

Now, I want to access the same catalogue entry via the GetRecords operation of the CSW interface.
Via the "CSW 2.0.1 test application" I can create the following request:

POST /geonetwork/srv/en/csw
User-Agent: Jakarta Commons-HttpClient/3.0.1
Host: localhost:8080
Content-Length: 636
Content-Type: application/xml; charset=UTF8

<?xml version="1.0" encoding="UTF-8"?>
<csw:GetRecords xmlns:csw="http://www.opengis.net/cat/csw" service="CSW" version="2.0.1" resultType="results" startPosition="1" maxRecords="10">
  <csw:Query>
    <csw:ElementSetName>full</csw:ElementSetName>
    <csw:Constraint version="1.1.0">
      <Filter xmlns="http://www.opengis.net/ogc" xmlns:gml="http://www.opengis.net/gml">
        <PropertyIsLike wildCard="%" singleChar="_" escape="\">
          <PropertyName>AnyText</PropertyName>
          <Literal>%AFRICA%</Literal>
        </PropertyIsLike>
      </Filter>
    </csw:Constraint>
  </csw:Query>
</csw:GetRecords>

This results to the response:

<csw:SearchStatus status="complete" />
<csw:SearchResults numberOfRecordsMatched="0" numberOfRecordsReturned="0" elementSet="full" />
</csw:GetRecordsResponse>

What is a valid request to receive a match for the catalogue entry?

Best regards,

Desiree

Hi Desiree,

For me, a filter such as :
<?xml version="1.0" encoding="UTF-8"?>
<Filter xmlns="http://www.opengis.net/ogc"
xmlns:gml="http://www.opengis.net/gml">
  <And>
    <PropertyIsLike wildCard="%" singleChar="_" escape="\">
      <PropertyName>any</PropertyName>
      <Literal>africa%</Literal>
    </PropertyIsLike>
  </And>
</Filter>
works fine using propertyName = any instead of AnyText. Maybe a more
general question is what kind of propertyName is supported by the csw
service of GeoNetwork ? is the search criteria of the main.search
service works with the csw service (ie. any, themekey, category, paper,
digital, title, abstract, bbox ...) ?

Thanks
Francois

Yes that worked for me as well. Reading http://geonetwork-opensource.org/documentation/how-to/testing-the-ogc-csw-2-0-1-compliance, I assumed that the CSW interface would support
the core queryable properties of the CSW 2.0.1 Spec, Section 6.3.2.
That is not the case?
Where do I find a list of the search criteria of main.search?

Thanks Desiree

I don't know.

Where do I find a list of the search criteria of main.search?

You could go to the main page, click on the "advanced" search and if
using Firefox, right click, page info, forms tab and advsearch forms.
Here you have all search criteria defined in the user interface.

Another option is to have a look to lucene.xml file.
