GetFeature request for INSPIRE Addresses
IvoSilvestre
I'm trying to send a getfeature request that returns a specific door number from a specific street. This is the request:
"<wfs:GetFeature xmlns:wfs="http://www.opengis.net/wfs" xmlns:gn="urn:x-inspire:specification:gmlas:GeographicalNames:3.0" xmlns:ad="urn:x-inspire:specification:gmlas:Addresses:3.0" xmlns:gml="http://www.opengis.net/gml" xmlns:ogc="http://www.opengis.net/ogc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="1.1.0" xsi:schemaLocation="http://www.opengis.net/wfs http://schemas.opengis.net/wfs/1.1.0/wfs.xsd" outputFormat="text/xml; subtype=gml/3.2.1">
<wfs:Query typeName="ad:Address">
<ogc:Filter>
<ogc:And>
<ogc:PropertyIsEqualTo>
<ogc:PropertyName>ad:component/ad:ThoroughfareName/ad:name/gn:GeographicalName/gn:spelling/gn:SpellingOfName/gn:text</ogc:PropertyName>
<ogc:Literal>STREET NAME</ogc:Literal>
</ogc:PropertyIsEqualTo>
<ogc:PropertyIsEqualTo>
<ogc:PropertyName>ad:locator/ad:AddressLocator/ad:designator/ad:LocatorDesignator</ogc:PropertyName>
<ogc:Literal>DOOR NUMBER</ogc:Literal>
</ogc:PropertyIsEqualTo>
</ogc:And>
</ogc:Filter>
</wfs:Query>
</wfs:GetFeature>"
This is the answer:
<gml:FeatureCollection xsi:schemaLocation="http://www.opengis.net/gml/3.2 http://schemas.opengis.net/gml/3.2.1/deprecatedTypes.xsd urn:x-inspire:specification:gmlas:Addresses:3.0 http://localhost:8080/services?SERVICE=WFS&VERSION=1.1.0&REQUEST=DescribeFeatureType&OUTPUTFORMAT=text%2Fxml%3B+subtype%3Dgml%2F3.2.1&TYPENAME=ad:Address&NAMESPACE=xmlns(ad=urn%3Ax-inspire%3Aspecification%3Agmlas%3AAddresses%3A3.0)" gml:id="WFS_RESPONSE">
</gml:FeatureCollection>
Am I doing any thing wrong?

Hi Ivo,
your request is almost correct, but the second XPath ends too early --
it must always end on a primitive valued element. Try this:
<wfs:GetFeature xmlns:wfs="http://www.opengis.net/wfs"
xmlns:gn="urn:x-inspire:specification:gmlas:GeographicalNames:3.0"
xmlns:ad="urn:x-inspire:specification:gmlas:Addresses:3.0" xmlns:gml="
http://www.opengis.net/gml" xmlns:ogc="http://www.opengis.net/ogc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="1.1.0"
xsi:schemaLocation="http://www.opengis.net/wfs
http://schemas.opengis.net/wfs/1.1.0/wfs.xsd" outputFormat="text/xml;
subtype=gml/3.2.1">
<wfs:Query typeName="ad:Address">
<ogc:Filter>
<ogc:And>
<ogc:PropertyIsEqualTo>
<ogc:PropertyName>ad:component/ad:ThoroughfareName/ad:name/gn:GeographicalName/gn:spelling/gn:SpellingOfName/gn:text</ogc:PropertyName>
<ogc:Literal>Madame Curiestraat</ogc:Literal>
</ogc:PropertyIsEqualTo>
<ogc:PropertyIsEqualTo>
<ogc:PropertyName>ad:locator/ad:AddressLocator/ad:designator/ad:LocatorDesignator/ad:designator</ogc:PropertyName>
<ogc:Literal>14</ogc:Literal>
</ogc:PropertyIsEqualTo>
</ogc:And>
</ogc:Filter>
</wfs:Query>
</wfs:GetFeature>
Best regards,
Markus
P.S.: WFS 2.0 brings some additional query possibilities (e.g.
GetPropertyValue). Support in deegree 3 is not 100% complete yet [1],
but already pretty usable. If your curious, just download a current
SNAPSHOT [2]/[3], log in to the service console, select workspace and
download and start the deegree inspire workspace. You will find some WFS
2.0 example requests in the Generic Client ("send requests").

Now It works. Thank you.
Sorry for my ignorance but you called primitive valued element to "ad:designator"? And why the "ad:designator" is duplicated?
Is there any documentation that explain this?
Regards,
Ivo Silvestre.

Ivo,
IMHO, the following specifications/pieces of documentation are relevant
here:
- - Filter Encoding specification [1]: defines how filters are evaluated
- - INSPIRE Data Specifications [2]: define the actual data model, i.e.
which elements exist and which type they have
In the end (for deegree), the INSPIRE GML Annex I application schemas
[3] (as an encoding of the Data Specifications) define the two
"ad:designator" elements (pretty stupid, I agree) and that the second
one is primitive valued.
Best regards,
Markus
