    522522Everybody should now get his own copy of the OGR Boundary Service stored as a ZOO Services Provider called ogr_ws_service_provider and deployed in the ZOO Kernel tree, so the following Execute request can be used to test the Service :

    530530As you can see in the url above, we use an URLEncoded WFS request to the Geoserver WFS server available on OSGeoLive as a {{{xlink:href}}} key in the {{{DataInputs}}} KVP value, and set the {{{InputPolygon}}} value to {{{Reference}}}. The corresponding non encoded WFS request is as follow :
    531531
    532 [http://localhost:8082/geoserver/ows/?SERVICE=WFS&REQUEST=GetFeature&VERSION=1.0.0&typename=topp:states&SRS=EPSG:4326&FeatureID=states.15]
     532[http://localhost/cgi-bin/mapserv?map=/var/www/wfs.map&SERVICE=WFS&REQUEST=GetFeature&VERSION=1.0.0&typename=regions&SRS=EPSG:4326&featureid=regions.3192]
    533533
    534534Please note that you can add lineage=true to the previous request if you need to get information about the input values used to run your Service. Furthermore, you may need to store the {{{ExecuteResponse}}} document of your ZOO Service to re-use it later. In this case you must add {{{storeExecuteResponse=true}}} to the previous request. Note that is an important thing as the behavior of ZOO Kernel is not exactly the same than when running without this parameter settled to true. Indeed, in such a request, ZOO Kernel will give you an {{{ExecuteResponse}}} document which will contain the attribute statusLocation, which inform the client where the ongoing status or the final {{{ExecuteResponse}}} will be located.
     
    542542You didn't specify any {{{ResponseForm}}} in the previous request, it is not requested and should return a {{{ResponseDocument}}} per default using the {{{application/json}}} {{{mimeType}}} as you defined in you zcfg file. Nevertheless, you can tell ZOO Kernel what kind of data you want to get in result of your query adding the attribute {{{mimeType=text/xml}}} to your {{{ResponseDocument}}} parameter. Adding this parameter to the previous request will give us the result as its GML representation :

    550550As defined by the WPS specifications, you can also ask for a {{{RawDataOutput}}} to get only the data without the full {{{ResponseDocument}}}. To do that, you only have to replace the {{{ResponseDocument}}} of your request by {{{RawDataOutput}}}, like in the following request :
