 Everybody 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 :

 As 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 :

 You 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 :

 As 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 :

 Finally, please note that we go back to the default {{{mimeType}}} to directly obtain the JSON string as we will use this kind of request to develop our client application in the next section of this workshop.
