[Zoo-discuss] WPS Execute request - the ResponseForm

[Alexandre Dubé]

Hi list,

   I'd like to raise this discussion again.

   I was told that what OpenLayers outputs is fine:

<wps:ResponseForm>

   <wps:RawDataOutput>

     <ows:Identifier xmlns:ows="http://www.opengis.net/ows/1.1">Result</ows:Identifier>

   </wps:RawDataOutput>

</wps:ResponseForm>


   In the above, the mimeType="application/json" is missing. attribute 
missing but that can be easily fixed on my side.  It's the missing 
Output tag that zoo requires that is not there and I want to be sure if 
it should be there or not.  I.E., I want to know where this should be 
fixed: in Zoo or OpenLayers.

   The answer is there, in the schema, but I'm not familiar enough with 
what its content means. 
http://schemas.opengis.net/wps/1.0.0/wpsExecute_request.xsd

   Thoughts ?

Alexandre
