[Chameleon] Extract from WFS

[Gail]

Hi Bart and Chameleon List

I have a few questions to ask about the e-mail you sent to me about WFS in
Chameleon.

>The ExtractWFS widget uses the WFS GetFeature interface to get its data. It
>can then output in the form of GML (or shapefile if you have the php_ogr
>extension).

What are you referring to when you say WFS GetFeature interface is this the
.map file?

>So if you have a CONNECTIONTYPE WMS layer in your Chameleon MAP file,
>Chameleon will see if the WMS layer is associated with a WFS interface
>using a WMS DescribeLayer request. If you have a CONNECTIONTYPE WFS layer

>the appropriate bounding box.

How does the WMS DescribeLayer request get initiated?
I have added connectiontype wfs in the .map file but nothing is happening a
GetFeature request I don't think is being sent to the server, any
suggestions on why this might be?

How is the WFS interface set up and where can I find an example of what the
DM Solutions group have done to create the WFS interface?

Kind Regards
