This page deals with exeriments with the WFS protocol and OpenLayers maps. First was a query on GIS Stackexchange where the user wanted to know if they could use a WFS layer as a baselayer. A quick experiment showed the answer was yes you can.
I was also experimenting with how to use an SLD style to colour in the WFS layer, the code is in the above example but it is clearer in this example. Currently it needs work as I can't figure how to get the text labels to show up.
The next experiment was to add selection to a WFS layer, the final code is here. As you click on states they are selected and the status div is updated with a list of state names. It would be nicer if you could still use the mouse to draw a zoom box box but that would require adding more code to make it a modal tool set.
