In this recipe, you first created a point PostGIS table and then published it as WFS-T, using GeoServer. You then created a basic OpenLayers application, using the WFS-T layer, allowing the user to add features to the underlying PostGIS layer.
In OpenLayers, the core object needed to implement such a service is the vector layer by defining a WFS protocol. When defining the WFS protocol, you have to provide the WFS version that is using the spatial reference system of the dataset, the URI of the service, the name of the layer (for GeoServer, the name is a combination of the layer workspace, FeaturePrefix, and the layer name, FeatureType), and the name of the geometry field that will be modified. You also can pass to the Vector ...
