[Mapbender-dev] WFS 1.1 design phase

Currently I'm thinking about how to redesign some Mapbender PHP classes 
in order to support WFS 1.1.0.

We are having a single class for a WFS. Its attributes are set by 
methods like

createObjFromXML (the data is taken from a capabilities document) or
createObjFromDB (the data is already stored in Mapbender).

Of course, a capabilities document of version 1.1.0 different from a 
1.0.0 document. So I have to enhance the current static model into a 
more dynamic one.

We should have an abstract WFS class (maybe even an abstract OWS class), 
and then let WFS_1_1 and WFS_1_0 inherit from WFS.

In order to keep most of the code intact, I wanted to avoid sth. like

$wfs = new WFS_1_1();
$wfs = new WFS_1_0();

so I was thinking about using a factory method approach.


A WFS factory would create WFS objects, we would not have to create them 
ourselves. A WFS factory could have the methods mentioned above,

createObjFromXML and

which would return either a WFS 1.1.0 or a WFS 1.0.0 object. The current 
class wfs could be rewritten to be this factory. By this we could at 
least keep some code intact.

I sketched the classes here


Let's discuss and feel free to edit the wiki page.
